difference in longboard shapes
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.
Most boards measure 84 to 150 centimetres (33 to 59 in) in length while widths vary from 22.8 to 25.4 centimetres (9.0 to 10.0 in). There are several longboard shapes, such as pintails, swallowtails, flat-nose riders, drop-through decks, drop decks and boards with the same shape as a standard skateboard.
