I doubt the wing would perform well on an IOM hull, due to the heeling and the lead hanging. IMO, It would (and does!) excel on a multihull for those same reasons. All of the lift is going into forward motion instead of heeling, and without the drag of extra weight in the water, the boat speed/apparent wind/acceleration would be higher.

The waterline wouldn't be good, but try taking the lead off of your IOM hull, strap a couple of carbon tubes across the deck and add two amas to them. Presto, a poor man's tri!

That was the concept of the MultiONE class here in the US - easy to try multihulls, although center hull is much too "fat" to be competitive against a "purpose-built" multi.

I don't know if I'm an expert in anything, but I do use an arm winch. I use the Hitech HS-7950TG It is a standard size, and fairly light weight (68g), but with 403/486 oz/in of torque at 6v/7.4v. The transit time is sooo quick compared to a drum winch. Want to jibe? Head down a little, flick the sails in then out (.13sec/60*), and the sails will go across very fast! My 1:2 purchase sail arm is 3" from center of shaft to center of block, to get enough travel.

There are several similar models with less torque and a lower price. I wouldn't get much below 300oz/in torque if you still want enough pull when the wind gets up.

Now if they will only make a small rudder servo that is rated for 7.4v, we'll be set! I use a voltage regulator to knock mine down to 6v just for the rudder. I have to rewire my boat, till then, so the sail servo will use the whole 7.2V that my A123 cells are putting out, instead of the 6v from the regulator.

I am missing the Blow Out regatta in Dallas this weekend, where it is supposed to blow the dog off the chain this weekend! The US IOM webpage should have updates. http://onemetre.sbmyc.com/forums/

Hew,
I run a Mini servo (bought of Ebay for about AUD$15 metal gears works great) as a rudder servo and 2 x A123 cells also my winch is a Hitec drum type and i don't use a voltage regulator.

Thanks Mike,
Personal goal was a top half of the fleet finish,so am fairly happy with that placing although there are 5 or 6 or 7....mistakes that I made,pretty dumb ones too ,that had I avoided a better place may have been possible.
Over all the event was excellent and 99.9% of people had fun and left in a positive frame of mind and smiling,so we are calling it a success.
As jteo has posted,that site gives some good photos of the site and sailing,thanks to Graham for his efforts.
DM1,DM2 are both designs out of the KEVIN DIBLEY business.He designs very competitive big boats,and so it seems small as well. Boats 82 and 64 are DM2s and boat 124 is a DM1

Further to the DM1 and 2's
These are nearly impossible to get.The design is owned by one of the DM2 sailors and they are built by another owner.Second hand ones do come up for sale very occasionally but if you hesitate in saying yes to a sale offer you will miss out.DM1 boat 124 was on offer last year after the Auckland champs,I thought about it for a week and when I rang back about it,a sale had already happened and the old owner was thinking he sold to cheap because he was being swamped with offers.
