My trusty 22 is taking on water under sail. This started last year. Taking on about 2 gallons per hour under moderate stress. Medium to high wind conditions. This year it is worse taking on 2 to 4 gallons per hour even with slight wind. My only through the hull fitting is for the sink. This seems fine. I seldon heel up far enough to have waves hitting the gunwale. I am stumped by this. She takes on no water at the dock.
