The propane lockers do indeed have an overboard drain that is very close to the water line and as a consequence water will wash back into the locker on occasion. It harmlessly drains back out. The downfall of the setup was, or at least on my boat, that the propane line was led out of the locker to the interior of the boat at the bottom of the locker through another hole. Kinesis still has an overboard drain , but now the propane line is led through a new fitting at the top of the locker. I didn't see having a hole, even though it is sealed, to the interior of my boat at draining level a safe design.
