You would have a better idea than me, needs a couple of knowledgeable sailors to test it, over a couple of days, new wings make it so easy to sail even in strong winds, you can reach past a Laser sitting up, Laser helm is out on his toes.

What we need to do is get together again and test your theories!

Rupert,
I have found Sail pretty much works with settings used by Laser sailors, especially round our small lake, haven't tried it on long reaches etc, you would get more of a feel of what is happening.
Beating and running, I set it tight enough so you can get your fist between sail and boom.
The problem is it's an untested design, theirs no data from when it was first used, controls on my boat also substantially more powerful than original, larger stiffer boom, centre main instead of off the boom or aft main, wings instead of sliding seat.

With such a long boom, things are a little more complex than that to get the most out of a Minisail or Sprint. Outhaul is totally wind strength dependent. In a blow upwind, it will be tight enough to be right on the boom. As the wind drops, shape needs to be created, as the wind isn't doing it for you. I set reaching very much by feel, cracking off a little to create as much fullness as I happen to want at the time. Running, I really don't want a totally flat sail, I just don't want to lose masses of area. Probably set a little like a lightish wind beat, in, but no creases.

Centreboard, adjust unless the time spent adjusting isn't worth the concentration lapse, which would be roughly what you said, 4320.

Colprice, yes, moving is a deadly sin! Spreading by the weight sideways, but as close as possible fire and aft, pulling the mainsheet in and clenching ones buttocks also helps!

The other point is that raising a centreboard will shift the centre of lateral resistance.
To turn a dinghy downwind, raise the centreboard (pivot the blade backwards) and it's easy to turn downwind as well as acting more like a long keel design.

Just for Rupert - we used to reduce the Firefly death roll by having the crew sit out to leeward, helm to windward and not, emphatically not, to move body position. Ie don't try to keep body upright, roll with the boat. Also, don't try go correct the roll with the rudder! This increased to moment of inertia sufficiently to increase the period of the roll and make it less deadly. Techique was used with the old spoon rudder...

Lifting a centreboard 2/3 up also increases longitudinal stability, which seems to stop the boat from broaching or rolling too much on the run. Firefly death rolls are scary things. Board up too much, and there is too little resistance to the roll, too vertical and the balance is all wrong and a broaching she will go. In very light winds, 3/4 up will be ok.

To be fair that is one of the most common mistakes by club laser sailors that they lift the daggerboard to high on a run

The shape of the hull also makes a difference, leaving the board down in an Ent on a run is a capsize waiting to happen if there's any wind. Half  board on reaches and fully up on runs was what I was taught. Of course it's hard to ruin the profile of an Ent foil more than it is by design  Wink

The Spice copes well with full board until you're getting overpowered so I generally set it for the wind strength and leave it unless it changes.
