Another method is to have 2 sets of
foul weather gear. We do this to save $$ and of course
washing. The first set gets us through really nasty weather and allows us to
head to the slopes for a day of snowboarding or cross country skiing. The second set is for when it's hot and rainy and you aren't so how that you enjoy being wet. Second set is also for 3 mile
dinghy rides in 4' chop. We wear them on sunny days too, to aviod being hosed by salt water.
First set: Expedition type North Face waterproof ski jacket with
hood and matching waterproof pants. With these, you can pilot the
boat in sub zero (degrees C) temps and be warm and dry as you wish in rain, snow, sleet, etc...
Second set: $30 vinyl "bright yellow" raingear from West
Marine with vents, but not breathable. To clean salt off, wear ashore one day while it's raining. If they get too funky, buy another set. They're $30.
