For many moons I wondered how my H17 was taking on water. I even went to every wing plug and dumped a cup of water in there, waited 6 hours to see if any had leaked into the hulls... when none had I was furious...

then I found out that there are breather holes in my hull where the front crossbeam attaches to the hull that sometimes let water in. I've come to accept the fact that my boat will have some water in it when I'm finished sailing for the day.
