This is the third installment of a (hopefully) short series of
re-wiring questions g.

I'm running a bundle of wires from the transom to the cockpit, along
the side of the hull up under the gunwhales. It's an old boat, and
there is no wireway, PVC, or other convenient means to keep the
bundle from moving around.

Since the sides of the hull are single-layer fiberglass, I was
thinking of using those stick-on cable tie mounts to fix the cabling
up under the gunwhale, but I don't think they are legal to use. I
think the current standards call for "real" stainless clamps with
the rubber chafe covering, like the ones Ancor makes. But,
obviously, I don't want to drill holes in the sides of the boat to
mount the stainless clamps with nut and bolt.

Any ideas that won't get me into dutch if the CG takes a look? How
do other manufacturers' do it?

If you have room, run a plastic tube the full length of the boat,
and leave enough room in the tube diameter to pull further wires
through at some later date. Fasten the tube in place with clips or
epoxy to the inside of the hull. We used toilet outlet tubing, but
chandlers carry all sorts of tubing. Once it it in place, it's easy
to feed extra wires through when needed.

There is a flexible, split plastic tube made precisely for this
purpose, called "wire loom". You can bundle the cables in there and
then fasten the tube to the sides using whatever is handy. It is
available at both auto parts stores or marine stores. Guess which
place is cheaper!

They also sell it (the flexible split plastic wire tubes) at home
improvement stores like lowes or home depot, it's way cheaper than auto and
marine stores. It's basically for running conduits in moving vehicles (RV's,
cars, boats, planes), while you can stick it/glue it to the sides, make sure
you use a flexible glue (not epoxy) that can take the constant vibration
while the vehicle is under way. Butyl rubber (that black stuff used around
windows) is good for that, stays flexible and is waterproof.
