Hi Guys

What you said about it being easy to oversheet a square top sail seems to contradict Gary's experience with his Ashby main (square compared to his previous Irwin sail). [/quote]

I'd have to agree here. I've been sailing Dolphins for 30 years, and the last 15 has been with a square topped main, teamed with a wing mast.

I use enormous mainsheet tension to keep the top from laying off. I'd have thought that the mozzie mast would be too soft for a square top, in that it would keep bending whilst more mainsheet is applied. This is where the reverse diamonds up the top would be needed.

Cheers
