Wires through deck

[brak]

What would be the best way to run multiple mast wires through the deck? There might be at least 3 of them, about awg 10-12 each (dual cables). I'd rather not install 3 separate fittings for each. Would it be possible to run all 3 of them through the same larger fitting and somehow tighten it properly?

A couple of questions:

1) Do the cables need to be run continuously, or can you put a splice in the line?

2) Are the cables mainly power cables?

While you can run all three sets of cables through a single cable clam, there's a really good chance it will leak, because it will be hard for the rubber fitting to seal around the wires properly, since there are three cables.

You can also use something like the SureSeal connectors to pass two power cables sets through the cabin top using a single cable clam.

Try a good length of heat shrink tubing around all the wires with a sealer beneath that, then shrink while sealer is still wet. Work from the center out. That will provide an better surface for any kind of grommet etc. to seal against as well as stop water from funneling down along the wires themselves.

Having a disconnect on deck is a good thing. I looked at their catalog though and I am not sure they have a right connector. In a simplest case we have an anchor light, a masthead light and a deck light - 3 double wires, awg 12ish. For a single connector, I'd have to have a 6-pin connector rated awg 10-12. I'd love that but I don't see it there.

There are things like this available as far as mating on the exterior...but that still leaves you having to stay dry thru the deck. Lots depends on what you have as far as cabin top. If you can access any hole you make I am sure you can find a suitable weather proof multi pin male and female with a permanent dry mount for deck end.

Or maybe better yet? as I just reread where you may need more connections.
Still leaves the thru deck thingy tho.

Bulgin Components: Manufacturers of Mains & Waterproof Connectors, EMI Filters and Security Switches

Bulgin makes waterproof "bulkhead" connectors in commercial grades, sold in the US by electronics shops like Newark Electronics and Mouser and possibly DigiKey.

Multiple pins, solder or crimp, replaceable, screw-on caps for both sides of the disconnects. I'd suggest ordering a spare(s) because if you ever need to replace it, these things are never going to be at your local chandlery--they're professional/commercial equipment. And they beat all hell out of the trailer-wire harnesses a lot of chandleries sell.

You might one to get one with more pins than you need, in case you add anything in the future, i.e. deck lights.

Wondering why you don't run them inside the mast ???
