Abstract
A mechanism to raise and lower the sail of a boat includes a headcar movably secured to a mast of the boat and a headboard affixed to the sail. A pulling force applied to a halyard raises the sail and causes the headboard to engage the headcar. When the sail is lowered, the headboard disengages from the headcar so that the sail furls flat on the boom.
