Greetings from Key West. I am currently in the proces of replacing my original Choey Lee mainsail with something a bit heavier and larger. My local sailmaker said after she studied the plans for the rig configuration that the sails made for the CD Typhoon (Weekender at least) were undersized and too light. I've opted for a new sail made to fit the rig a bit larger and at about 5.5 oz.
Does anyone have any similar mainsail stories, experiences, observations...and does anyone know why the default sail was made to underpower the rig? I mean, we are sailors, right?
Thanks!

Underpowered? Larger mainsail? I am curious...
Hmmm...underpowered...larger mainsail...
Being curious I have open in front of me the Typhoon weekender sailplan alongside of 'Sail Power' by Wallace Ross. No matter how I hold the pictures up, the sail size seems to be limited by the height of the mast and the length of the boom, yes? Now certainly sail construction has come a very long way from the Choey Lee design, but short of bringing the boom down to an unacceptable height I, for one, don't see how your sailmaker is going to get numbers much in excess of 22'-0" luff and 8'-9" foot. I have sailed with the original main, with a new loose footed main from Quantum, and with a full batten main from Sobstaad. The loose footed design was better in light air, but the full batten is anything but underpowered. Of course the roach is probably greater with the full battens, but the total footage carried can't be significantly different.
Just my thoughts of course.

huh?
uh, so you've tried a number of mains, is that right? are you a sailmaker? my point was that the original sail was undercut for the rig...which i still believe...and way too light (3.9 oz) to handle the breezes off Key West. but, being a know-it-all, you probably already knew that.

Re: Advice on new Typhoon mainsail
My Choey Lee's are cut short too, and I've been thinking this summer about replacing my vintage '74's with full battens (I sail Barnaget Bay, and spend most of my time close hauled or running almost dead downwind). This solution almost begs for a mast crane extension to lift the backstay further out from the mainsail. A welded stainless steel box bolted to the existing crane ought to do it. Perhaps your sailmaker might have an idea.
By the way, this would make it easier to run a genoea more of the time, which is the best cure for excessive wether helm.
As far as power goes, a boom vang would be the best thing you could do. Just flaten out the sail with the vang, ease the mainsheet and keep a constant speed in the chop. I learned that from "Sail Power" by Ross.
Let us know how you did.
