Mast Steps


Mast Steps
Mast Steps, or Mast Feet, are used on Deck or Keel to secure the base of the Mast. Mast Steps are usually bolted through the Deck, or into the Keel. Some Deck Steps incorporate a means of attaching Turning Blocks for Halyards and other Control lines. Some Keel Steps incorporate a means of attaching various Tie Rods or Deck Tie-down Turnbuckles, attaching to the Deck or Deck Collar, to prevent Deck rise due to Rig Tension.
See, also Deck Collars, Mast Wedges, Mast Boots, and the unrelated, but oft-confused, Mast Stairs, for climbing.
