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?

On my MiniCup, I used standard drain plugs like these that are available
from http://www.duckworksbbs.com/hardware...0-20/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.

Andrew:

I thought about using these but where to put them. 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.

The side bulkheads are more for structural purposes than to provide any real
amount of floatation. 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 -

That looks pretty nice. I'll think about it.

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 was actually going to do that with a water fill, the plastic type.
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.
