Abstract: A spar-end boom fitting, comprising a first and a second boom receiving member each having a boom receiving bore therein and each being joined by a connecting member with the connecting member forming with the boom receiving members a spar-receiving indentation and having a first and a second lashing line passage therethrough, and a jam cleat formed radially along the outer circumference of one of the boom receiving members, including a groove, having a pair of opposed rows of teeth. In addition it is disclosed that the boom receiving members have a plurality of parallel radially outward extending ribs and an interconnecting longitudinally outward extending spine and the groove is formed between a pair of the ribs. Further the disclosure includes the spar receiving indentation being covered with a resilient foam material which will conform to the shape of the spar. Still further, the disclosure includes an up-haul line locking mechanism formed in the connecting member.

Abstract: A base for the spar, i.e., mast, of a wind-propelled vehicle useful for attaching the spar, i.e., mast, to the universal joint which universal joint is further attached to the wind-propelled vehicle. The base has a cylindrical bore for receiving the spar, i.e., mast, in the upper portion thereof and the lower portion has an axially-located bore for the passage of a bolt which connects the lower end of the spar, i.e., mast, to a portion of the universal joint, and two line passages extending through the lower portion generally perpendicular to the longitudinal axis of the base, each having a pair of upper surfaces which slant inwardly downward towards the center of the passage and define a pair of grooves in the lower portion, with one of the grooves on one of the passages having a plurality of teeth on the opposed side walls thereof which grip and hold a line, acting as a jam cleat.
