water a couple of days the boat was filling with water, no aparent
holes in hull and still I was getting water inside sleep area days
after I pulled boat from water. if anybody has ever experienced
anything like this any help would be apreciated. thanks steve.

If you're making water when you're hauled out, and depending on

Look next for saturated flotation, and hope that isn't the case.
