Re: Expanding foam to seal mast step cable hole?
The largest is a VHF cable, and it is the "big" size (around 12-13mm). There are also 2 16ga power cables (steaming and anchor lights) and a small rectangular (telephone-style) wind instrument cable.
I've thought about putting some sort of "hat" on them that deflected the drips, but don't have a great design in mind. I think it need to be larger than a standard grommet. Ideally it would also fit around the existing connectors.
This must be a common issue on other deck stepped boats. The advice that I read in books is to put a drip loop onto the cable, but that is nearly impossible with a big heavy duty VHF cable.
