ABSTRACT OF THE DISCLOSURE A sailing boat mast of simplified and standardized constructional design comprises a tubular section and an ancillary component comprising a masthead which is welded to the section. The masthead comprises anchoring means, forming an integral part thereof, for the standing rigging, the anchor- ing means comprising a duct defining a flared-out and rounded inlet orifice in which is mounted a knuckle-joint assembly for retaining the end portion of standing rigging, the end portion being provided with a terminal enlargement which corresponds in shape to the flared-out portion. The masthead also comprises a casing welded to the tubular section and a removable headpiece. The casing is provided with means for anchoring standing rigging, and slots receiving supporting axle-pins of sheaves and horizontal rollers, and with lateral guiding means for running rigging. The head-piece is adapted to lock the sheave pins in position and defines partition-wall means. The lateral guiding means are adapted to receive a spinnaker halyard and comprise friction members cast in one piece with the casing and head-piece. The mast-head casing is provided with a plurality of slots to receive each sheave pin and each roller, whereby the sheave pins and rollers can be positioned within the casing as a function of size of the mast on which the casing is mounted and as a function of inner and outer utilisation of the halyards.
