Our
bilge has several "compartments." I figured this out after installing an
electric bilge pump. I would check the
engine compartment - almost the lowest spot in the boat and the
bilge pump was keeping things nice and dry.
We would then get back from a sail and there would be water on the
cabin sole. I tasted it - fresh. Perplexed...
That's when I figured out that our
cockpit lockers leaked rain water past the
seals (on the to do list) and that when we heeled the lockers emptied into the
bilge aft of the engine. When that was full and we heeled it drained into the forward compartment which is quite small.
Then when we heeled it spilled over the engine cover sill into the
cabin.
The other "leak" we found was that if we filled the water to the brim and heeled the boat the water leaked out the press on cap which is a replacement jury rigged some time ago.
Keep investigating - you'll find it.
