ABSTRACT:
For a sailboat, a constant force spring reel is used to balance the force in a control line used to establish the angle of the sail with respect to the boat. The spring exerts an essentially constant force on the control line whereby the sail is allowed to move to leeward or windward in response to wind changes to maintain an essentially constant sail force on, and angle of heel of, the boat.
