Both these stories would seem to suggest bilge hose discharge ports low on the boats' transoms - is that true? If so that would seem a slightly risky location for discharge ports, as the stories bear out. In that situation is it possible to change the location of the discharge port, as in cut a new hole for a through-hull high up on the boat's quarter, and patch the old hole on the boat's transom?

A fellow club member with a C&C 41 was doing a trip from Halifax, N.S. to St. John's, Newfoundland.....at 2 a.m. an off-watch crew member heard the electric bilge pump running and wouldn't stop....the water kept coming into the bilge and they didn't know where it was coming from.....all hands are now awake searching every possible thru hull, valve, etc looking for the source of the water....no luck and they are getting very nervous.....everyone puts on a PFD and the life raft is untied just in case. There is a following sea....finally one of the crew realizes the water is coming in from the hose of the manual pump.....with the following sea, the water started siphoning into the boat through the manual bilge pump hose. They cut the hose where it runs aft in the lazaret and put a wooden plug is the back end. No more manual bilge pump for the rest of the voyage but it didn't bother them.....they were now safe.....that was a bit of excitement in the middle of the night. I had a similar setup for the manual bilge pump hose on my 32, however, after I heard their story, now there is a high loop and a check vale. And I won't be doing any crossings from Halifax to St. John's. Rob Abbott AZURA C&C 32 - 84 Halifax, N.S.

We were motoring back to the dock - about a half hour trip and I climbed down the companionway into about 2 inches of bay water. The bilge was full and overflowing as we motored along. Inspection revealed no leaks that i could see from the engine compartment - shaft log, water pump, muffler and exhaust and thru hulls were all fine. I jump up to the head and check all 3 thru hulls there - all dry. We finally get the auto bilge pump working and pumped all the water out - and no more leak. I believe that the float switch may have been stuck. So here's my theory - under power the 30 MK1 tends to squat and the bilge outlet is below the water on the stern. We had had rain the week before and I had neglected to turn on the manual switch to get out the last of any water in the bilge - the float switch always leaves a few cupfuls in the bilge. I am thinking that while under way with the outlet submerged, the bilge pump cycled on. Then - as usual - the remaining water in the hose flowed back into the bilge. But this time with the outlet underwater, it started water siphoning into the boat. After cleaning it all up I checked it in the morning - and it was dry as usual. The bilge hose has a high loop in it but no air break or check valve. I am thinking a check valve or an air break would keep this from happening again - any opinions would be welcome. Oh - and I think I will fix the manual bilge pump that I have been putting off for a while! thanks, Joe _______________________________________________ This list is supported by the generous donations of our members.
