Mast Stairs


Mast Stairs
Mast Stairs are mounted on the Mast to provide a foothold, allowing easy access to higher parts of the mast than you can reach from the deck. Frequently used to reach the top of the sail cover or the sailgate, some models are also suitable for attachment of halyard shackles. On Cruising Rigs, Mast Stairs are sometimes mounted all the way up the mast, allowing easy access to the masthead, as well as an excellent viewpoint for navigating reefs. Sometimes mistakenly referred to as Mast Steps, Mast Stairs (that people step on) should not be confused with those items that Masts step on.
