    Getting a Motorcycle Aboard a Sailboat

    Messed up my reply with the picture. It was supposed to be here in reply to yours.

    The first time I tried, I think I rigged a line to the bike in case I dropped it. But mostly I just re-set the mooring lines so that the bow overlaps the dock slightly, so there is no chance of the bike going in the water. I've only misjudged it once, I think, but was able to hold the bike upright and lift it back on the ramp.The Suzuki was stolen in September and I now have a Zero electric. That will be fun - totally different torque characteristics and no clutch.My most insane trip was getting it onto a small island by way of a tiny island - I brought the boat alongside the rocks at high tide with a log as a buffer, and had a four-foot gap to cross. Then I had to wait for the tide to go out to ride the bike to the big island. That was before I made the catamaran.

    It got a bit of rust on the handlebars where the ropes rubbed it, but otherwise not much. I wrap it in a tarpaulin if the sea's choppy and there's much spray.

    Lightweight solar panel (12V battery charger)

    Re. fibreglass, I don't know. I assume any other insulating material would work. I used GRP because I'm familiar with it. I understand about VOCs; one epoxy paint gave me a blinding headache so I made a positive-pressure respirator.The issue with the cells is minimum bending radius. All you need to do is mount them on a light stiff board (hence the honeycomb) and cover with a transparent waterproof material. It may be that acrylic would work, sealed with silicone sealant and secured with bolts. My solar kits suggest glass panels, which for me was too heavy and too fragile.I have since seen commercial panels for RVs becoming lighter and cheaper. Considering the work that is required for home assembly, I might just consider buying those for my sailboat project (still on hold).

    Good guestions. I think I used 2 layers of 4oz E-glass cloth from my local goindustrial store for the panel, then 1 layer of 2.5oz cloth to cover the PV cells. I'm not 100% sure.I'm not sure about the light absorbtion. There is about a 200% variation in open-voltage output of the cells I bought, so to get a good answer I'd have to carefully characterize a particular cell then measure it again after encapsulation. I did some crude measurements like that but forget the answer, beyond "it worked". The potting resin is completely transparent to visible light, and I don't think that well-wetted glass absorbs much light. I'd assume it would be at least as good as the epoxy some commercial panel manufacturers use. Years ago I made a motorcycle headlight lens with glass mat, which was...
