A 250-lb fiberglass sailboat is a standard 14' dinghy with a main and jib like a C & L 14 or a Hobie 14 which have wide hulls and using three foam noodles is a good way to roll it down a smooth embankment. It works very good and the noodles can be re-used many times. Is similar to using straight tree logs for rolling a heavy object like a granite block weighing a ton. Foam noodles would probably work with something weighing 500-lbs like positioning an empty hot tub into place.
If only foam noodles were available at the time they could have made it much easier for the ancient Egyptians to build their great pyramids .....
