Boat trailer woes 2

 Some photographs which sum up the situation. 

Living on a narrow road which has a bus route does pose problems. As does a steep driveway. If I knew everything would go OK and I could get new wheels and hub assemblies on without any problems, then I would do this on the roadway during the day and then get the boat back on the drive before the evening rush hour. 

However, the chance of a problem which would mean the boat staying on the roadside for a few days is a no-no - from the council, bus, neighbours viewpoint and rightly so. Parking is very difficult along the road as it is. 

The issue has arisen because I didnt show due diligence. The boat has practically been on the drive for two years. During the pandemic I have been out about six times in two years. Very infrequent and so I didnt keep an eye on the trailer as I should have and normally would do. 

All the wobble rollers need to have washers and split pins replaced

the wheel rims are rusting; the hub studs and nuts are very rusted

So, wheels and hubs need replacing

here is my real dilemma. The box section on the left is part of the trailer assembly - a permanently welded on section. The hub spindle is knocked into this box section between four rubber bungs. This spindle/hub/suspension section is showing suddenly very bad corrosion. I have never seen it like this before. The outer layers are flaking off. 

Some of the keel rollers have suddenly collapsed or broken - so the skeg isn't resting correctly on the rear roller. One of the little rollers has managed to break off as well!

The trailer is fourteen years old (I checked last night) and I am wondering whether the sensible thing would be to just replace the whole axle assembly completely

would some work with a wire drill brush clean the spindles and spindle suspensions arm up enough? 

This all needs replacing with a proper adjustable bow keel roller assembly

these wobble rollers are beginning to cause paint damage - I think some need to be removed completely up towards the bow and then the aft sets could be moved so that they are under the flat hull base 

despite religiously washing down after every trip! 

These just need to be moved completely inwards

Refurbishment could be around £500 if I get someone to do it and I replace all rollers and brackets, hubs and wheels. A new trailer is £1600 approx. 

Meanwhile the sailing season is sliding by. Serves me right - my head has been in motorhoming and house hunting not sailing and trailer maintenance. This is a very painful lesson to learn! 

Boat trailer woes

 It is easy to forget with a wooden boat that not all your time should be spent touching up boat dings and scratches. Trailers need TLC too. 😟

On our last trip out several weeks ago, Arwen's trailer lost a roller. I only noticed it when I went to retrieve the trailer from the top of the slipway to haul Arwen out of the water. One of the big blue and white wobble rollers had come off. 

You can see why I lost a roller. 

The washers have corroded badly and I haven't been diligent in trailer management.

In forlorn hope, I sprinted won the slipway to see if it had washed down in the tide and collected somewhere at the bottom in the little pool area, but sadly not. I searched the slipway and the patches of seaweed on it. Nothing.

Now I had a problem. The wobble roller arm was uneven and the empty bit was sticking up. There would be no way I could get Arwen back onto the trailer without that arm doing serious damage to her hull. I solved the problem by lashing it down tight, but this of course, elevated the other side of the arm. 

After hauling Arwen back onto the trailer, as I was flushing out the wheels, bearings and rollers with the slip way hose pipe, I took a closer look under her hull.

What a disaster. There was a deep scratch, no gouge, down her starboard side bottom plank. Clearly the roller had come off during the launch and the damage had been done. In my keenness to depart, I hadn't noticed! 😢

Back at home, I decided to try and put a spare roller back on. Stupid idea of course because the boat was still on the trailer but I'm slightly caught here because I'm worried if I launch Arwen again the wobble arm will do more damage! 

A deep concern. The torsional suspension stub hubs are completely corroded. More worrying is the the box section that the hub fits into (between rubber bungs) is also showing rust. 

Having jacked the trailer up and rested it in a stack of concrete blocks, I also took a look at the wheels. My worst suspicions were confirmed. Turn the wheel and it just rumbled. And, worse still, there was slight wobble play in the wheel on its hub and it wasn't anything to do with loose stud nuts. The wheel rims were showing signs of rust and flaky paint.  Below, Arwen's hull had some dings caused by pressure points where wood had rested awkwardly on rollers; there were worn streaks where the grey base paint was showing through and in places the top coat was flaking off as well. 

You can see the problem of these rollers. They are just not quite positioned correctly. 

The rear keel roller wasn't turning properly. The forward keel roller had shifted its position somehow. 

More concerning is when I reversed Arwen back up onto our sloping drive way, it took me 30 minutes to disengage the trailer hitch off the tow ball. It just wouldn't open and I had to reverse and move forward a few inches back and forth several times until it would disengage. First time this has happened! 😱

Trailer TLC - it is vital and this is a tough lesson to learn. The trailer is thirteen years old and I had it serviced two years ago. 

And I also noticed yesterday that one of the little black keel side rollers is also MIA

Arwen's trailer was never designed for her. It was an off the shelf one and the best I could find and afford at that time when we had other pressing family financial commitments. 

So, now it is decision time. Do I refurbish the trailer or invest in a new one?

Refurbishment:

• the galvanised trailer is pretty sound although where the hubs join is showing rust but I think it will clean up and is fairly secure
• new wheels rims and tyres
• new torsional suspension hubs, bearings and new rubber bungs
• two new keel rollers
• one new rear keel roller which better lines up and allows the bow to rise up onto the trailer
• convert it to bunks/skids - so two new skids
• will need to remove all the roller arms and wobble wheels
• will need to buy/borrow/hire an angle grinder because things have rusted on firmly!
• have limited space to do this - on a residential road which has a local small bus service
• will need to get Arwen off the trailer and secure somewhere for a day or two
• need to research how to change torsional stub hubs, how to renew trailer hub bearings and whether I can fit bearing buddies
• the one last issue is the rear keel roller is a bolted on one. The two roller support lugs are an integral part of the trailer frame, so I will need to angle grind these off 
• disadvantages of the current trailer - I have to dip the wheel bearings every time to get Arwen on and off the trailer
• advantages of current trailer - its rollers and one shove and she is off; once the bow is on the rear keel roller correctly, she is easy to winch on single handed

Buying a new trailer: 😕

• could get it customised to better fit Arwen's hull shape. (Her hull has slight rocker on it, what some would unkindly call a 'banana bottom'. Basically she has a flat middle to front section but the aft section rises slightly towards the transom as does the skeg).
• I'm not 100% sure but suspect, that bunks/skids would be better for this boat bottom than wobble rollers on arms. (It is a chine boat and so the rollers are difficult to get placed correctly). 
• possible things to consider
• break back design
• 8" or 10" wheels (8" ones would make the boat lower when launching?)
• using support bunks 
• several keel rollers to take the main weight of the boat
• lower winch post so that the bow sprit goes over the top
• a winch post with a groove in the rubber snubber so that the bobstay can be left on (is this possible?)* 
• metal wheel arches*
• meeting European trailer requirements
• sealed bearings or suitability for bearing buddies (even better AL-KO bearings?)
• better attachment of hubs to trailer via bolt plates
• adjustable skeg and bow keel rollers
• better lead on keel roller arrangement
• walkway*
• spare wheel holder*
• whole trailer cannot exceed 6m due to driveway restrictions
• galvanised or...?
• stainless steel fixings, bolts, nuts etc? 
• side guide poles*
• removable lighting board
• not a pressed steel hitch

*optional additions

My requirements for a trailer 😀

• easy to launch and retrieve in a variety of tidal and wind conditions, in differing water depths and on differing gradient ramps
• easy to tow long distances
• doesn't damage the hull
• can carry outboard on transom bracket in its upright, vertical position safely
• better quality bearings
• last another 20 years with a better annual maintenance regime imposed by me!!

So what weight does the trailer need to support? 

Oh my what a question to try and answer because truthfully I have no idea. 😟

I am guessing that Arwen empty but with masts, yard, boom and sails probably weighs 380lbs. I built the coamings slightly higher; I put in bigger coaming backs into the boat. I used sustainably source Brazilian mahogany for rub rails, centre case top and centre case area leading to mast slot.  Probably used far more epoxy than I needed to! John's website suggests 310lb.

When she is loaded up for a five day dinghy cruise, well then we have to consider lost. The two anchors with chain and rode probably weigh in around 40lbs or so. The outboard is around 40lbs or so. Galley boxes, spares, clothing, bedding, food, water, fuel, warps, anchor lines, safety gear; so much but never have I weighed it.

So summing up, I am reckoning that the boat fully laden with all gear will be somewhere around 500lbs+ 

So, I have been looking at un-braked trailers which will carry a laden weight between 280 - 350kgs. That surely must cover me with no problem at all. 

I have contacted several boat trailer manufacturers so far, giving them details of the issues, an article about John's navigator design (with dimensions, measurements and photos), details of the issues of my old trailer and my restrictions and potential trailer desires. 

Three have got back to me thinking they could do something. Two recommended bunks. One recommended rollers. two said ten inch wheels; one recommended 8 inch wheels. One said break back design; two don't offer that. 

All three warned me stocks are low given people went bonkers during the pandemic buying or building small boats! I could be waiting for several weeks if I order now! So delivery end of August at earliest.

I've listed websites and some of the trailers they have suggested could be adapted to meet needs. Most were recommended or mentioned to me by various members of the Dinghy Cruising Association.

 If you have any thoughts on any of them, please, please, please do drop me your advice in the comment box below.

So I finish this initial blog on a set of questions and a dilemma.

The questions:

1. refurbish existing trailer (cost around £400 if I do it myself; £700 if I get someone to do it for me) OR take the plunge and buy a new one better suited 
2. which are better for Arwen - bunks or rollers; 8" or 10" wheels; fixed or break back? 
3. material - galvanised, steel, aluminium? 
4. if bunks - what kind of bunk surface material is best? 

The dilemma:

The slipway I use is five miles away in the car. If I lash the roller arm back down, can I risk doing a few day launches with wheels where the hub bearings have gone? I've certainly done a few this year with the bearings in that state, but not realising it at the time. 

Phew! 

Forgive me Neptune, for I have sinned

 Forgive me King Neptune, for I have sinned. I did hire a motorboat when out on the broads!

We have been touring Norfolk and Suffolk in our motorhome Bryony. It has been our longest trip to date and we have spent a few days around Hickling Green and Hickling Broad. Most of the time we have been cycling but today we felt somewhat sore (having cycled over 150 miles in seven days) and so opted for a day on the water. 

SWMBO wasn't confident about hiring a day dinghy and when i saw what was on offer, neither was I to be fair. The little boats were barely water-worthy! So, we opted for an old motorboat with a diesel inboard engine. Hired from Whispering Boats at Hickling Green, we got a white painted plywood hulled boat with varnish rails and coamings. A bit dilapidated, with a patched hole in one corner, the varnish was peel in places and the screws rusting badly. The bow painter was blue knotted polypropylene string; the stern warps black 12mm plaited rope. It wasn't neglect but it was in need of some TLC. But then when people see Arwen they say the same thing, so who am I to judge?

Our intention was to spend four hours gently motoring across Hickling Broad and up through the cutaways into Horsey Mere before going up the river to Horsey Mill for a coffee and cake at the National Trust owned windmill. If there was time we would then head back down for a quick tour of Heigham Sound. 

The Whispering Boats yard is traditional; a few staithes with some permanent liveaboard boats alongside; some boats out of the water on hard standings; a narrow gently sloping ramp and a large corrugated boat building shed. Clean and organised it has an air of old fashioned competency about it; a place where apprentices once learned their craft from master boatbuilders. But now, trade isn't what it used to be. 

After a quick briefing, a warning about getting too close to the reed bed margins (clog the prop) and 'watch out for traditional sail boats coming around the bends' we were duly shown to our boat and left to our own devices. The first problem, how do you turn an 18' motor launch 90 degrees out of its stern to mooring in a staithe canal channel which is only 4' wider than the boat length; and with two other launches of identical dimensions moored gunwale to gunwale either side of you!

I should at this point, just in case you were all saying 'easy'......tell you that the steering was a steering wheel and then a wire and pulley affair to the rudder. A system so stiff, you physically had to yank the wheel one way or another. Think a steering wheel on a tank - non power assisted! 

Then throw in a throttle which was at best temperamental; stiff, unruly, prone to slipping and not holding its position! Truly hilarious. The only positive was the engine. Its regular chug chug beat and tempo just spoke reliability, trustworthiness, integrity. 

It took ten minutes to work out how to caress the throttle; a further ten minutes on how much effort to put into turning the wheel one way or the other to get some form of turn in the bow. Subtle steering it was not! Gauging speed wasn't an issue! There was slow, dead slow and stop!

Gently chugging out of the narrow yard entrance canal past moored boats of all descriptions and sizes, we entered between the first of over forty 12' tall square posts that marked the centre of the broad. Depth gauges on some of the posts suggested we had around 8' under us at the centre of the broad. With gentle breezes bow on, I was able to stand upright leaning on the top of the windshield with left hand on the steering wheel and right foot nudging the throttle down or up as required. A rather cavalier approach I am sure but given we had the whole broad to ourselves, I wasn't unduly worried. We were only doing 3 mph max. 

We passed flocks of swans cleaning themselves and shooing their broods of cygnets out of the way. Marsh harriers swooped above the reeds and out in the distance in a secluded corner of the broad, inaccessible to our boat an enormous bird of prey flew above the water in lazy circles. Was it an Osprey? It looked like one from a distance! 

At the yellow and black marker post we turned to port and started up the narrow channels that ran between marsh and reed bed islands. The channel was barely 20' wide and we were hemmed in by thick tall green reeds. Our horizon was those reeds punctuated by the odd oak tree or distant windmill. A closed world, a fascinating world, a gentle world.

Time slowed down, it practically stood still. The sun shone; the breeze whispered through the reeds. Reed buntings provided a sound track. A blue damselfly landed on my hand and stayed with me for twenty minutes up river. Ahead, huge dragonflies, the 'Gazelle helicopters' of the insect world buzzed and darted frantically across the water, skimming low and evading the sudden rises of Chub and Roach. Past motionless herons, their faces downward, peering in to the dark waters, waiting to rapier any small unsuspecting fish, we chugged along, our soundscape being enhanced by the repeated call of a distant cuckoo. 

You know when sail boats are approaching. You can see the tips of their masts and pennants streaming out at mastheads. Some are motoring, their masts devoid of sail. But then there are boats that are sailing, with acres of tan, cream or white sail clothing billowing in the breeze. Around the corners they creep, their booms invariably hung out over mid channel. In such circumstances, I found the easiest thing to do was to wait, throttle into neutral and then judicious use of forward, neutral and reverse gears to hold station as close to the reed margins as I dare, allowing them sufficient room to drift by silently. 

There is a grace and beauty to the traditional broad cruisers with their cream hulls and varnished topsides. You could get a suntan just from the reflection in that varnish work. 

Arriving at Horsey Mill staithe is tricky. Along the starboard side of the channel are private moorings. On the port side public tie up points. The channel between the moored boats either side is around 10' in width. The channel is a dead end with a right angled bend just before the mill. And, it is in the full glare of the public gaze, for this is a popular attraction. There is no place to hide. 

It is grown up pants time! You have to moor into the wind or the river flow, whichever is stronger. To try and moor going downwind or downflow is to invite disaster.  Today, I have to turn the boat in the channel for the wind has shifted to come from astern and its picked up! There is a 10' long gap between boats on each side. That is my turning point! 

Now, I do have Level 2 powerboat qualifications but frankly they are of bog all use here. It is an inboard with a temperamental throttle and antique steering system. The boss makes encouraging 'you've got this' noises. Her death grip hold on the coaming says it all really. She of little faith! 😆 

Its like doing a three point turn in a car only you are using a balance of reverse, forward and neutral in quick succession and, of course, you are turning the wheel counterintuitively at the same time as engaging reverse. It sounds more complicated than it is but unbelievably, and I do still have to pinch myself as I remember this, I actually did it. I turned a boat with only 1' surplus distance at each end of it and then bought it alongside a staithe without even bumping it; to a complete stop alongside a mooring ring. 

And I got a round of applause from some passerby's, walkers, who told me they had seen some horrendous foul ups on their walks along the various river channels. 

I didn't quite bow but internally I was jumping for joy. Boom, mic drop! 

Five minutes later and two experienced sailors managed to wedge their 20' cruiser with bow sprit in that right angled bend. I did get there before the impending disaster happened; I did plea with them to throw me a stern line so I could slow the boat and spin the stern around quickly. But they listened not and I was left to try and free their bowsprit, the bow sprit tackle and various other bits and pieces from the quayside ladder. The wire bobstay had dug itself  into one of the wooden staithes. That took a few minutes to retrieve! A husband and wife team, where the wife was the skipper, there had clearly been some disagreement on the best way to proceed as they made their final approach. 

Ah well, easily done and there but for the grace of God went I a few minutes before. And I didnt have their length or windage issues. It is an unforgiving sailing ground, these narrow broad's channels! 

At Heigham sound, we mooed up alongside a near empty staithe for a picnic and watched a couple tack their boat up the channel, gracefully and with confidence. A master class, even if their sail had that same familiar crease that Arwen's main sail has!!

Our return trip was serene with the same wildlife to see. Our arrival back at the yard was tricky. More boats had arrived and had moored directly opposite the turn into the little staithe we had to occupy. Moreover, two motorboats had occupied my space, leaving me right on the end. I didn't hit anything but it took three tries to get that boat in, turned at a right angle and stern moored onto the staithe. 

It pays to be humble and I'm glad I didnt gloat up at Horsey Mill. I learned a long time ago that it doesn't matter how good you think you are, how experienced or inexperienced you are - the water shows no mercy to those who don't show it due deference and respect.  

The arrival of my new telescope , the Skywatcher Discovery 150 i GOTO

 My new telescope finally arrived last week.  

Skywatcher Discovery 150i GOTO newtonian telescope

with SynScan app on smartphone to control its movement and access the database

Regular readers will know that I have taken up astrophotography and astronomy. My intention is to do them both when out on overnight up-river voyages in Arwen. There are one or two lovely, relatively dark sky, spots up the Lynher and Tamar and on gentle breeze days I might take either the Ioptron skytracker pro or the telescope with me. I am just working on how to safely keep them waterproofed and securely stored out of harm's way in Arwen. There again I might only take the skytracker as that is lightweight, small and portable.  (You can read about that by referring back a couple of posts). 

So, over the last few nights of clear skies I have been down to a local beach spot where the light pollution from the city is less. I can sit in the boot of the car, with the boot door raised above me and have telescope and ioptron tracker set up on tripods outside. 

It has, putting it mildly, been an interesting learning curve these last few nights. A good job I am a life time learning fan! Thus far, I have made some simple basic errors but had lots of fun and some good learning experiences:

• tripping over the tripods or knocking them when moving around - I am innately clumsy
• not getting the tripods level at the start
• not adjusting and calibrating my phone correctly so that the GOTO mount was out in its own tracking of stars and galaxies - that was a frustrating hour and a half trying to work out why the telescope pointed 90 degrees away from the object I had commanded it to GOTO 😕
• forgetting to set my phone to a red night setting, so every time I referred to one of the apps - it lit up bright white and ruined my night vision, which I had spent the last 30 minutes building up
• not calibrating the skytracker correctly so that the 200 x 2 minute photos I took were all out with elongated stars - that's over two hours of my life I won't get back again 😭
• watching the power cable from the powertank to the GOTO mount, wrap itself around the tripod as I made the telescope change various directions - that was a cable knot that took some sorting!
• not being able to set the camera and lens to the correct orientation because the first ball head mount I used was too small and unbeknown to me, kept slipping during the three hours that I tried to take photos with an intervalometer 😩. That was 400 photos into the digital waste bin! 
• trying to get my head around the various eyepieces and how to use them in conjunction with Barlow lenses
• trying to remember and recognise the key constellations and marker stars 

The skies above my back garden are too light polluted and also give restricted views of the night sky. Plenty of open skies facing north and nothing facing south due to the steeply wooded garden slope. 

Moon rise around 01.30 am over the river Yealm estuary

Last night my neighbours in the car park proved entertaining. For several hours they had a small BBQ between their two converted campervans. It was full of dancing orange flames and they sat around it singing, playing sitar music and the bongos and chanting. It got fairly wacky but chilled around 12.20am when one of them continually tried to get into their van without opening a door. When she passed out, I wasn't sure whether it was due to drink, concussion or the copious amounts of weed consumed. Either way, her companions carried her into the van and all seemed well. They put out the BBQ fire and everything was quiet for the rest of the night. 

Millennials eh? Such lightweights! In bed by 1.00 am!

So, one of the key things I am learning is that it is easier to get the images on the night and a damn sight harder to then process them in the software the next day! I am trying to master PIPP, Sequator, AutoStarkkert, Deep Sky Stacker and Affinity Photo. 

HUGE learning curve! 

No, seriously HUGE!!

So here are my first images using the ioptron skytracker pro. I haven't quite yet mastered how to use the DSLR on the telescope. That is next week's learning!

The Ioptron Skywatcher Pro

So, later this month, I will set out with the skytracker above and head up the local rivers for some sailing fun. I will beach each night and dry out and from above the high tide mark I will set up the new tripod, ioptron and camera and try to get some night sky shots. Hopefully some of the milky way above Arwen on a remote beach. But that involves taking two separate photographs, one of Arwen and the landscape and then a series of shots of the milky way, before creating a composite image.

And that is a whole new skill set to master! 

Its hard work this astrophotography malarkey! 

Rudder repaired

 The rudder is repaired and repainted. Time to go sailing again. Time to see if once and for all I can get to grips with proper seaman like sail trimming ...... Feels like such a dark art 😱. I just don't get why I don't understand how to do it properly.

So frustrating. 

The Ioptron Skytracker Pro

 As well as a telescope for my newly found hobbies of astronomy and astrophotography (which by the way still hasn’t arrived yet and I ordered it back at the start of January and its now May as I write this blog), I have just received an Ioptron skytracker Polar Pro.

Copyright: Ioptron

It is basically a compact, motorised one axis mount which precisely tracks the stars as they pass overhead of you. It has a maximum payload capacity of 6.6 pounds; weighs 2.5 lbs and is made of die-cast aluminium covered by ABS plastic. It has an internal battery (2000 mAh) which is rechargeable using a micro USB cable and it has 4 tracking speeds.

And when I mean compact, I really do mean compact. It fits in my hand and my camera bag with no problem.

Well packaged it arrives in a padded bag. It is a snug fit. I struggle to get it in and out but I guess that means it won’t shift around!

Unpacking the kit, I discovered the mount, an alt-azimuth base, a brass 3/8 and ¼ inch threaded ball head mount plate, a charging cable and the polar scope. People will also need a ball head to mount their camera to the tracker. I just used one I had off my Joby Gorillapod.

I’ve spent a couple of hours fiddling around with it working out how to set the latitude angle and also how to alter the horizontal plane as well and I think I have these worked out now. The polar scope has proved troublesome. This little scope has a scale reticule inside it which you use to line up the tracker with Polaris in the night sky. Sadly, my reticule seems to be a 90-degree angle to what it should be which does my head in when trying to do the simple alignment adjustments needed. I have contacted Rother Valley Optics and Ioptron to see if one of them can send me a new one.

Here is my problem. When the polar scope is correctly inserted into its holder as per the instruction manual, my reticule scale is not in the correct position. It is 90 degrees off to the left! 

I have yet to have a clear night where I can now get out and use it but I am assured by various astrophotography groups I subscribe to that I should now be able to take longer exposures of the night sky without any star trailing and that I should be able to capture images of distant nebulae and galaxies.

with the new tracker and some more on-line learning, I should be able to capture images like this using just my DSLR and the basic lenses. Above is the horsehead nebulae of Orion's belt and below the core of the Milky Way

I’m rather excited by this prospect. Anyway, the kit is coming with my Camera gear every time we now travel in Bryony (our motorhome) or Arwen (my 14’ cruising dinghy). I have the dark skies of Norfolk and North Wales beckoning me in the next few months along with planned voyages around the Fowey, Fal, Helford and Tamar rivers!

And now you can see why we have gone to the trouble of up-plating Bryony! It was the tow bar, the e bikes, the bike rack, the telescope and the camera gear wot did us in. Maggie would like to point out that when we recently went through all the stuff we could ditch out of Bryony, all she had that was her’s …. were her clothes and ………. a tiny 12v hair dryer!

I am still trying to live this down!

 

On Arwen, I haven’t yet decided whether to take the telescope in the boat. I am still trying how to keep it safe and waterproofed during a capsize. However, the tracker will come with me on each overnight trip now.

I will let you know how I get on with the tracker. This could be the start of a new interest group: ‘motorhoming astronomers!’

Clear skies, live long and prosper motorhoming buddies, and fair winds to all you sailors.

Steve

 

What are my initial impressions of the tracker?

Pros: Seems lightweight, portable, easy to put in camera rucksack. Fits on my standard photographic tripod. Has a good padded travel case. Construction seems solid. Well designed. Procedure to align tracker with Polaris seems straight forward from the videos I have watched thus far. Can be used in either northern or southern hemisphere – so will be taken on our future international travels as well. Easy to adjust. The associated app for locating Polaris works well. The motor is soundless, very impressive. There are four speeds – one for tracking night sky; one for night sky with landscape included; and two others for sun and moon tracking.

Cons: without the optional counterweight stem, then the payload is only 2.4lbs which is basically a DSLR and 50mm lens max so o telephoto lenses on it without the counterweight. Need to take all straps off your camera so they don’t catch the polar scope. Similarly make a little bag to hold your intervalometer so that it can be velcro’d to a tripod leg. That stops the cable from catching anything as the mount rotates.

If you would like to know more about how he tracker works, these videos should help

A much needed shake down cruise

 At last. It has been a long, long wait but finally, finally, I have been out on the water in Arwen.

The log details are simple enough:

• Force 3 winds with gusts to 17knots; SE around to SSW
• Low tide at 10.00am; high tide at 16.00pm
• passage plan: to sail across to Cremyll, just inside the entrance of the river Tamar and then back out into Plymouth Sound, with possible end of day trip up the river Plym before returning to Queen Ann's Battery marina. 

In a shake down cruise I would expect to do sailing on various points of wind, practise some reefing and heaving to, re-stow some of the onboard equipment and possibly practise using the anchor buddy by landing on a near by beach.

All that went out the window. The winds were perfect for just settling back and reaching back and fore across the sound. And why not?

So, I am baffled as to how I managed to take chunks out of my rudder! A mystery; but tomorrow is clearly going to be another 'repair' day! 

Ho hum!

First astronomy outings

 First astronomy outings

Funny old thing is life. Just as I was cursing my bad luck, a fortuitous stroke of good luck befell me. Regular blog readers will know I have ordered a telescope. I have taken up astronomy and the telescope will accompany us in Bryony our motorhome and onboard Arwen for some trips. You can read about the telescope and what I have been learning about amateur astronomy in previous blog posts or you can pop across to https://wherenexthun.blogspot.com for more detailed posts.

Anyway, said telescope was due at the end of February. Then it got delayed to the end of March. Then “It’s possible that it is on one of the crates on that ship in the Suez Canal”. Now it is due at the end of April! I’m not holding my breath on this one. A shortage of raw materials, a lack of workers, a shortage of shipping crates and uncertainty in supplies and back orders apparently.

So, the fortuitous good luck? Whilst browsing Facebook ‘market place’ for something entirely different, I “accidently” came across a table top, 4” Newtonian Dobsonian, beginner’s telescope in good condition; hardly used in fact.

I promptly checked out the prices of new ones and discovered that you couldn’t get one new for love nor money anywhere in the UK at this moment in time. Every telescope stockist known to man this side of the English Channel is ‘out of stock – awaiting new orders’.

And here was this one, barely used and just under half the price of a new one. By the time I had contacted the seller it was too late. He had someone coming to see it that morning. So disappointing; but imagine my glee when three hours later the seller contacted me to say the buyer hadn’t turned up. “Would you like to buy it?” Would I like to buy it? Would I….never mind!

It turns out that he hadn’t used it once. The little plastic insulator tab was still in the battery compartment. Brand new - what a stroke of luck.

And so, I have been out on two sessions under the stars putting into practice what I have learned so far. Which turned out to be nowhere near as much as I thought I had!

Session one was a shambles. I couldn’t find the stars or nebulae I was looking for. I couldn’t get the finderscope to work properly and I hadn’t aligned it correctly. A misaligned red dot finderscope on a telescope is a devious creationist thing of Satan! Let’s just leave it there shall we!

I dropped eyepieces in the dark. I kept leaving my red light on my headtorch on full beam. I couldn’t use higher magnification eyepieces because I kept losing the star I was looking at; don’t get me started on how to use a Barlow lens!

I tried to align the smartphone holder, in the dark. That’s an hour of my life I won’t get back again!

So much easier to align the smartphone holder in daylight!

You have to be a contortionist to use the finderscope. It has a red dot which seems to migrate within the viewfinder on its own accord. If the telescope is elevated at an angle of greater than 45 degrees, you have to virtually lie on the floor to be able to sight up the finderscope. They advertise it as a table top telescope for beginners. Are these beginners fairy folk?  You’d have to be the size of a barbie or action man to sight up this scope. Or you would need a table which is five feet high!

And then, just as you focus on something interesting, it moves out of view. So, you have to chase after it, only you have to remember that the image is upside down and reversed so the way you think you need to move the tube assembly is actually wrong, it’s the ‘other’ direction!

Meanwhile, to actually look down the eyepiece requires back breaking bends and after a few minutes, you can’t physically straighten. Throw in extreme cold, biting winds, stumbling around in the dark, a completely useless set of planetarium apps because you chose the only spot in your locality which doesn’t have any form of smart phone signal and hey it’s a challenging night!

And yes, I adored every minute of it! I am well and truly hooked.

Of course, it doesn’t help if you are trying to learn two separate things simultaneously. There is astrophotography – taking photographs of night landscapes and night skies; and there is astronomy – learning about the night sky and using a telescope to view night sky objects. Trying to learn both at the same time is …… courageous, challenging, stimulating …………. stupid!

But hey, being stupid, can sometimes be really, really fun can’t it!

PS: the photo below is the result of my second night session and I have outlined the details below.

“Last night was my first proper astrophotography session. I am trying to get to grips with two things - learning basic astronomy using a Newtonian telescope and astrophotography - using a DSLR camera and lens without a star tracker. I'm starting from a base of no knowledge whatsoever, but ever the lifelong learner..............

This is my first ever astro-photograph of a nebula. I took 300 photos of the general vicinity of the nebula as follows 1.3 sec,  300 images,  F/2.8,  ISO 1600,  200mm FL

No calibration frames and no star tracker.

I used the software program DeepSkyStacker for the very first time and then loaded the image up into Affinity Photo which is also new to me. I have never used Photoshop or Lightroom...so the learning curve has been steep to say the least.

This is my first effort. I will get better!

Messier 42, NGC 1976 - Great Orion Nebula - one of the brightest nebulae in the sky, one of the nearest star forming regions to our planet, Earth.  It is visible to the naked eye as a hazy patch surrounding the middle star of Orion's sword - Theta Orionis. The sword is just south of Orion's belt.

It is a diffuse emission nebula. If I were able to use a star tracker and longer exposure times, the nebula would appear redder and more violet-blue in colour. The greenish tint is caused by radiation from doubly ionized oxygen. It is 1350 light years away from us and is approximately 24 light years across in size. The youngest brightest stars within it are thought to be about 100,000 years old and emit large quantities of ionizing ultraviolet radiation, thus causing the nebula to glow by fluorescence.

There are approximately 700 stars in various stages of formation within this nebula.

Rubbish photo but what marvels of the multiverse there are to see if we take the time to look up occasionally”.
