Notes: Commissioned by members of the Hull Y.C., (near Boston, MA USA) and also known as the HULL SEA BIRD. The class didn't outlive World War II, but a single example was being restored in 2008. Thanks to Peter, who hosts an excellent website dedicated to the SEA BIRD, for supplying information on this yacht.\n* Plans include 15 lbs of lead ballast.
