Karl,

Don't feel dumb. You wouldn't believe some of the questions I get asked in the store!!

Wear your drysuit like you would a wetsuit, underneath your harness and PFD. Generally, your PFD on top of all, though some people do prefer to wear their harness over their PFD. Some people like to sail McGregor's too <img src="http://www.catsailor.com/forums/images/graemlins/smile.gif" alt="" />

Personally, I think the new Gul Code Zero Drysuit is the cat's pajamas. Breathable, dynat zipper, glideskin seals, trim fit made possible with the use of stretch panels. Check it out at www.gul.com. I'm pretty sure that the CatHouse has them, not sure who else in your neck of the woods. You could always pick one up at the FX-1 NAs in BC. <img src="http://www.catsailor.com/forums/images/graemlins/ooo.gif" alt="" /> (You'll want one on Harrison Lake)
