Watertight, my foot!

gegcarter@... #14667 Joel accurately described the factors behind the failure of the ‘watertight’ bulkhead between the forward accommodation and the saloon: whether owing to builder oversight, modification or age, the space between the conduit trunking and the pipes taking water for heads, a/c and anchor wash is not filled. In our case this is visible from forward under the lower shelf beneath the holding tank. We were made aware of the issue only because we a) had failed to check the tightness of the bowthruster cables, b) were heeled to port at 20-30 degrees for 48 hours as we crossed the Bay of Biscay fine reaching on starboard in 25-35kt winds and a biggish sea c) slamming frequently. a) and c) meant the bowthruster leaked prodigiously and b) that the collected water crossed the watertight bulkhead through the pipe trunkings. It became visible in the central stowage (saloon and forward cabin) only when the boat came upright on arrival in Gijon. I suppose that the purpose of this site is for us to learn from one another’s experiences. In this case people with boats answering Joel’s description should probably check their bulkheads. Like Mahili, we fixed the problem – we used closed cell foam. And check your bowthruster before making a big trip!

I cannot imagine how this is happening to you, unless that drain hose has been moved from its original position, or your bow is down about 25-30cm. Is the drain hose in the bottom of each saloon locker? You might try pouring 1-2 liter of colored water into the shower drain and have someone watch at the sump to see if it drains and it is colored. Possibly there is an obstruction in the hose. Please explain further...I am always a little slow on understanding something new.

Alan Leslie #14761 Sorry for the late reply Kent / Bill...we've been at sea for the last week...great trip by the way...Noumea to Opua. YES that's exactly what happens.....going to windward in heavy seas on st'bd tack is when we see it, so it must be coming from the chain locker....that's why I'm going to put an extra valve in the drain from the fwd head...ie the head will be isolated but the chain locker can still drain into the sump. thanks for your input Cheers Alan S.V.Elyse SM437 ---In amelyachtowners@..., <gegcarter@...> wrote: Joel accurately described the factors behind the failure of the ‘watertight’ bulkhead between the forward accommodation and the saloon: whether owing to builder oversight, modification or age, the space between the conduit trunking and the pipes taking water for heads, a/c and anchor wash is not filled.
