Think of how much foaming you see when you're refueling and how quickly you depart the fuel dock on a busy day.

Been thinking boat projects here as well. Yesterday I picked up a sheet of foam, a pail of vinylester and some fiberglass mat ready to start my rudder project. A couple weeks ago I built a jig for the rudder stock and delivered it to the aforementioned welder. Hope to see the bronze skeleton for my new rudder by the weekend.
