J/30 Class Association Forums J/30 Forum The Boat, Sails and Equipment Moisture Issue

Just do a Google search for "balsa core material". There are several suppliers. You should expect to pay $25 - $30 for a piece of 3/4" X 2' X 4'. I purchased some from a place in WA. They were fast and helpfull on the phone. If you were in Alaska I would be glad to give you my leftovers from the project last summer!
