Potter! I had the HMS 18! It was the Potters big brother. I sailed the s&@" out of it. I installed a QME wind vane, an RDF, a CB radio (I was broke) and a war surplus two man life raft. I sailed it out to the Channel Islands 60 some miles off shore routinely. It was when I was young and dumb! Having said that it was a hell of a lot of fun. There is a new one on our dock at our club but they stretched it another foot to 19 feet. It's huge compared to the potter.
