Here is part of an e-mail I sent to Bob Curry yesterday:

Since this is a development class, limiting mast height is going to be a constant problem, because there are so many ways to hang a sail. What would you do about gaff rigs? Isn't the gaff, in effect, like a super-bendy extension of the mast? And what about lateen rigs? And what about the style of rig on the Aqua Cats, that do not have a traditional type of mast at all?

When I started thinking about it, I realized that the mere fact of limiting the height of the mast is actually limiting creativity because it implies that a mast is one straight stick.

What if somebody wants to try putting a mast on each hull, a la Ives Parlier? Or strap a couple of sailboards together? Or use an arch mast or a tripod?

The more open the rules, the more my imagination goes wild with ideas to try.

Why mention the word "mast" at all? Why stifle creativity? Maybe it should just be sail area, period, and you hang it up there with a sky hook, if you can.
