It has rained the past week here in OH and I have my Penobscot outside trying to work on it since the shop has no room. I have bailed it out the past 3 days and getting tired. What can I put through the hull next to the centerboard to drain at the low point while on the trailer? I was thinking maybe drain plugs mounted backwards through the hull? Pics in a few

I know I can place a cover over it, but it would be nice to drain this after a sail and placing back on the trailer.

Bronze garboard drain plug. Available numerous places, the plug has 1/2" NPT threads and the flange is about 2" in diameter. Mine is in 9mm planking and I cut the #8 screws to not penetrate the planking and bedded it with silicone.

did you mount them with the plugs facing in the bilge?

I mounted it flat to the inside of the planking, near the forward bulkhead in the Oughtred Fulmar I'm building. The thought is that I can set the trailer tongue on the ground and the plug will be at the lowest part of the bilge. It's just forward of the centerboard case where I'll be leaving an opening in the floorboards above it big enough to easily remove the plug and also sponge out what won't drain.

One thing I did before installing the flange was to belt sand the bottom where it sticks through the hull to make it flush with the planking. With the tapered threads of the plug it doesn't extend past the outside of the planking.

I put a plug at each end so my boat will drain whichever way it's facing on a slope.

Letting it dry out and then some epoxy. I am going to skinny the drain up on the lathe at the shop tomorrow so it isnt so proud.

If you have a drill press, a hole through the plug into which a bit of welding rod fits is not a bad thing.

I just put a brass tube into the bottom and flared both ends. I use a rubber plug with the flip lock handle. It seems a lot easier than trying to keep sand out of the threads.

Silly me, I drilled holes and push in corks. I had a 1927 Triangle sloop with that arrangement. Liked it.

I thought about rubber plugs, even smaller livewell plugs. I am trailering this and didnt want them hanging out the bottom to get snagged. Thin ply lapstrake. All great ideas and thanks

Took me a minute to figure this out, Im slow. Yes for sure, will modify with a tee for easy remove.

I've had the flip lock plugs; disconcerting after a few years when the pin holding the flip lock corrodes out and the lever fails. I think these are OK if boat is on a trailer most of the time. If it is in the bilge of a boat that lives overboard alot, I would keep an eye on it. These are mostly designed for trailer outboards.

And Thad didn't mention the dory's traditional plug; a wooden one with a loop of line going though the bottom of the plug. Think upside down, something to hang onto and maybe right the dory.

What Mike said, and if you have a rolling swing-away jack you can lower it for drainage rather than having to fold it all the way down. I vastly prefer these in the bow!

And I also am a fan of the SB garboard drain plug as pictured above. I cut a slot in the square top to allow use of a knife back or coin to loosen & tighten it, but so far it stays free if just hand-tightened.

thats where my hole ended up, in the bow. I was going to put 2 in the center on both sides of the centerboard, but decided against it after lowering the trailer to work on it. Big puddle of water in one good spot so I drilled a hole.

I let one of those garboard drain plugs into the plank keel of my peapod. Works a treat. Hand tight is plenty, and keeping it clean of sand or grit has not yet been a problem, even with plenty of beach use.

Replacement Nylon drain plugs are also available which have a flat tab on top (easier to grasp and turn) and also have a loop for a keeper/safety line. Search on eBay.
