Drain plug

Hi 
New member, first time posting.
I have a CM21 and wonder how the drainage system/drain plug is suppose to work. The previous owner had the bottom plug capped off, and the cockpit drain plug open to just drain inside the boat. To get the water out of the boat he had a small electric pump to remove the water that accumulates inside the boat. I don't think that is the best way to remove the water since every time it rains the inside of the boat get filled up with water.
Does anyone have any pictures/suggestions on what I should do to solve my problem?
Thanks for any advice.

Hi Finnz,
Welcome aboard. There should be a plastic tubing connecting the cockpit drain to the thru hull fitting at the bottom of the boat. To replace it you need to be small and/or not hindered by tight quarters. It sounds like the tubing started leaking and the owner just pulled it off and capped the exit hole. I'm not sure about the diameter of the tubing. It looks to be about 1 inch and has a clamp on each end on mine.
You may also be able to access the tube by removing the hatch to the rear port side that covers the storage area there. Mine happens to be open under the cover. I'm not sure if they all are.
Good luck.

Thanks Russ,
So does that mean that once the cockpit drain is connected to the the hull fitting with a tube, that the water will drain out. There is no plug for the drain? Water doesn't come back thru the hull fitting?

Welcome, im restoring a Clipper and wondered the same thing no water does not come through... i had water getting in the interior from the top and simply put silicon around the edge to seal the top hope this helped.

Finnz,
The cockpit is far enough above the water line that the water should  not come back up through the tubing. Even if it did it would only be in the cockpit and then drain back out. My biggest problem with the drain is it plugging with debris. I get leaves and such in the boat and then with rain it plugs the drain. Much better than a boat full of water though.

I keep a straightened out coat hanger on board to clear debris jams in the drain. Works like a charm.

Everyone is correct, the waterline is far below the cockpit and the water will not come back into the boat. I have clear tubes and I can see the water level is about mid way up the tube. I get a little splash every once in a while when I am in choppy conditions but never on flat water.

Thanks for the answers.
Does anyone know the dimension of the tube that connects the cockpit drain to the thru hull fitting at the bottom of the boat? Is it attached with hose clamps?

Hello Finnz
The tube on my 21 footer is approximately 4.5 inches long and 1 inch ID. It is just clear vinyl that can be purchased most anywhere and is held on with hose clamps.
Hope that helps.
