I Think I Want A Bigger One.

If what iv`e shown so far is not quite what is required. There are two other pages of coils 7 pin, 13 pin some with wires at one or both ends. There are also sockets to fit the plugs into or you can get rubbolite junction boxes if you want wire only connections. The coil diameters can be 2 or 4 inch and they come in 3 or 4 metre lengths. Pm me if you need help.

Just to chuck another idea into the mix. The simplest connection I’ve seen for a sliding roof solar panel had the panel connected to two cigar sockets on the roof. Front and back, and a lead off the rear coach roof just inside the wheel house. You do, of course, have to remember to disconnect before you wind the roof up or down. Simple and cheap to make.

well heres a much cheaper 3c version -

these are heavy duty coiled cables - https://www.simbal.net/product-category/spiral-cables/ they do a 4 core version, might be worth talking to them as they can supply up to 25m lengths

the orange stuff can handle up to 50A

I am quite interested in the Sterling alternator to battery chargers for this but have no direct experience of them as yet.

Just catching up here. I fitted one 5 years ago when the engine was changed, it's charging 3 110ah domestic batteries and a 95ah starting battery, never had a problem with it and only need 2 or 3 hrs running to charge them up. Let me know if you want anymore info as long as it's not too technical.

My thinking thus far is that if the curly wire id attached to the furthest starboard rear edge of the canopy, and anchored to the furthest port side of the cabin within the canopy, and if roughly speaking the canopy is 10ft wide and has a travel of again 10ft then when the canopy is down, the curly cable is stretched top about 15ft, well within the stretchy limits of curly cable. I would install a length that would hang down from the cockpit roof to the cabin roof then across the boat, perhaps giving me a total length of up to 12ft.

Lost me, MM! Not difficult, I grant you. Why are we talking about port to starboard? I can't visualize this arrangement, you'd end up with a cable diagonally across the cabin, surely? Either across the top of the rear roof with the roof slid back, or across the cockpit with it slid closed. What am I missing? Apart from a few billion brain cells?

Thanks Grendel, the orange stuff looks good for the application in mind.

Ray (Regulo) What I have in mind is that when the cockpit is in the closed (up) position, the cable goes straight across the back of the cockpit from the top (on the sliding canopy roof) Starboard side to the bottom ( on the fixed cabin roof) Port side. In this position the cable would be in its "relaxed" state. As the canopy is slid back, the cable would be stretched diagonally across the boat, between the cabin top and the sliding canopy.

If we say the sliding wheelhouse is 12ft wide and the distance travelled between open and closed is also 12ft that would require the cable to stretch from 12ft to 17 ft. Roughly speaking 4 metres to 6 metres. at that rate, there would never be much tension on the cable or the fittings.

Sorry, but I might be being thick here, but why does this cable go from side to side when, without seeing it, surely it only needs to run front to back.  Also if said cable started say a foot further forward from the rear coach roof it would only need to stretch 10ft. I am, of course, thinking of the cost. Beer money comes to mind. :default_beerchug:

1. Side to side can be better hidden

2. Side to side is less of a stretch, reducing both strain and wear & tear.

3. Side to side on the back end of the saloon means it can't get in the way.

I can find no advantage for the cable running Fore to Aft, though I am more than happy to hear of any

Have you allowed for the up and down movement in the canopy as well? You would(I think! correct me if I'm wrong!)need to have the cable running diagonally across the rear window when the canopy is up, otherwise it would get dragged down the side of the aft cabin.

If you are going to invest in one of those coily things, you need to think about how compliant the coils will be to lateral compression. How much clearance you have between the aft cabin roof and the sliding top's head-lining and whether said headlining is likely to be damaged by having the coils dragged up and down it and possibly squeezed into it.   On my 35 there is only about an inch clearance when the cabin top is right back and I don't think the thin vinyl headlining would survive long. Of course, your setup might be different but I thought I'd raise it as something (else!!!) to think about.

Poor old MM, he's reaching peak critical thinking overload! His brain will melt if we keep throwing more things to think about at him.
