On my recently acquired DSI I have a hole in the longitudonal rib, the rib extending forward into the cuddy from the centerboard locker. The hole is about 3/4 to 1" and is on the port side of the rib.
What is the functional of this hole? It may drain the cockpit and cuddy, but to where? THe DSI has a cockpit drain but no separate bilge drain. Should this be plugged when underway? when on the trailer?
