We source these as they are perfect for our Portage Pram and other small boats. They forgiving, strong, and affordable. Epoxy and Fiberglass make a strong economical mast. The 370 is roughly 12 feet long and weighs only 4.5 pounds. Nothing is easier to stow. The base diameter is 1.6” and if you are using it with our Portage Pram sail, the distance between the tack and the bottom of the mast is about 20 inches.
