Mast Step Hinge Assemblies

A Hinged Mast Step simplifies raising the Mast on smaller boats. Most assemblies shown here are 'Universal', designed to be bolted to standard Mast Steps, usually Cast Aluminum, allowing the Mast to pivot on one of the horizontal Pins. Assemblies are short enough that it is usually not necessary to modify existing rigging to add them to your boat. The size of your Mast Section will determine which units are suitable for your boat. If you require a new Mast Step, hundreds are listed on-site under the specific Mast Section that they fit. For details, See: Spars. Please Note: Many other Hinged Mast Steps have been produced that are specific to a particular Mast Section. Those are listed on-site under the specific Mast Section that they fit. For details, See: Spars.
