I've got a custom steel
34 foot cutter
that came with a twizzle sail, also known as a "butterfly" sail. I used it a few times and believe it would excellent for long term downwind sailing in the trades. Incidentally, you can lap one half of the sail over the other and use it as a jib
(though a heavy one). It was rigged as a roller furling
has three head sails
; sort of a solent rig with a staysail. I ended up removing the twizzle and putting on a light air 135 percent genoa
on the forward most head
stay. On the next head
stay I've got a high cut jib
that is about ninety percent. The innermost stay is for the stay sail and that is a hanked on sail. I also have a storm jib
that can be put on that stay. Besides the weight issues of having three head sails
, the only other negative aspect is that I have to roll up the genoa
when I tack: there is only about 18 inches between the genoa and jib headstays.
I've done some downwind sailing with both the genoa and jib poled out and it seems to work
fine, so the twizzle was a superfluous sail. Want to buy it?
