In fact, that's why it is so immediately apparent that there is water in there -- because the moment you step on it you can hear and feel the water sloshing inside -- kind of like a little waterbed. Are you saying that water may have actually seeped through from the inside of the cabin, through small cracks in the floor? It is true enough that this boat was kept, at least for the last year, outside in the elements. (Covered by a tarp but still.) If there IS a leak I'd like to find it this winter so I don't lose any sailing time next season. OK, here's the question for ALL you experienced M15ers out there: do I just pump out what's in there now and wait and see what happens when I put her in the water next season? Or do I perform the dreaded "fill-up-the-hull-with-water test" as soon as possible? PS: OK, Stan, point taken. My lovely bride does have a name. It's 'Debra' and she's kind of shy, so go easy on her.
