Ken You are correct. http://users.eastlink.ca/~mhoyt/Projects/Phase2/garboard_drain.htm At our club (Barrachois Harbour Yacht Club) a number of owners had installed these oarticularly after one boat had installed a new cabin sole in the Fall that was ruined by water buildup in the cabin over the follwoing winter/spring. We have a freeze/thaw cycle here that tends to have snow in the cockpit followed by rain then freeze which closes off cockpit drains and then drains into cabin sometimes. Typically these are installed from the outside using something liek a 1 inch flush drain (Perko I believe). Many of us would then fair around the flange causing a slight bulge. We did it this way on our Niagara 26 "Full Tilt 2" and our friends on their C&C 25 "Dry Red". Once we bought the J/27 I could not do this since this sort of protrusion is sacrilidge on a racing boat so I decided I would try it from the inside using a half inch drain. This worked very well and I use either thickened epoxy or a polyester based filler to fair the hole each spring so that it is undetectable and then in the Fall I pop out the fairing and remove the plug. Seems to work well. Our friends that had teh 25 liked this idea and did the same on their C&C99 Mike ________________________________

I know I've run across it before. Ken H. On 4 September 2013 14:46, Hoyt, Mike <mike.h...@impgroup.com> wrote: Good idea Bill except that the boat will sink .... Seriously though - I have put garbord drain in my last two boats. Very difficult to put at absolute lowest part of bilge but it does ensure there is never a serious water buildup over the off season. Water collecting in a boat on the hard does nasty things Actually I install mine from the inside and completely fair over the outside. There is no bulge or any trace of the garbord drain and it has zero effect on flow over the keel this way. Previous boat I did from the outside and there was a slight bulge.

The past two winters with the boat out of the water there has been no evidence of a smile but I have been concerned with the bilge and it always having water in it. Keel stepped, when it rains, water in the bilge. Aside from that any condensation in the boat, the stuffing box (which needs repacking), etc, and I have water in the bilge, all the time.

I have heard this comment several times before also. I am not aware of a large nimber of sailboats that do not have some water in th bilge most if not all the time. Since this is where the kell bolts are torgued with the nuts it seem that this would count as wet and oxygen deprived. Am I missing something or are we all in imminent danger?

Remember that the keel bolts are stainless which will degrade when wet in an oxygen deprived environment which is what happens when the keel / sump seal is compromised. A good starting place would be get the opinion of your local fiberglass repair shop. I believe this subject is also well covered in the archives of this list as well as the DIY section of the photoalbum. To be absolutely sure, the preferred process at haul out would be to 1) lower the keel, 2) clean, fair and prep the mating surfaces, 3) reattach the keel with a preferred adhesive / sealant, 4) properly torque the keel bolts, 5) grind and fair both sides of the joint by at least a foot, 6) apply fiberglass as a fairing, 7) fair the fiberglass, 8) apply several coats of barrier coat then bottom paint. If this is too much, then you can try digging out all bondo and as best you can expose the joint as deeply as possible. Clean it to provide a good sealing surface. Stuff in your sealant, then proceed at step 4. Fiberglass tape provides negligible structural integrity. The keel bolts and adhesive at the sump / keel joint do that. The tape is to fair the joint. If there is insufficient structural integrity, the keel will flex and break the tape bond.

This season I've noticed that I'm getting some sea water into the bilge ( along with rainwater that comes down the mast ). On haulout this year I'm planning on making a more permanent fix. Has anybody used G-Flex epoxy for this project? I plan on using thickened epoxy to fill the gap and then use wetted out fibreglass tape to strengthen the joint. Comments, ideas and suggestions would be appreciated.
