So here I was musing “
what would happen if I removed the battens from Arwen’s mainsail?”
Dear Lord have mercy: wot is this man trying to do to that mainsail?
Well not being the most technically alert sailor, I honestly had no idea. I know the mainsail can be a pain to drop and stow without the battens having a life of their own....but exactly how crucial are they?
Well, only one bunch of guys to ask really.......and so over to the JW forum I went.
“I would try it and see. Your biggest problem might be the leach will fall off and you will lose power as your effective sail area is reduced”
Had to remind myself which part of the sail the leech was (pitiful isn’t it – sorry guys!)
“Theoretically better performance in light air; less control. Shouldn't be hard to try out...”
(Unless you are an idiot like me – then it can be easily complicated).
“Steve, there has been an update in the rig plan for Navigator, the top battens have been shortened at the forward end to make the sail easier to stow, take 120mm off forward end of the top one, and 200mm off the next one down. You should be able to hand stitch the ends of the batten pockets to do that, and it’s not a problem to shorten the batten itself with a hacksaw and file”.
Wow! Hack at the battens........I’m a tea totaller but that sounds like seriously straying into ‘have a double scotch before embarking on that course of action to stiffen the spine’ kind of territory! However........it did come from JW himself....so that’s OK with me. But hang on.....a vague memory is appearing. I'm sure Chris jeckells decided to do that unilaterally when he mad eup the sails............I think!
Don't bother asking: it didn't work...hardly surprising really!
The word 'shambolic' is the politest I can use here
“I tried removing them all once just to see what would happen. Didn't work. The sail folds and flops over along a line from head to clew”.
Hang on – head and clew, where is my ‘dinghy sailing for dummies’ book?
“I think the reason your sail only bulges a bit when stowed is because your batten pockets are set at more of a vertical angle than mine. Mine are set more horizontally. Consequently, I have to pull my battens about half way out of the pockets every time I furl, which I want to avoid. Otherwise they're in my face or at a risk of snapping in half. Longer battens are generally better for sail shape, so since yours is working I'd be hesitant to mess with it too”.
Ha, a good observation!
“Next time I'm out I plan on trying John's shortened batten suggestion, and experiment with other lengths, and I'll report back with the results. Looking over my Navigator photo collection, I'm encouraged to see many mainsails without any full length battens at all, and they have beautiful sail shapes too”.
Generous offer – thank you!
“My goal is to "have my cake and eat it too". I want to keep that beautiful sail shape but also be able to drop the main right into my lazyjacks without having to touch the battens or anything else on the sail and without leaving my seat”.
Now see – here is someone who understands me completely – that is exactly what I want and can’t seem to get!
“My full length battens do bulge a bit when stowed on the boom, and I'll consider shortening as John has suggested, but I just want to say how pleased I am with my Duckworks sails, and how much pleasure that main sail has given me, both in performance and appearance. My youngest son often says (as he lays back in the cockpit looking upwards) that the shape of the main reminds him of the shape of Spitfire fighter wing. And the battens as originally designed give beautiful sail shape whatever wind there is (or not). So I hesitate to change a thing”
Now this is a person who knows a thing or two about design and how to sail – so I’m supposed to be getting a spitfire wing shape to the mainsail.........ah........now that is something to aim for!
“I think it was Kevin (navigator Slipjig) who had the clever idea of tensioning the yard luff with a short line though a cleat at the yard peak. When the sail is dropped the tension can be removed and the battens can lie more easily. It is a two-step process though so would not suit you”
Yeah – I think that’s a great idea but is probably, in all truth, beyond my technical ability, patience or understanding. It's spooky how well these guys know me!
stupid fixed grin says it all really
Not the brightest card in the pack!
Robin, Rob, Hajo, Joel, Alan and JW........thank you and sorry for asking such a dumb question in the first place! On the other hand, as I always say to my students...there is never anything like a dumb question.......if you don’t know, you don’t know and that’s the fun in learning....finding it out!
