Could anyone steer me toward a good article or book on how to set up a fully battened una rig? I have sailed for decades coming through the RYA youth squads in Toppers, 420s and Lasers and then moved into Laser 4000's and RS400s but I have recently moved into singlehanders and this is the first time I have sailed a fully battened singlehander - seem to be struggling especially in the light wind stuff!

Thanks

Bethwaite is probably a good start. 2nd or 3rd book.

What boat are you sailing?
Make sure the leach is not closed in the light stuff. Have you adjusted the batten tension?

Sailing a Hadron H2, most of us are trying to work out how to set them up as they are new so I figured going back to basics might be a good place to start!

Ask the designer? He might just have an idea shirley?

Have they not given you a tuning guide.

I would guess when it's light use just enough of that kicker thing on to keep that great fat head closed but open to puffs (and ahem kinetic energy) When it's windy do everything you can to twist the f**ker open as far as you can, hopefully there's luff curve so a bunch of downhaul should do it.

Did I see on the fly rig raking to depower, thought I might have to help when it's windy.

But for the most part the sail looked like the sort of sail with plenty of auto response built in anyway in a just take out the creases kind of way, not that I've ever sailed it, but it just looked sort of OK if a tad on the large side for lil ole me.

There is a tuning guide but based on theory rather than practice as the boat is so new. I am trying to work out how to set up for light winds.

Can you recall the title - have Googled it but he did 4 books and not clear which is 2nd or 3rd due to the number of reprints etc!

Can you elaborate on battern tension and what to do in different winds?

Jim Hunt who I think designed the rig is usually very helpful but as a starting point have a look at the Solo trim guides. I guess the answer will be to make it as flat as possible with some twist in the light. Bethwaite is good but from memory he doesn't cover una rigs too well and not having a jib does make a difference - mainly that you need to trim the boom out 10-15degs or so and that also means getting a flat exit with a tight outhaul isn't as important ('cos you're sheeted out a bit and not on the centreline)

I very much doubt anything bethewaite has to say would have any relevance to an H2 rig, when it's light it's all about getting the rig to breath whilst retaining the ability to point. Therefore don't set the rig too full and play the kicker a bit until you can stuff it high yet still keep moving at an acceptable lick, is what I do, doesn't matter what boat it generally works on pretty much all of them.

Thanks! Called Jim and he is going to email me some stuff to help get started.
