Balancing system for opposing heeling and drift of single hull sailing boats - has two vertically slidable floats applied to hull, lee side float being operated by lateral thrust on sail

摘要

The system includes one or more laterally tiltable masts, both lateral sails connected to hoists, and pulleys and wires to transmit the force acting on the sails to boat heeling and drift control systems. The boat drift and heeling balancing systems include two properly shaped floats, the lee one of which slides to the hull along mechanical guides from top to bottom, progressively dipping into the water. The floats are shaped in order that, when they are dip, they oppose both the boat heeling and boat drift. The float dipping occurs by the action of the wind's power acting on sails. It is received by a system of wires, pulleys and hoists and requires no intervention by the crew.
