Affixing electric cables to contours of hull

Post by Tezza » Sep 29th, '18, 08:25

Mango being 33 years old is suffering from the dreaded “ cables hanging down everywhere”.
I have tried a couple of different cable holders packs with sticky back from Bunnings with little success. This is in those areas where there is no internal liner or carpet liner such as from one side to the other under the cockpit or along the cockpit wall in hull from stern to cabin. How do you do it? Thanks.

But how do you fasten the cable trunking to the underside of the deck?

Silicone. I prefer cloth tape directly over the cords, easy to remove and you can paint it.

Well my boat is about 35 years old and I thought that cable trunking was the answer, but now I've just got the dreaded cable trunking hanging down". The real problem is finding an acceptable way to attach cables or trunking to the inside of the hull so it doesn't come off.

I shall test duct tape... (the stuff with the cloth, not the wide insulation tape) thanks

Zebedee, what did not work?

We can learn from failures.

I used the white square conduit, comes in different sizes and secure it with sikaflex.

The sticky backs will work but you will need to scrape all the sticky back off clean and rough up both surfaces and use silicone, sika, epoxy, tarzana grip, locktite 401 etc.
Another thing that has worked for me is just cleaning the fibreglass surface, putting a strip of good quality/adhesion (3M) tape down, the stuff I used was a couple of inches wide, and then putting the sticky backs onto the tape. This has held for a couple of years so far.

+1 , stuck it with sikaflex and left it alone until it cured before running the cable.
On the curved section had to hold it up with a piece of wood cut to length and wedged under it until it cured.
to help it stick better wipe it with acetone before gluing it and run a bit of sandpaper over the back.

inside the tubes where I didn't have much elbow room I used double side tape half the width of conduit then ran a sikaflex fillet along it.

I like the idea of the square conduit .How does it go with going around corners .

Plastic square conduit will follow the internal curves of a yacht hull quite easily. Fitting it around square internal and external corners just requires basic wood working skills. It does look very neat when finished far better than round conduit. I fit it using industrial double sided tape to locate it while Sikaflex adhesive sets. Using this technique on aluminium hulls I have never had square conduit come adrift. Just make sure both surfaces are clean and lightly sanded for the adhesive to bond to.

I have square conduit but it is slotted and allows cables to be dropped at any point, I am trying to remember the name of it, Sikaflex marine holds it well.
It is useful because of the slots which also make it a bit more flexible, almost like combs on both sides for the entire length, snaps together like the Bunnings one.
I also made the mistake of buying some that was too big if anyone is interested in it.

Is there a link or manufacturer for this tape?

Finger Duct. Electrical wholesalers (ideal, haymans) or Jaycar even would sell it. Heaps of different sizes.

Oh dear Tezza. Give your wife your wallet, go to the jaycar website and download the catalogue.

Jaycar is similar to dick Smith before dick sold it. Full of fun stuff for those that like to tinker with electric/electronic things.
