The mast supports fore-sails that may consist of a single jib, multiple staysails, or a crab claw sail. The mainsail is either small or completely absent. Mast-aft rigs are uncommon, but are found on a few custom, and production ...
Topmast. A traditional ship's mast, consisting of "lower" (i.e. Main-, Fore- or Mizzen-) mast, topmast and topgallant/royal mast. The topmast is highlighted in red. The masts of traditional sailing ships were not single spars, but were constructed of separate sections or masts, each with its own rigging. The topmast is one of these.
