A self-propelled watercraft launch and retrieve vehicle is disclosed. The vehicle comprises a central chassis 1 which includes a cradle for carrying a boat. The boat may be launched from and retrieved onto the cradle from a rear end of the chassis. The chassis also comprises a forward part mounting at least one pair of forward wheels 12. A rear part of the chassis mounts at least one pair of rear wheels. The forward and rear parts of the chassis are coupled for limited movement relative to one another about an axis which extends longitudinally of the vehicle. At least one pair of wheels are steerable under remote control. Hydraulic motors are associated with each of at least one pair of forward wheels and at least one pair of rear wheels for driving the wheels. A prime mover or electric motor and a hydraulic pump or pumps driven by the prime mover are mounted at or towards the forward end of the chassis and elevated above the chassis. The hydraulic pump or pumps power wheel hydraulic motors. A hand held remote control unit is operable by an operator standing beside or near the vehicle to cause the vehicle to move forward or to reverse and to steer the launch vehicle to the left or right.
