The next type of board is the longboard or malibu (mal). The main difference in design is that the nose of the longboard is rounded. Other than that there is no real difference, though shortboards tend to have three fins and longboards tend to have a single fin.
Tall ships come in many shapes and sizes. The size of the vessel and its type are often determined by its mission and where it will sail. The first distinction between tall ships is the difference between a square-rigged vessel and a fore-and-aft rigged vessel. Square riggers have vertical masts that are crossed by yards, large wooden or steel beams that run perpendicular to the length of the shipâs hull. Sails spread below each of these yards. Large square-rigged vessels may have yards on one or more of its masts, and spread many acres of sails. They may also have some sails that run fore and aft, along the length of the ship. Fore-and-aft rigged tall ships have sails that only run along the length of the ship, from the bow toward the stern.
