PCT No. PCT/GB89/00901 Sec. 371 Date Mar. 14, 1991 Sec. 102(e) Date Mar. 14, 1991 PCT Filed Aug. 7, 1989 PCT Pub. No. WO90/01432 PCT Pub. Date Feb. 22, 1990.A trailer for catamarans, which can also function as a launch trolley, uses a lever mechanism to actuate a pivotally mounted lifting arm (20) which engages the front cross beam (44) of the catamaran. The reaction thrust is transmitted through the frame to a second lifting arm (22) engaging the rear cross beam (42), whereby the weight of the whole boat is transferred to the trailer frame (14). The lever mechanism is self-locking in its raised position. A roller on the actuating lever provides a moving pivot point whereby a cam-like action is obtained. |
