Here's another old wooden hull for identification. I bought this one along with the RAF seaplane tender I posted previously.
This is a small cabin cruiser/motor launch which measures just under 17in long, and is built from plywood skin over a very minimal bulkhead/stringer skeleton.
It's definitely built from a kit (all the parts appear to be die-cut, and some have numbers printed on), and has a very "Aerokits" look to me - it's about the same size as their Sea Urchin and Nymph but the cabin shape and windows don't match either - it looks more like a mini Sea Scout (24.5in) than any of the smaller boats in the Aerokits range (the construction seems a bit flimsy by Aerokits standards too! - just three bulkheads including the transom, a keel, and two stringers). I'd imagine there were many other small wood kits of cabin cruisers around in the 1960s-70s period - can anyone identify which one it could be? It's all plywood, no balsa at all, so I'd assume it isn't a Keilkraft product.
I'm also planning to restore this one to working order, but though it looks superficially in better condition than the seaplane tender, it's been glued together with balsa cement which is now falling apart (certainly not watertight!). So, as with the larger boat, I've removed the deck and re-glued all the joints with aliphatic wood glue, and will later seal the interior of the hull with GRP resin, which as well as making everything fully watertight, should strengthen the rather flimsy hull structure.
