Abstract
A mast step for a kayak sailing rig is provided. The mast step supports a mast relative to a deck of the kayak at a desired angle to facilitate an optimum sail shape. The step also has a convex below a surface which contacts the deck, allowing the mast to be rotated forward or aft in use, and in particular allowing the mast to be rotated from an upright position to a flat position against the deck of the kayak.
Claims19
A mast step having a body with a mast mounting means on one side thereof for supporting a mast, and a deck contacting surface on an opposite side thereof for contacting the deck of a watercraft, vessel attachment means to attach the step to the watercraft, and the mast mounting means being arranged to mount a mast at a predetermined acute angle in a plane extending in a transverse direction relative to the watercraft, wherein the deck contacting surface is substantially convex.
A mast step comprising:
- a body with a mast mounting means on one side thereof for supporting a mast, and a deck contacting surface on an opposite side thereof for contacting a deck of a watercraft;
- and
- a vessel attachment means to attach the mast step to the watercraft,
- wherein the mast mounting means is arranged to mount a mast at a predetermined acute angle in a plane extending in a transverse direction relative to the watercraft, and
- wherein the deck contacting surface allows the mast to be moved between a substantially horizontal position and a substantially vertical position in a longitudinal direction while the body is attached to the watercraft by the vessel attachment means.
A mast step comprising:
- a body having opposing first and second surfaces;
- a mast mounting member connected to said first surface;
- a vessel attachment member for attaching the mast step to a craft, so that said second surface contacts the craft,
- wherein said body is rotatably movable so that said first surface is movable between a first position substantially perpendicular to a longitudinal axis of said craft and a second position substantially parallel to said longitudinal axis, said second surface contacting said craft at a plurality of positions between said first and second positions.
