Solar Panel Mounting On A Davit

Where I am located there are no sailboats that I've seen with solar panels mounted on there davit. All of the sailboats where I am smaller boats and most of them are under 24 feet. This is one of the reasons for my question.

I have a Garhauer Davit. It is the larger davit that they sell with the O.D. on the tubing being 1.25. I also have a double horizontal strut or stabilizer instead of a single one. The top arm of the davit is 44 inches long. This is where the dinghy would hang from. The first horizontal strut is about 4 inches from the end of the arm. The second strut is 22.5 inches further down. The width of the struts are 63 inches. I would like to install 2, 130 watt kyocera panels. ( I already own the panels ) The panels measure 56 x 26. The solar panel would extend about 14 inches past the end of my davit Is that ok ? Or are these panels to big ?
Thanks,
Paul

Those panel will be SUPER!!!!! Mount them so they are easy to remove for potential Huricane preparation. Not a big issue in Jersey I imagine..

Fair Winds,

Bill

How about contacting Garhauer and ask what they are rated for. And take into consideration how they are mounted. Beefy backing plates to spread the load?
You could have a strong davit but a weak installation

The davits are rated at 350 pounds, if I am not mistaken. The panels weight combined 66 pounds. I don't think weight will be an issue. My dink is a Walker Bay which weights 71 pounds. The davits have stainless steel backing plates. I believe the installation is more then fine. I even epoxied the holes I drilled and re drilled them. I was just concerned with the panels extending past the end of the davit. Garhauer suggested the addition of the second stablizer to aid in mounting the panels.

Thanks Bill, I plan on using them in the Caribbean. I hope that I don't ever have to deal with a huricane, knowing that I will. Good point.

But you might want to make the mounting brackets lockable, so your solar panels don't walk off in some isolated marina.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

One more question. With the solar panels on the davit, getting on & off the dinky from the stern will be impossible. So, mount a latter on the side and use a line to move the dinky over ? How are you doing this ?

Freesail,

I had aluminum angl iron fabricated to set the panel in. THere is absolutely nothing wrong with them being on davits. THat is how I see MANY boats doing it. You can also have them attach on the side via stanchion mounts. Be thoughtful about shading.

Let me see if I can post a pic so you can see the aluminum frame I had fabricated. I do not believe this was very expensive. It also allows more support of the panels and more security:




Sorry, this is the best pic I have. You can see the panels actually fit inside the angle iron.

Hope that helps.

Thats another idea. I have a good friend who is a metalworker. He may be able to make it for me. I, was looking at the mounts made by emarine.
CD, can you answer the question about boarding the dink ?
