Abstract
The apparatus and method of the present invention provide a crewmember with the ability to lubricate the sheaves at the head of a mast of a contemporary sailing vessel from the deck. A cylinder that may be secured to existing halyards is filled with a lubrication fluid. The cylinder is raised in the usual manner and, once at the top of the mast, a plunger deploys the lubricant through a bifurcated stem to each side of the sheave.
