ABSTRACT:
Steering apparatus for a boat includes a pair of laterally spaced rudders, each having a forwardly directed control arm. In each of three embodiments a tiller arm is employed. In one embodiment a pinion gear is journaled for rotation on the tiller arm, being in mesh with two gear racks each of which connects with a control arm. In a second embodiment, the tiller arm shifts a pair of pulleys about which is entrained a rope or cable, one control arm being clamped to a cable section at one side of the pulleys and the other control arm being clamped to the cable section of the other side of the pulleys. In the third embodiment, a pair of hydraulic cylinders have their closed ends pivotally connected to the tiller arm and their piston rods connected to the control arms. The open end of one cylinder is hydraulically coupled to the closed end of the other cylinder, and the closed end of said one cylinder is hydraulically coupled to the open end of said other cylinder.
