Bobbie - That's a West Wight Potter 14, made by HMS Marine from the mid-60's to around the mid-70's. I had one of the earlier ones, #267, which, like the one on Craig's list, was made with a gunter rig, with wooden spars and a mast that went through the cabin top to bottom of the boat. I converted mine to a marconi rig with the mast stepped on the cabin top, and it looks like this one has been similarly converted. Les Clute
