I've seen (and considered) several mainsheet variations on the P-15 - some at
the end of the boom and some of the "headknocker" variety (pivoting block and
cleat mounted on the boom). Since you lose that part of the purchase that
pulls more or less straight down into the cockpit, to control twist in the
sail you need to add a boom vang. Even if you don't move your mainsheet, a
vang can improve performance when going downwind. It's not necessary to buy
one of the commercially prepared ones, the stress on the Potter rig is so low
you can build one for less money with lighter parts. Contact me if you'd like
details, part #s etc.
I have no experience with lazy jacks, but they sound like a useful idea. I'd
be interested in hearing what you learn about them from others.

1) Potter 15 Boom end sheeting: What are the benefits, disadvantages,
of removing the block from the cockpit? How does this affect stress on
the boom and sail shape? Are there drawings and descriptions of how to
do it and equipment/Hardware needed?
2) Potter 15 Lazy Jacks: Does anyone know of a guide on how to build
these with drawings? I love to "Do it myself" and have the time and
tools if I could get an idea of how they are supposed to look and work.
Thanks - and Fair Winds!
