im going to mount a winch on the cabin top port side. looks like my mounting bolts will penetrate right at the light that serves the galley. i dont have the light there anymore, but i do use the leads to feed a tube fixture over the shelf in the galley. i figure if i hit those wires i will also knock out the ones feeding the head and the vee berth. not worried about the mast wires, because they have already been replaced. anyone know how they feed to the spot where they drop to that fixture?

That is a tough one as the wiring has varied in the C25 but you could possible find the placement of the wiring if you can get access to the back of your galley bulkhead and check their direction. Some of the 25's have all the wiring come together close to the fuse panels. You might not have any wiring in the way but you could place and drill your holes with a Forstner bit which you can control the depth and as you go through the each layer stop and probe. Good luck as the Captain assumes all responsibilies.

Dave,

I'd say your concerns are quite valid. In my boat, the factory wiring in that area is cast into the polyester resin based filler mush which was used to fill the large gap between the deck and headliner castings during deck build up. (Given the quantity of such fillers I've found while working on my boat, I have a mental image of a concrete mixer full of resin and sawdust supplying a bucket brigade on the assembly line where the large fiberglass castings were mated.)

When I installed a cabin top winch above the galley light in my 1979 C-25, I drilled through the wiring in two places! Seeing bits of copper and wire insulation come up with the fiberglass drill chips is a sinking feeling. To repair the damage, I used a tiny carbide bur in a die grinder (Dremel) with the patience and precision of a dentist. I was able to expose a couple inches of wire back from each bolt hole which had pulled up wiring debris. I then very carefully dug a recessed bypass around the offending bolt, repaired the damaged wire with appropriately sized marine grade wire, solder, and heat shrink tubing over the solder joint. I then bedded the repair in epoxy mush. (I'd have cheerfully used a less permanent bedding compound, but this is after all directly below a halyard winch!) I then replaced the galley light with a 6" or so round stainless steel light fixture (with glass lense, 2-bulbs, and a 2-way switch) exactly centered on the winch bolt pattern. This not only hid the winch bolts, but the headliner surgery is almost invisible, certainly not obvious. Other possible cosmetic repair techniques might include gelcoat (challenging in that location), and/or mounting a light on a teak backing block large enough to hide the headliner damage.

Good luck!

Bail on the light location. You may need to make sure no shorts are caused by the holes but a dentist pick and some caulk should get that done for you. I believe you are dealing with a leg of wiring not the trunk. Install a new galley light over the ice chest, it will be easy to do with the power wall so close. I always thought a nice florescent would fit up there well.


here is a poor shot of the location of the winch I added.


Here is that location from the top.
