drawback. Old-time New Haven sharpies used to have brails up the luff
to allow reefing that way.
I put reef points on my Cartoppers' sails. Same rig. They work great.
Obviously you'll need a halyard. Halyards add a lot of stress to a
mast. Bolger specifies mast dimensions for these rigs without
figuring in halyard stress. If you go the halyard route (and I've
sailed my Cartoppers reefed many, many times, with great enjoyment),
you'll want to dimension the mast a little bigger, or, rig up a jam
cleat at the mast head to relieve halyard stress. I use an open type
cleat mounted about 12" down from the masthead, in way of the
halyard. I hoist as usual, look up to make sure the halyard is in the
jam cleat, secure the downhaul, then I can let go the halyard and the
sail stays up. It works like a charm, and tremdously reduces mast
bend. When you want to douse sail, just pull the halyard away from
the mast, the jam cleat lets go, and down she comes.

Cut the foot dead straight. Cut some hollow in the leech to avoid
flutter. You do want draft, and a fair about of it because its a
catboat (no jib to help direct mainsail flow), so cut the luff about
3%-5% longer than the chord (horizantal dimension of the sail at any
given point). That number is gleaned from "The Sailmakers Apprentice"
by Emiliano Marino.
In higher winds tighten the snotter, the mast bends, and takes the
round out of the luff, flattening the sail and de-powering it.
Downwind in light air loosen the snotter and allow the sail to
billow, giving more power. In medium/high winds, downwind, tighten
the snotter to flatten sail and reduce/eliminate rythmic roll (a
scary thing). You might consider rigging up the snotter so you can
alter its verticle position. This gives you some additional leech
control. In lighter winds set it low on the mast, in higher winds set
it high. In real high winds set it lower (but not low) allowing the
leech to open and spilling some breeze, while yet allowing the
snotter to be kept tight, bending that mast (further de-powering).
I bought my sails, pre-cut but not assembled, from Sailrite, and have
been quite pleased with them (although I don't think they cut enough
draft into them).
Hope that helps.
