Man, must be a heck of a rain storm! I had the common C25 (and others) problem of water leaking through the anchor locker around the drain tube into my v-berth area. It was a simple matter of sealing around the tube inside the locker.As far as water not draining out fast enough, just use a coat hanger to poke through the drain tube and make sure it's not clogged. Also, replace the weatherstripping around the locker hatch to reduce the amount of water getting in. (Note that I said REDUCE, you'll never stop it all!)Jack
