A Catalina 310 I’m looking at has water in the what I call the main bilge, just above the keel. The boat has had a previous Catalina Smile/Keel damage due to a hurricane when the boat was pushed into/onto a shallow flat. The boat was on its keel and side so caused a Catalina Smile/Keel damage. It was repaired and supposedly is good to go. That was about 4 years ago. I've read and been told that the Catalina is a "web bilge" boat... The water level is 1-2 inches, just in the very bottom, and is stagnant like it’s been there awhile. Water color is a very dark brown. I failed to get pictures so I can’t share. The keel bolts were not corroded and just looked a dark gray. There were three bilge pumps in the bilge area. Stains on the side of the bilge seemed to indicated the water level was consistent and had been there awhile The overall condition of the boat is immaculate so I was thinking it’s most likely water that has just draining into the bilge over time and just sat there as it’s below the level to trigger the bilge pumps. Other areas under the floor looked really clean. I’d eat off the floor under the engine. Thoughts? Any way to tell if this is a problem or if it’s just a small pool from whatever?
