Home build of a Hadron H1 singlehanded dinghy

Aindriu McCormack has sent in some photos from his home build of a Hadron H1, a singlehander with a very unique look: a central longitudinal buoyancy tank and no side buoyancy.

I bought a set of plans from Keith Callaghan which were very reasonably priced and also came with some basic instructions. The dinghy is made from marine ply, sapele, western red cedar, epoxy resin and some carbon fibre cloth.

The four-plank hull was built upside down on MDF frames, and only just fitted in my garage. Once the basic hull was finished, faired and painted with primer it was removed from the frames. Now the right way up, the rest of the dinghy structure was completed quite slowly (mostly in the evenings).

I found that I really slowed down when I got to the cutting and fitting of the veneered marine ply on the foredeck; I was worried about making a mistake that couldn't be covered in filler and paint. I did make a few... but I think I got away with it.

With all of the woodwork completed I got the boat sprayed; while it was out of the garage I made the cedar/carbon fibre foils.

The boat is now back in my garage and I am very slowly fitting it out.

With Andy working for Selden, we don't expect too many surprises when we see the spars he chooses to fit at the end of his build. Remember we want to hear YOUR stories of boat repairs, renovations and invention too.
