Telescopic mast for sail-powered vessels

Abstract

The invention relates to a telescopic mast device (1) for a sail-powered vessel, the telescopic mast device (1) being erected along a specific elongation axis (O1) and comprising: - a fixed section (11) intended to be positioned above an upper deck (42) of the vessel; - a plurality of movable sections (10, 10A, 10B) coaxial with the fixed section (11), each upper movable section (10, 10A, 10B) – called the upper section (10B) – being slidably mounted in the directly lower movable section (10, 10A, 10B) – called the lower section (10A) – relative to the specific elongation axis (O1) of the mast;- angular indexing elements (2) configured to constrain a rotation of each upper section (10B) relative to the lower movable section (10, 10A, 10B) located opposite, relative to the proper elongation axis (O1), the angular indexing elements (2) comprising at least one indexing wedge (22) secured to an upper part (102) of the upper section (10B), the at least one indexing wedge (22) collaborating with at least one indexing rail (21) secured to the lower section (10A) located opposite said at least one indexing wedge (22).
