ABSTRACT:
A sail boat boom control system provides braking forces for restraining movement of the boom during down wind sailing or sailing with a quartering breeze. The system comprises a boom restrainer loop attached to the boom and resiliently tensioned, pivotally mounted friction device which is adjustable to apply friction forces restraining movement of the boom loop, thereby providing the braking force on the boom. The friction device is adjustably controlled by a control line extending to a position where it is easily operated by the helmsman or other crew. A quick-release device releases the control line when required to allow the friction device to move to a position in which the boom is free from restraint. Deck-mounted and mast-mounted friction control devices are disclosed.
