My Daysailor 3 takes on a huge amount of water in the bilge compartment. By the end of a sailing day, the bilge is completely filled with water. It takes about 30 minutes for all the water to drain from the boat. I've read before that this problem is very common with Daysailors and appears to be a basic design flaw relating to the centerboard housing.Does anyone have some DETAILED information on how to remedy this problem? Thanks.Steve T.
