Trisail use..

Why do you not use the boom to sheet off the trisail?
What's wrong with the boom?

You don't want the trisail to use the boom since the boom can be a deadly object with the force of a trisail attached to it. Most times, a trisail is sheeted in very tight and along the centerline of the boat, so there really isn't any need for a boom.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

A couple of years ago we had the occasion to hoist the trysail for the first time. We had a gale coming in 6-8 hours and decided to get it up and try it out various rigging methods before we needed it. One of the guys aboard (a very experienced sailor w/ >100,000 nm offshore) said the only way to go was with the clew lashed to the boom. As he had more experience w/ trysails than I we went with his suggestion. See the photo below for the result.

We sailed with it like this for several hours and as the wind velocity increased the big belly in the sail kept heeling us over. I thought the trim could be improved by bringing the sheet to a big snatch block on the leeward quarter and then to one of the cockpit winches. When we set the sail in this manner we were able to sheet it without the belly. The flatter sail performed much better -- less weather helm on the wheel, less heel.

It could be that some trysails can be cut so that they can be rigged to the boom. That wasn't the case with ours.
