Here's a rough outline and history of the various models of UK Potters according to my limited knowledge:

"A-Type" is the name now used to refer to the original plywood West Wight Potter designed by Stanley Smith and built by West Wight Plycraft, Ltd. on the Isle of Wight.

The B-Type is the first UK fiberglass Potter and looks much like the first U.S. Potters, like my own, and it was built during the same period, in the late 60s. West Wight Plycraft was apparently renamed West Wight Marine. A UK B-Type brochure indicates HMS Marine in the U.S. and West Wight Marine in the UK were cooperating during this period, and the U.S. boats used the same WWP sail emblem as the UK boats. It is known that Herb Stewart in the U.S. developed the fiberglass version of the Potter for the U.S., and he may well have provided a duplicate mold to West Wight Marine for the B-Type.

The C-Type and its variants seems to have been produced over many years and by more than one company, starting with West Wight Marine, which also made the Glass Slipper, apparently an export version that appears to be the same as the C-type Potter, but did not use the Potter name or emblem. One ad for a C-Type Potter shows the manufacturer as West Wight Laminates, also on Wight and possibly the same company renamed. There was no Potter similar to the C-Type built in the U.S, and Stewart's HMS Marine had stopped using the UK WWP sail emblem when the U.S. Gunter rig was discontinued.

The Nova: Bruce Hood visited the Potter Boat Company in Dorset in 1987. The boat was then being called the West Wight Potter Nova, and a 1991 ad shows a quadrilateral main like the U.S. Potters, but it was still the C-Type configuration with the stepped cabin and wide cockpit (no side decks). The C-Type had quarter berths instead of a V-berth, but I'm not sure that was true of all versions.

The D-Type: A magazine review of the D-type gives the manufacturer as the Potter Boat Company, but now located in Durham City, not Dorset. The D-Type was apparently also called the Ghia. A junk rig was an option, but I'm told only a couple junk-rigged Potters were sold.

The Potter AX: Production of the C/D-Type models had apparently ceased before Martin Pook in Dorset came out with the wood and epoxy Potter AX. It had an advertised length of 15' 2" and a quadrilateral sail similar to the U.S. Potters. Reportedly, Pook developed a sensitivity to epoxy and discontinued production after only a few boats were produced.

A Brazilian company has recently been formed to produce the Potter AX in that country, and the first boat is undergoing tests in 2005.

The E-Type: The most recent UK Potter was the E-type, manufactured by PotWight Marine. It had a fiberglass hull and a wooden cabin that resembled the A-type cabin with the reverse sloping front. I understand the boats were high quality but expensive, and only a few were sold before production was discontinued. The forward slant on the cabin of the original Smith design ("A-Type") and the E-Type was probably intended to deflect spray downward to minimize the amount blown over the top of the cabin and into the cockpit.
