    Finished upgraded solar system

    Regarding the subject of independent controllers for each panel vs. one controller servicing multiple panels, Genasun has an interesting article about this specifically referencing solar on a boat: With a small system and inexpensive controllers, I figure every 10th of an amp I can wring out of my panels is worthwhile. I do notice the output of my two controllers varying wildly from moment to moment as the boat moves around, so there appears to be some truth to this.

    I did it primarily for redundancy and flexibility. With a 3-way switch downstream of both controllers, I can send the output of either controller to either house or start batteries. I've also read that dedicating a controller for each panel does extract max efficiency from the panels if there is partial shading on one. I understand IStream's point about wiring multiple panels in parallel to a common controller. I don't have enough experience to make a definitive statement, but I figure having a controller for each certainly doesn't hurt.

    I'm a bit envious of that frac rig. The masthead genoa on my C&C can be a handful.

    Actually, ancient sails. It's amazing that main still sets as well as it does. Yay for full battens. Hoping to get a new one over the winter. Gender sail gap...lol! Not worried, wife is happy with her 26'. She loves the 34+ too but has no interest in trying to singlehand it.l

    wire for solar installation

    Haha yeah don't look too close!

    wire for solar installation

    I used tinned duplex 12g marine wire for the short runs that are above deck. They are shaded by the panels and are each only about 2' long and easy to replace, so I'm not too concerned about UV.

    A quick little vid of our C&C 34+ sailing, shot by my wife from her boat. https://youtu.be/9CxFEx4RaEQ

    Old Keel Bolt Questions

    Have 2 C&Cs, a 1976 26' and a 1990 34+. Bolts on both have no evident problems. I took the nuts off on the 34+ this winter and retorqued, bolts looked good under the nuts, no galling. Never going to sell this boat so eventually I'll drop the keel but not worried about it now. The 26 is my wife's. 41 years old and going strong with no evidence of keel issues. Will probably drop the keel on that one at some point too but again, not worried about it now. I've also never heard of a C&C losing its keel.

    Valis - i agree on the accuracy. I'm seeing 0.2-0.3 variance also. As you said, good enough for my purpose.

    Little multimeter They are far from weatherproof so I'd only mount them where they can't get wet. Not sure how long they'll last but for the price I don't really care. Have one that's still working after 2+ years. Edit: Yacht? Wassat? I have a money-gobbling hole in the water.

    Valis - already addressed that. The terminal posts are capped with nylon washers & acorn nuts.
  12. Finally finished upgrading my solar arrangement. Dual 100w Renogy Eclipse monocrystaline panels, each feeding its own Genasun MPPT controller. Controller output switchable; can be combined to feed one bank, or split to maintain separate banks. On to the next project...

    Solar panel system, where to buy?

    It doesn't fold down; I didn't bother constructing it to fold because I never have a reason to fold it down. It just stays like that til the boat comes out of the water for the winter. Mounting hardware is off the shelf bimini bits: deck hinges, hinged rail clamps, a length of 1" SS tube, and eye tube end caps.

    Solar panel system, where to buy?

    You can fashion your own mounting solution as well with off-the-shelf hardware and stainless tubing. I did this with a 45w panel mounted to my stern pulpit: I used common SS bimini rail hardware and deck hinges, with a length of SS tube cut to length for the lower diagonal strut. This summer I'm going to expand on this idea with two larger (100w) panels mounted the same way on either side of the flip-down transom door.

    Proper technique for single handed jibes?

    Singlehanded gybing is kind of a drag on my boat because the end-boom sheeting, which is a 6:1 tackle, goes to a traveler that spans the cockpit immediately in front of the pedestal, and the bitter end leads out of the cam cleat at the bottom facing forward. This means that in order to sheet in all that line, I'd have to be standing in the forward part of the cockpit, facing backwards, with the mainsheet itself between myself and the wheel. I have not figured out a way to steer the boat facing backwards, handle the main, and avoid getting decapitated all at the same time. Oddly enough, my boat likes to gybe the genoa before the main. It usually collapses and I can gybe it to wing-on-wing well before the main wants to gybe. This does make gybing somewhat more elegant, I think. In light air, I stay behind the wheel, grab all 6 parts of the mainsheet and just help flip the boom to the other side and prevent all that loose sheet from snagging on the pedestal guard. In heavy air that maneuver would probably cost me an arm and a rig, so I tack. A boom-brake is on my wish list.
