Dinghy cruising: Fine tuning the standing lug rig - an update

Well, progress is being made. A video is on its way showing some of the subtle differences I have managed to achieve in rigging and sail shape. There is still a way to go but we are getting there, thanks to the help of John, Joel, my good friend Dave and many others out there in the FaceBook community. The Jedi side of FaceBook as I like to think of it.

A quick trip out in the sound last week and another quick trip to Salcombe yesterday tested out some of the rig adjustments.


The moving of the mainsail peak right to the top of the aft part of the yard has let to better upper sail shape although please don't as me to explain why - as I have not the foggiest idea.

The new arrangement of an S hook onto which I can attach the parrel bead loop at the tack of the sail is much better although I suspect I am going to have to move the main mast side cleat position.

The loop keeps getting caught on it as I haul up the main sail and so the sail is being prevented from reaching its highest point on the mast as it should. In the interim, I haul the main sail up and then move forward to attach the parrel loop but it is a pain and unnecessary, so the cleat will have to be moved.

The moving of the tack downhaul has been a great success but has more work to do on it. The tack is now held against the base of the mast, much better! The tack downhaul is now a line which runs down through the deck from the tack S hook and attaches to the block and tackle which lies in front of the centrecase.  It is here that the problem exists. I still cant get sufficient tension on the luff to eliminate the throat to clew crease before the two blocks in the tackle end up meeting each other.  similarly, the line from tackle to tack is a little too short an so restricts the height I can pull the main sail up (by a few inches).



So, tomorrow I will alter the block and tackle positions allowing a greater distance between them and I will alter the length of the line. Next week I will get out again and quickly test them one more time. I am hoping these adjustments will be the final ones and the crease will disappear for good.

The new arrangement for holding the yard against the mast is much better and the steel loops on the yard with the mainsail halyard going through the top one, then around the port side of the mast to tie off on the lower one seem to be doing the trick. I think some further adjustment is needed but I haven't yet quite worked out what it is. I'll get there. I am what some might term a slow learner!



What is definite is that in light winds yesterday at Salcombe, Arwen sailed better than she has in the past. This may be down to the alterations. It may be down to my greater understanding of the rig, developed over this last year or so.


I am going to remove the reefing lines and set them up as I saw Tim do on Facebook. He kindly sent me some photographs of his arrangement, in which he has a line with a hook attached to the aft end of the sprit boom which he can clip onto the first or second reefing cringle in the leech of the main sail. I guess the line with clip is just held in place by a velcro loop when not in use. Similarly at the tack end, he has another short line with another hook that runs from the downhaul hook and this clips into either of the reefing cringles on the luff.  It looks much easier and neater than my current system and is worth a try.

And that is it. Over the winter I will paint the hull again as the trailer rollers have taken their toll. The rub rails need a good sanding and filling in places, there are signs of rot in one or two patches. I will put in new circular hatches on the front thwart seat tops and fill in the hatch openings on the thwart sides. that will make those locker spaces far more accessible.  Little locks have been installed on all hatch lids already so that if I am camp cruising and go off for a stroll it will potentially slow down or hopefully deter any pilfering light-fingered groats!

I enjoyed sailing in Salcombe yesterday. It was far less busy with plenty of space to tack and drift without being mown down by someone. Much better!  Now if only I can find a tide which will be suitable for a bit of camp cruising up the creeks to Frogmore, Southpool and Kingsbridge.

  1. Steve, my ignorance is at least as scary as yours.......so no advice here, however, I'm a blacksmith And a bit local, so, if you want rigging bits.....just ask
    Good wishes,

  2. Matt, that is a kind offer and one I will bear in mind as i continue to re-rig Arwen. Are you a local sailor as well?

  3. Yes, trying to fathom out how to get a dipping lug to sail on the Fowey. Sometimes a new hook or traveller is needed to answer the question would it work better if....

  4. actually that's my alternative if i cant get this to work properly - a sort of traveller ring affair with a hook on that attaches to the stainless steel loop on the top yard and haul it up that way. how big is your boat?
