My brother sails out of Sand Point, and he's noticed a couple of Daysailers stored there, but hasn't seen anyone active with them. Maybe you could probe around and see if you could get a little fleet going. The fleet here in Portland, OR is innactive, but I know there are must be local DS racers interested in getting back on the line! There must be more DS's in Seattle. It would be fun to have DS Regattas in Lake Washington!
Here's the site for Sand Point:

Good Luck!
