The boom engaging device comprises an elongated arm having a rotatable spool member which is positioned on and compressably engageable against the boom of the board sailing craft. The length of the arm supporting the rotatable spool is adjustable so that the device can be used by board sailors of varying heights. Moreover, the support arm is angularly adjustable with respect to the body engaging harness so that the boom serves to support the weight of the board sailor when the board sailor hangs out from the side of the sail surfing vessel to counteract the force of the wind exerted upon the sail and to control the direction of the sail craft but permits ready disengagement between the board sailor and the craft when the craft begins to capsize or the sail begins to fall.

Abstract: A device is provided for use with an actuator having an actuator shaft which indicates when the torque on the actuator shaft exceeds a predetermined limit. The device comprises a housing which carries a pair of limit switches. A shaft extension is operatively connected with the actuator shaft so that axial force on the actuator shaft, which is proportional to the shaft torque, is transmitted to the shaft extension. A hub and Belleville washer arrangement translates the axial force on a shaft into a proportional axial movement of the hub while a radially extending member from the hub includes a portion positioned adjacent the limit switch. Thus, when the axial force in one direction on the shaft exceeds a first predetermined amount, the radially extending member activates one limit switch which in turn is connected to an indicator.
