When running wiring and cables from source to destination there will almost always be bulkheads, superstructure and decks in the way. How you get your cables through these obstructions is quite important if you want to avoid abrasion and keep a watertight joint.
To take cables through a deck or superstructure you may want to look at the stainless steel Cableport, a wonderful Swedish design that’s standard equipment on many top quality boats. It’s a polished stainless steel entry port that takes electrical and communication cables through the deck via a 49mm shrouded opening. It can take 6 cables up to Ø12mm, or more of smaller diameter.
The Cableport has the benefit of excellent waterproof integrity, a low profile to avoid snagging lines, and ‘step-on-ability’.
Deck plugs are notoriously corrosion prone and need meticulous maintenance but, if you’re up for the maintenance, they can be convenient. There’s a wide range of deck glands available – single cable or multi cable, plastic or metal; you’ll probably want the type through which you can pass a 19mm diameter PL259 connector, especially if you drop the mast each season and don’t want to remake the connection every time.
For many internal hurdles a simple hole with adequate abrasion protection will do the job but in some special cases, such as an antenna cable run from under the mast to the radio, you might want to combine a connection with the bulkhead passage. For this a good choice is the PL363 connector with two PL259 plugs. The one in the picture is a 1.75” connector fitted with two large stainless nuts.
