Boston Whaler is an American boat manufacturer located in Florida. It is operated as a subsidiary of the Brunswick Boat Group, a division of the Brunswick Corporation. Boston Whalers were originally manufactured in Massachusetts, but are currently manufactured in Edgewater, Florida. Dick Fisher graduated from Harvard University in 1936. He ran a company building small, lightweight boats out of balsa wood. He designed a rowboat and got the materials to build it, but he never completed it. In the 1950s, polyurethane foam, a stiff, lightweight, buoyant material, was invented. Fisher imagined it as a replacement for the lightweight balsa pine used in small boat construction, and in 1954 he constructed a small sailing dinghy filled with the foam, with a design similar to the Sunfish. He showed the finished product to his friend, naval architect C. Raymond Hunt. Hunt recognized potential in the process, however he did not feel the design was particularly suited to sailboats. Instead, he created a design based on the Hickman Sea Sled featuring a cathedral hull.
