Abstract

A power sailboat winch mechanism for the high speed gathering of running rigging line under initial low tension with final slow speed gathering of the same line under final high tension combined with line storage is disclosed. The winch mechanism includes two drums handling the line in series, these drums constituting a winding drum and a high torque drum. The winding drum is provided threaded to the bitter end of the line with a level wind for even distribution of the line along the drum. This winding drum provides initial rapid line take-up, tailing force to a high torque winch drum and line storage for the requisite amount of line used in the particular running rigging handled by the winch. A conventional high torque winch drum is provided between the winding drum and line load. This high torque winch is provided with surfaces to induce line climbing of the drum by conventional crowd climbing over the drum surface. This high torque winch spins free on a ratchet during high speed line gathering at the take-up drum, provides low speed high torque ouput for required final running rigging tensioning and has a proportional clutch release for letting line go under controlled tension for working of the running rigging.
