I am about to install a electrical system in my M15. This includes a masthead tricolor and a masthead antenna. I have two questions about the external wiring and two about internal wiring. External: 1 - with a combined coax and 3 wire cable and 2 wire cable is there a need for strain relief at the top of the mast or is the distribution over the three fixtures (masthead, steaming light and antenna) enough? If needed, how do you do it? 2a - Thru deck wiring - I bought a thru deck fitting for the coax and after the connectors are on both ends there is 15/16" left for the deck thickness. Is this sufficient for an M15. If not what do you recommend? 2b - What do you recommend or use for the mast wiring thru deck. All of the fittings in the catalogs look ok for 35 footers. I am mentally down to using a trailer wiring harness thru a compression fitting from West Marine. Any Ideas? Internal wiring: 1 - what do you use to route and attach the wiring to the ceiling and walls? 2 - the battery specs say a gel cell battery can be "operated" in any position. Does this mean you can install it laying on it's side safely? Thanks Doug Kelch M15 #310 "Seas the Day" __________________________________________________ Do you Yahoo!? Yahoo! Mail Plus - Powerful.
