I am contemplating moving my bilge to the area infront of the door. Luna Sea doesn't have enough weight in the stern to get the water back there.....

Does anyone know how much space is under the deck infront of the door? thinking about 'glassing in a sump there with a cover for the pump....

Suggestions? Ideas?

Thanks

There is no space under the deck. You are standing on the outer hull. The only suggestion I can think of would be to keep your fuel tanks full, which would add weight to the stern.

The newer boats have the bilge pump in a "step" inside of the cabin. There is a hole drilled thru the bulkhead between the cockpit and bilge pump. (This should be epoxy lined and right at the bottom of the inside of the hull)--yes, you are standing on the bottom of the hull, there is no floor with a void between.

I would put in a second bilge pump inside the cabin, or outside of the cabin--and leave the original. I will be adding a second pump in the aft area--in the 2006 boat.

Yes and no. The deck is cored and there's considerable thickness in the hull in this area. Many of the newer CD 22's have bilge depressions in this area that are actually glassed in under the door with the bilge pump on the inside of the cabin in a box that's just forward of the door. This re-design was due to exactly the problem he is describing.
 
Here's one way...

I'm glad this subject came up.
I am contemplating glassing over the opening on the starboard side of the cockpit that lets water into the holding area under the inside cabinet.

Why? Well, I just hate the water that collects under the cabinet, I leave a large sponge in there and I am forever sponging and bucketing water out of there, which involves opening the cabinet door, getting down there and carefully sponging and putting in the bucket and then dumping overboard. The mid hull bilge pump never gets any until the level of the water gets high enough to flow through hose to that bilge area under the step inside the door.

The water collects in there as I pull crab and shrimp traps, a lot of water in those lines. Also when I wash the deck after bringing fish on board. Of course, when the boat is parked on the trailer, even tilted up on the trailer when it rains.

If I forget to sponge and bucket, water splashes around and gets gear wet under the cabinet when I am running on the water and when I trailer to and from the boat launch.

Any thoughts on this? How best to glass in and gel coat the outside opening at the bottom of the starboard outside cabin wall?
 
I put in a second pump a few years ago under the cabin door. Pics are in my 'projects' album. Here's a peek

It was pretty simple. Salmon Fisher, our boat is a 2001 and had the same dumb location your boat does. I just glassed the opening closed when I did this project.

Thanks everyone. Foggy Dew- I admired your project before and may end up going that route. The inverted pump looked like a possible solution but the marine shops here looked at me like I was crazy when I showed them picture :)

Does anyone have a picture of the new C-Dory sump/depression in front of the door? Anyone hazard a guess how much space in beneath the deck in front of the door? I getting crazy ideas of drilling a 5" hole there and dropping in a PVC insert with a bilge pump in it......
