Boat Forum / Building / February 2007Very small deck plates
I am looking for very small (2-3") diameter plastic deck plates to put on the sides of my miniCup sailboats to allow the side comparetments to be drained if they somehow fill with water. I want something like a deck plate that will be very low rise above the deck. (I used 4" deck plates on forward and aft compartments). I cannot find them on the net or in catalogues. any ideas? >I am looking for very small (2-3") diameter plastic deck plates to put > on the sides of my miniCup sailboats to allow the side comparetments > to be drained if they somehow fill with water.

On my MiniCup, I used standard drain plugs like these that are available from http://www.duckworksbbs.com/hardware/plumbing/sd520010-20/index.htm or West Marine etc. In the years that I had the boat, which included the cockpit being filled with water several times, I never had anything drain out of the chambers.

If I put em on deck, I'd tend to sit on em, uncomfortable. If I put em inside the cockpit, they'd have to go through the stringers at the base of the cockpit. I did get water in the side compartments just due to cracking of weak joints over time. I am fairly certain I have solved that problem after glassing the whole boat but I'd really like to be sure. On this boat, I had rotting of the forward compartments due to water getting in from the mast step. The back compartment was dry. Now both front and back compartments have 4" deck plates and I have rebuilt the mast step to be very solid.

If I remember correctly, I installed the drain plugs on the tops of the bulkhead reasoning that turning the boat on it's side would allow them to empty them. I was actually more concerned about allowing for air expansion in the sealed chamber than about water. Since these chambers don't provide much floatation and there is lots already in the boat, you may want to consider cutting a large oval out and re-inforcing it from behind with a nother piece of ply. Keep the original piece and use it to cover up the hole keeping it in place with a pair of butterfly nuts (I just cut the butterfly shape out of 1/4" plywood and use a screw to attach it). I found my jigsaw worked well if I tilted it up before starting, the slowly lowered it down onto the piece. This prevented me from having to drill a starting hole. This provides you with a storage space and an easy access for repairs. It's not water-tight but you've got lots of floatation already. The doubled thickness of plywood should replace the structure you are taking away with the hole. Here's a similar setup that I used on the Weekender that I'm building - http://www.floatingbear.ca/sailingfiles/Weekender/Seats6.jpg AndrewB > >> "Frogwatch" <dboh...@mindspring.com> wrote in message > [quoted text clipped - 48 lines] > > AndrewB Andrew: That looks pretty nice. I'll think about it. David These aren't cheap (for this purpose), but if you really need something that size, and such that you could sit on it w/o something poking you, get a water fill (plastic if you can). You would need to wack off the hose barb, but it would still protrude into the compartment and not allow full draining. If it's threaded you want, it will probably be "proud" either inside or outside We once had a French catamaran that had two bungs (a 2 inch flanged hole with a screw in plug), one over the other in the center cabin module that i believe was used for lifting this module in the factory. So it really wasn't a "drain plug" (although I used it as one) and may have been an industrial item. The flange, and no more of the plug, was raised about 3/16". I have never seen one any where else. >I am looking for very small (2-3") diameter plastic deck plates to put > on the sides of my miniCup sailboats to allow the side comparetments > to be drained if they somehow fill with water.

Then I took a good look at them and realized that even if I cut off the hose barb they still will not allow drainage cuz the screw-in cap goes down into the female part a ways. |
