ABSTRACT:
A bowsprit, or spar, for supporting a spinnaker sail at the front of a sailboat is mounted on the deck of the sailboat. The bowsprit is retractable and extendable in telescoping fashion and includes a rope or tack line extending from the forward end thereof that connects to the corner or tack of the spinnaker sail. The aft or back end of the bowsprit is clipped to the mast and may be unclipped therefrom and secured to the deck so as to position the bowsprit at an angle to the boat to present the spinnaker sail to the wind. The present bowsprit is mounted along the midline of the boat and extends through a swivel bridle that connects the forestay to the deck. Extension of the bowsprit is accomplished by pulling a line connected to the inner pole of the bowsprit and passing around a pulley so that the inner pole slides out to an extended position from the outer sleeve of the bowsprit.
