We have a 1997 Beneteau Oceanus 321 (new to us) Does anyone know the size or where to acquire the "O" rings that are located under opening port latches ,have made some inquires to different suppliers with little or no response.
Joker,Just in case you're having leaks.
Most of the leaks of this era style boat is the sealant at the joint. Lewmar had a maintenance note on their website.
I thought that I had a problem with the O Rings and the gasket because that's where the water looked like it was coming through.
When I re-sealed the joint all leaks stopped.
The O rings you can get at your local hardware store.
