The trimaran I linked earlier had a furling main with vertical battens and the sail area can be reduced as needed via furling.
triak sails page Interesting design ...
but the triak sail is only 40 square feet, 3.7 sq m
I need bigger ....
Can I make this ?
or have it made?
It's design sure looks like what i'd need.
And it would roll up and stow pretty easy.
I need more detailed pics and info on this .....
btw, the Raptor16 (and 17.5) is now out of business .....
