Dumb question of the day

In cockpit, looking forward, centered just above the floor and directly under the door.

On my 2004 C-22 Cruiser that would be where the water from the cockpit drains into the spot containing the bilge pump.

Makes sense if the cockpit floor is sloped forward. Thanks

Since I had an '01 22, my recollection is that is a drain from the cabin. I installed a drain in the bottom of the fresh water tank, after having to clean out the growing green things once. I found that tank tough to clean out and kind of a pain in the butt to remove and install. I had a plastic line that I connected to the the tank drain. It would fit through the orifice and out the cockpit drain. Result: end of things growing in the water tank. I put a 2nd bilge pump under the splash deck between the fuel tanks, and rarely had anything to pump out with the primary bilge pump.

that plug can be removed so you can hose out the cabin..or .. remove the screws holding the clear tube that displays the water level and route it through that hole to drain the fresh water tank

Like Jack & Ken, I believe it's intended to be used on our 2000 22 CD for draining water from the cabin area to the cockpit & then to the sump or out the cockpit drain. I have only used it to drain the water tank for winter or cleaning by running the hose that is normally used as a sight to quickly view the tank level, out through the plug shown in the photo.

Yup I have one of those too, and use it a lot!!

With the 2001 you have I'd guess your set up is just like my 2002.

So that plug is just closing off a hole that would allow you to hose out the cabin or etc. I never open mine but it's there if one wanted to. By the way, I removed mine to see if there was any core at the hole or the screw holes and there was not.

I bet you have the bilge sump under the galley up against the cabin/cockpit bulkhead (i.e. to starboard). In the sump area C-Dory removed the core, so the sump could be as deep as possible. Then there is a "slit" that leads from the cockpit into this sump, and a bilge pump in the sump.

Earlier boats didn't have this, and just had a pump (or nothing) out in the cockpit where our slit is. Later boats moved the sump to just inside the cabin door, and then later still they made a permanent flat cockpit sole and sloped it aft so the water drains aft.

None of this arrangements is perfect. It's just a not-perfectly-solvable consequence of a Dory shaped hull that is deepest ahead of the cabin bulkhead, but not deep enough to have a real self-draining cockpit. All of the various ways work to some extent, but none are perfect.

Many people don't really get much water in the cockpit due to either having a camper back or a slant back when not aboard. Some don't have either of course.

There is also a mini-sump on our boats (at least I'd imagine yours has it being so close in year to mine) that is aft, on centerline, just at the transom. This sump is not very deep, IS cored (just with thinner core) and originally had no pump. Many owners (or maybe dealers) added a pump there also. Often these drain along the topsides just ahead of the transom with a though hull fairly high up on the topsides. My boat had one of these. Something to check if your boat has one: Mine was screwed right into the core in that mini sump. I pulled the screws and the core was not wet so I overdrilled and filled them. But then I ended up deciding to remove the core there anyway and make a deeper sump like the one under the galley, and combined it with adding a "real" drain plug in the transom vs. the brass tube and expanding stopper style it had originally. That's just cause I wanted to, but still a good idea to check how the bilge pump is held in place if you have one in that mini sump at the transom.

So, in summary, if your 2001 is like my early 2002:

1) Plug you show is simply a plug that, if removed, allows cabin to drain to cockpit (or vice versa!).

2) Sump under galley at cockpit bulkhead is not cored and was built in as a bilge sump; slit under bulkhead allows water to get into this sump from cockpit to then be pumped out with stock bilge pump.

3) Mini sump on centerline at transom didn't originally have a pump and is fairly shallow and cored with thinner core. But many owners (and/or maybe selling dealers) added a second pump there.

A few photos:

1) The plug under the cabin door just like you have, and then to the right (stbd) you can make out the slit that allows water to travel from the cockpit into the bilge pump sump under the galley.

On our era boats there is nothing on the inside where the plug is except the back of the plug, and the hose that carries water from the water tank under the port/after seat over to the pump below the galley sink. (If yours is same as mine.) The next era had the sump and pump under a "step box" that was on centerline just inside the cabin from where this plug/hole are on our boats.



2) The stock "deep" bilge sump under the galley as my boat came (annotation is from earlier, I now know there is no core in the area below that bulge in the bulkhead or in the bottom of the sump).


3) The mini sump that is on centerline at the transom. This is cored but just with thinner core than the rest of the cored hull. (Fuel tanks are removed in this photo.)


Here you can see where holes were drilled into balsa core (no protection) to add a bilge pump. I could tell by various bits of evidence it was not put in by C-Dory but maybe by dealer or later by previous owner. It's the two diagonal holes (ignore the transom drain that's removed). This is after I enlarged them to prep for overfilling with epoxy (but I later decided to do things another way). So they weren't quite this big at first, but just large enough to screw the pump basket down. There are better ways to hold the pump basket down though, to my mind.
