Dunno: water gets into the bilge anytime there is water in the cockpit/cuddy. This is mutually interchangeable, since even if no spray flies into the cuddy, there are drain holes in the bulkhead that allow water to flow back and forth, and when in rough seas, that WILL happen. So, any water inside the confines of the gunwales is subject to finding it's way into the bilge ...
So far in my quest for "bilge dryness" I have done the following:
- Epoxied over every single old bolt and screw hole I could find, from the lowest points of the cuddy to the highest points on the seatbacks, as well as any holes in the CB trunk. Basically anywhere that opens up/leads to the space between (great Dave Matthews tune!) the cockpit/cuddy pan and the bilge
- Removed and re-bedded with sealant every existing piece of hardware screwed down to the cockpit/cuddy pan/CB trunk, such as the mast base, CB up/downhaul controls, jib fairleads, and all the openings I've created for all the electrical stuff I've installed.
Still have leaks into the bilge. John Alesch recommended that I check the hull/deck joint seam, which I've done. No voids there. I've done the CB uphaul through-hull opening fix as best I can without being able to actually remove the CB (which I can't), and I think I have that area sealed up pretty well. But when I fill the seat cooler with water, then reach down through the port opening, I can see/feel the water dripping through. So, yes, I have a leak there, and am not sure how to go about finding/fixing it ... ?
When you put the hose in the bilge, how much do you fill it up before you see water coming out the bottom? Might not be coming out of the crack - could be that you need to replace your CB pivot bolt washers (your PB looks pretty clean and easy to access), and/or do the CB uphaul fix as well, and you may as well do it while you have the CB outta the boat.
