I discovered about 1.5" of water (kinda long)
this last weekend in both the port and starboard settees (sp?). We just launched on Saturday. I had the same problem last season and found two things that I thought fixed the problem but apparently did not. 1) make SURE the plug on the ballast tank is sealed GOOD. Hold onto the black rubber part and screw the handle down to make the plug as fat as possible to fit into the hole and flip down the handle. 2) make sure that the large bolt head under the table in the compression post plate is completely sealed. I put a large wad of 5200 on that cause it had NONE. I also sealed around where the compression post sits on/in the plate. Thought I had it fixed until this last weekend. Not to mention that when we put in I made sure to observe/control the amount of water that was let into the ballast tank. Last year I didn't do that and it was full to the brim so that I could not put any treatment into the tank.Anyway on Monday we tore everything apart to look for a leak. I even took off the little plate in the forward V-berth to check the fresh water fill/vent and the anchor locker drain. I could take 2-3 turns on every hose clamp and I also worked over the anchor locker drain and re-caulked it as good as I could in that tiny space. I could not see/get to the clamp on the water fill hose, so I removed the filler cap screws and pried it off the deck to find that I STILL could not get to the clamp cause it would not come up through the hole cause the clamp was in the way! Man! I must mention However that the area under the V-berth where the water tank (and my two batteries) are located was dry, thank goodness. Upon inspecting the compression post area again I discovered what appeared to be a leak around the post plate itself! Seems that the factory seal there was again insufficient. Since the area was wet and not exactly clean I thought that 5200 fast set would not work. A freind brought over what was a "stick" of two part epoxy that he said he thought he got at a Schucks auto parts store. It said it was for use in wet applications for repairing tanks etc. and I now believe you could even use this stuff underwater! You break off a chunk and knead it to mix the two parts together and you end up with a putty like substance. I pushed it into every crevice I could find/reach around the post plate. Then we had to come home. Next weekend I'll check it and, if need be, do it some more. I am feeling good that this may be a solution. It is VERY annoying/frustrating the discover all your stored stuff, food, clothes, you name it, ruined or at least thoroughly soaked and possibly destroyed. I have not checked under the aft berth but under the galley and the head cabinets I think it was dry, but I'll check again.Good luck.Tom M.
