    It's not very inspiring weather at the moment. Looked at the Aldi batteries myself thinking of doing that or having a Lithium battery I carry out in the dink. Not really sure on that yet, guess I need to get my boat back on the water first :)

    Well the glass set at possibly lower than 18 Celsius so the resin isn't too old, I taped some plastic bags over to keep the rain off. With the sun directly on the surface, temperatures probably get to setting pretty quickly. After reading Oldmulti's excellent articles pointing out the values of thin ply, stresses and loads, it is reassuring when building with recycled beachcat, cutting shapes from foam sandwich panels, and glassing them up to strengthen areas that are taking load, it is very similar to thin ply sort of. There is lots of similar detail except a need to build up right angles with Qcell/ microballoons to avoid hard to glass angles that make working out trapped air difficult where timber stringers would have been used for bulkheads and twist/ torsional resistance areas. Those posts of his are really informative; how successful tris have been made.

    One thing a fibreglass Tremolino has over all the other trimarans I've read about is the flange that goes right around the main hull. It makes the boat very dry. A largish cabin would be nice instead of the pair of coffins , but still you can't have everything. Yes green water can come up the forward deck and spill into the cockpit[exaggerated by the flanges] but it's rare and a nasty 5ft short steep chop you've plowed to do it, and it sheds immediately..

    I've cut out the shapes from left over maricat carcass for the dagger board case extensions and I can cut my baffle stations/semi bulkheads out from the leftover panels that are left while I'm waiting for good weather.
