ABSTRACT:
A transporter unit is used for abutting against a genoa car or lead block on a track on the starboard or port side of a deck of a sailboat to lock or move the lead block to adjust the jib sheet angle while sailing. The unit is slidably engageable on a modified track having a series of gear grooves to mate with a worm gear mounted on the unit. The unit is moved on the track by turning a shaft with an attached worm gear mounted in the unit. The worm gear cooperates with the track. The unit has a slidable carriage. The bottom of the carriage has a channel which mates with the modified track. The top of the carriage has a rectangular cavity onto which is mounted a rectangular housing. The cavity on the top of the carriage has a rectangular opening to provide access to the track for the worm gear. The carriage has a pair of inboard and a pair of outboard knuckle projections. There is a common bore through the inboard knuckles and the housing into which a quick release pivot pin is secured. The outboard knuckles and the housing have a common bore into which a pivot pin is secured. The housing is openable and closable. The underside face of the housing has a rectangular cavity. There is a medial bore in the underside for mounting the rotatable worm gear and shaft.
