It is a Stone’s built yawl – I can’t remember whether it was built by Hugh Cater before he moved to Bantham, but I think it might have been.
We also used to sail from Bantham in my grandfather’s yawl (either 52 or 54), which had an inboard Turner engine – apparently they built her as a test, and then decided “Never again!”
The boat I really miss is our old Bantham boat; for anyone who’s heard of them, she was one of the first 4 built, and had the original bamboo mast and spars, and the copper buoyancy tanks. We used to race her against the yawls in the handicap races at Bantham, and she was quite a handful. Hugh Cater was banned from racing her because he always won, and the people we sold her to had to get a smaller suit of sails made because she was too much for them!
