I've been sailing on the wet stuff for 20 plus years. Heard about ice boats a number of yeas ago. I made a very simple one using a sunfish sail, got hooked with the idea that a better boat was better sail. Started looking for a used one for sale. Found what I was told is a "Stobstead Hull #4" by the seller. It is a simple tee with tensioned/arched hull and bowed cross member. The rigging is made by Stobstead Sails out of Old Saybrook, CT. Have any of you heard of such a boat? Looking for information, thx. The next step up is a D/N. Living in CT, sailing the lakes in the winter and the L.I.
