Always been a little irritated at the standing water in my lazarette's center bilge.
IMG_0420.jpg
1-1/2 to 2" and not enough to trigger bilge pump. Two sources. One is rudder post weep and anything in a forward bilge (AC condensate for example) that tends to move aft when the boat gets on plane. The limber holes in the lazarette bilge are too high to allow water to flow back from whence it came.
Another source was the bilge pump thru hull. It has a loop about a foot above the outlet. What it needed was a check valve to stop water from overcoming the loop and entering the boat from backing down, etc.
My solution was to turn a 15 Sq. Ft. sump into a 4 Sq. Ft. sump by putting in a 3-1/2" high transverse partition. 2" water depth is enough to trigger the pump. Any catastrophic flooding event will have to jump the wall. A) That's not enough to sink me, and B) I'm not depending on that bilge pump to save me, in any case.

Re: Wet Lazarette Solution
did it completely eliminate the water? I put a Ultra Mini float switch in mine. It only takes 1/2" to trigger it but I still have some water in mine.

Re: Wet Lazarette Solution
I hope so, that's the plan. There's just no good place put the pump. Plus the compartment is just way too big to put up with water sloshing around. I have to concentrate the water or nothing ever really dries.
But to answer your question. I'm sure the sump won't completely dry. But I have eliminated one of the two sources of water, and now it's manageable.Last edited by racclarkson@gmail.com; 05-24-2019 at 10:15 PM.

Re: Wet Lazarette Solution
I like the idea, it should definitely help with that problem. We have had dealings with the same thing. It seems to me that our convertibles sit just a tad low in the bow or maybe level. My thought is that they should sit now up so things can drain like rainwater ect. That little bit of water in all my bolder stops irritates me. Just never seems clean.

Re: Wet Lazarette Solution
All my compartments tend to retain a bit of water. I have resorted to using the green Harbor Freight $35 12 volt pump to empty them out. They usually stay pretty dry until I run the boat. I don't have the dripless seals so I think that's the main culprit.

Re: Wet Lazarette Solution
Why not install a diaphragm pump and suck out the last drop?

Re: Wet Lazarette Solution
Actually, were it not for rudder weep and ac condensate I’d breakout my feather duster on those bilges.
