Latest Patents

Donaldson's latest patents include the "Mast track with external headboard car" and the "Sectionalized mast track." The mast track with external headboard car features luff extrusions that solve problems of batten chafing and friction locking. These innovative luff extrusions provide batten end receptacles with channels for headboard cars. They also absorb wind-generated compressive forces exerted by the battens on the batten pockets, eliminating the need for sail slides. The sectionalized mast track addresses issues associated with furling and reefing sails on large yachts. This inventive design includes mast track sections secured to a mast with hinges, allowing for easy removal of individual sections. The cross-section of the mast track absorbs wind-generated compressive forces, reducing chafing and enhancing functionality during sail operations.
