Question about build structure of M17
Hello, due to a silly mistake on my part (I disconnected the sink drain pipe before the winter, and forgot to reconnect it before going sailing) I ended up with the cabin submerged under about four inches of lake water in my 1982 galley model M-17. After a lot of work I managed to drain it all out; from what I can see there is no more water anywhere (looking towards the back, under the benches, and/or forward towards the bow in the area under the sleeping quarters, where the water tank and battery are). However, the following very annoying thing happens: if I drive the boat around for even 5 minutes, water starts collecting in front of the wall separating the storage compartment at the bow from the main cabin (the little wall where the main electrical switches are). And not just a little bit: after thinking that the boat was completely dry, yesterday I took a quarter of a bucket of water out. The water that comes out looks reasonably clean. This makes me think that there is still a large stash of water hiding somewhere where I can't see or reach it. Any ideas where it might be? Perhaps Jerry can chime in, knowing all the nooks and crannies of the boat? My best guess would be that the water hides in the space between the main hull and under the cabin sole; but for what I was able to see these two form a watertight compartment. Is that true? If not, how can I reach that space? I don't want water to stay in the boat and start creating mold, and surely I don't want my main storage area to get wet every time I drive... Thanks for any suggestions. Andrei.
Audasea is a 1978 galley model, so there should be some similarity. I can't think of anyplace for water to hide. It's the basic hull, onto which was placed the cabin molding, which consists of port cockpit locker, open space in front of that (which drains into cabin) and forward of that is the galley itself (assuming you mopped up all water below it). Down the starboard side is the starboard bunk, which would be wet and which might be pocketing a quart of so of water, but not much. Forward of that is the bow storage locker. No other dead spaces, except for possibly a bilge, but you could see that. On several occasions, I've cleared the boat out and gone at it on the inside with garden hoses, power washers, etc. Several inches of water inside the boat. Never had any leftovers once I pumped it all out and mopped up the pockets. BTW, once it gets wet, the carpet under the starboard bunk takes forever to dry out. A fan helps. Are you sure you are not leaking a little from the sink drain / hose? On Apr 27, 2009, at 8:58 AM, Andrei Caldararu wrote:

Hi Howard, the port cockpit locker, the galley, the main cabin and the area under the starboard bunk are all bone dry. There is a small bilge behind the centerboard trunk, but I emptied that one out (it still collected maybe one cupful of water after driving around, but that's probably just stuff left around). I don't have any carpet under the starboard bunk. It is the bow storage locker that causes the trouble. Could there be water hiding either under the water tank support or under the battery support (both have some kind of pedestal they sit on)? My bigger worry would be if water got somehow in the space between the cabin molding and the hull, and is trapped there. Or could there be water in the main keel trunk? Obviously that would lead to the steel punchings rusting, not good... However, the water that appears being rather clean makes me think it's probably not from the ballast area. I found no way to access either of these spaces. I did try to tilt the boat with its trailer as far back as it would go (maybe 30 degrees angle). It stayed like that for 10 minutes, and upon returning it to a flat position not much water showed up. Andrei.
I have a 1977 galley model M17. When we first got the boat there was evidence of water in between the hull liner and the hull. The previous owner had holes drilled and had started cutting around the keel trunk. http://www.fafnirnet.net/gallery2/main.php?g2_itemId=218 I eventually tracked my problem down to water leaking in at the keel stop bolt and pivot bolt. I suspect water has found a way to get in between the hull and hull liner. If it were me, I would drill a small hole in your hull liner (always hard to drill holes in a boat) and using a shop vac suck out what you can. Then either fill in the hole or else screw something into the hole with an O ring after things have dried out. Good luck, Chad On Apr 27, 2009, at 9:45 AM, Andrei Caldararu wrote:

I have had an alternative idea to drilling holes, but I don't know if it'll work -- what do you think: there is an inspection port (round, about 3-4 inches in diameter) at the front of the sleeping area. I assume that through it I may be able to access the space between the hull and the liner? I was thinking of tilting the boat with its bow way down (by driving down a steep hill) and using a plastic tube to siphon whatever water collects there. Andrei.
If you can access the space between the hull and hull liner through the inspection port then you are good. You can try the sloping down hill method, but that may not work. Perhaps the water is able to exit the space when you are going uphill and then only collects in the lowest spot which appears to be under your V birth. The nice thing about getting shop vac going is as you are sucking air out, you are also pulling air in (more then likely through where ever the water came in at) which will really help dry things out quickly. --Chad On Apr 27, 2009, at 10:48 AM, Andrei Caldararu wrote:

Assuming you had no water entering before you left the hose off, perhaps you can assume that all water is leftover from "the incident"? That being the case, it's going to quickly go away. If water keeps showing up, you have another problem and the hunt starts. Time will tell.
