There were three moored on the pontoon of Swansea Industrial museum last summer. They are not part of the museum, I think they are given free mooring there to improve the scenery, so they are probably still there. I think Kindly Light and Marguerite were there. Peggy is usually at Bristol, at Lunds marina; Breeze is falling to pieces at Porlock Weir, there was one at Gloucester [ Hirta?]
I think that other correspondents may be missing a fairly large point; The cutters built by Sam Morse were designed by Lyle Hess in California, made of fibreglass, and about 26ft long on deck. They are not to be confused with the original Pilot Cutters, as they have more in common with the Falmouth Quay Punt.
