Cable Routing

Question:

What route do your cables take from the console to the transom / engine?

I know the ribtecs have an underfloor duct but what about other boats?

I have a feeling there is no underfloor duct on my Ocean Pro (collect it Saturday).

What are the pros and cons of underfloor / deck routed cabling?

Regards
Nick

Well, we're completely spoilt with our Scorpion...

We have two built-in conduits running from under the console (where there are are long bellows attached to the entrance holes) which run to the aft well. In the well is a cleat with two cords attached - one for each conduit so that new cables can be run under. The other end of each cord is attached under the console.

Pros and cons?

Well here's a starter for ten...

Under-deck:
+no trip hazard
+no physical wear-and-tear
-can's see any problems
-probably more difficult to diagnose problems

Nick - underfloor every time, mine has a truncking running up the deck from engine to consoul, gets in the way and is something to trip over, the underfloor makes not much difference when threading new bits of kit as instead of threading them through the deck trunk they just go under the floor in the trunking, in addtition it also looks a lot neater not having cables down the deck plus the exit point on the deck with a gland on looks neater than than a trunk run up the deck with a bunch of cables spewing out of.
All IMO of course

Hi Nick

My Ribcraft is also under deck, with a pull cord fitted & bellows each end. Keeps deck clear , tidy etc and as the console & engine bay are sealed stops any possible flooding to either which could happen with a overdeck routing.

Underdeck is the way to go,

When I looked at Humber they run over deck on the basis its easier to fix. However I think while it will be easier to fix its also much easier to damage things and not very tidy.

Only thing I would change is have two ducts, or a bigger one.
When they was fitting it it looked big enough to drive a bus through, but now adding more cables is already getting very tight.

Regards Gary

Cable Routing

Nick

Humber do not have under floor ducts.

They do provide a console to tubes cable tunnel

Humber list it as "Deck cable tracking GRP" at £20 in their pricelist

I suspect it is screwed to the deck between console and tube so it is a tripping point, but fairly short, with the cables running along the deck edge against the tube.

I am on the lookout for some heavy duty spiral wrap to protect my cables.
Does anyone know of a supplier?

John

Hi

My Ocean 6.25 has underfloor truncking, just remember to have a length of rope more than twice the trunking length permanantly threaded through to pull through new cables.

If you can get two or three trunks the better.
Fuel lines in the same trunks as electrics? good idea
From a comms view point data cables with power cables and RF cable not that great an idea. Data cables need sheilding from RF and Power, though as power is DC shouldn't be that bad.

On my boat the cables are run along the side of the tubes in what looks like the trunking from Do It All / Homebase.
This seems to do the job ok from my point of view.

Thanks for your comments.

I was a little dissapointed Humber dont fit under deck ducts, it'll never look as tidy on deck, even if it is tucked away to the side of the deck under the tubes!
I was under the impression that most respected boat builders would do this - aparently not!
Hey Ho.

Headhunter, this link may be of help - depends on how big the loom is - Maplin - only goes to 24mm though - Have a look...

I bought my wrap from http://www.bosunsmate.co.uk/

The short trunking provided by Humber isn't ideal but haven't had any problems tripping or squashing anything.
I am still undecided on above or below deck cabling. Below deck is neater and easier to modify but above deck doesn't spend all its time underwater. Have had problems in the past with cables soaked and nicks in them wicking seawater up and corroding them.
I don't know which system I would pick given the choice.

For all those with under deck trunking...

2 questions:

1 - How do the cables protrude from the trunking at the stern by the engine?

2 - How do you drain any water from it?

We could have had under deck, but were dissuaded for 2 reasons:

1 - We were told the cables would sprout upwards from an under deck system due to having to bend upwards to come out agan. As we have a bottle rack at the back of the boat, any dive cylinders dropped on the cables would bend them badly and cause damage. (We saw this on the tornado demo boat)

2 - under deck cabling was hard to drain and could end up getting water into the hull - thinking about this one its probably because they hadnt got a very good system of doing it.

In the end we had an solid aluminium cable run on top of the deck going backwards from the console, which works pretty well to protect the cables and keep them flat and unkinked. I havent fallen over it so far!

Cable Questions?

Thorper,

I'll post some pics when I get home of my setup, & the answers will be fairly obvious.

You could always buy a Falcon.....Centre channel runs full length with access into both the console and the rear Battery locker.

Ours simply exit at two large "slots" in the top of the bilge pump well.

The deck slopes down to the stern, so both the conduit and the deck surfaces drain into the well.

Pictures from the front of the boat.

The cable go's from the console into the bow anchor locker.
Yes, that is vacumn hose protecting it.

Because of the way Humber attach the tubes to the hull, you'll find that the cables will lie very nicely under the bottom of the Humber tubes. Make sure your steering cable is also routed that way. The bit of channel Humber supply to link across the deck doesn't look too cool but is does work fine. Do not use spiral wrap to bind the cables along their length. Use re-usable cable ties. You can use spiral wrap at the stern to protect fuel lines etc. When/if trimming the ends from the ties, ensure they are not placed to fret the tubes by their sharp ends.
A good supplier for reusable and durable ties is a plant nursery which sells trees. They are used to fasten the protective plastic sheath which is used to protect the base of a young tree for a few years of its early life. They are very strong, last for years and the end can be turned back into the clip rather than cut off.
