Abstract
The gooseneck fitting disclosed herein carries a reel adapted for roll-furling a mainsail along its luff edge, the reel being positioned within a hollow mast with which the gooseneck fitting is used so the mainsail can be rolled up within the mast. The gooseneck fitting incorporates also a sheave for turning a line being drawn horizontally off the reel in a downwardly direction to a point of exit from the gooseneck fitting beneath the boom.
