Abstract
An embodiment of a launch/recovery device for both surface and underwater vehicles includes a plurality of driven wet-traction members arranged to form a low drag (e.g., water flow-through) ramp design. The wet-traction members provide traction even when wet between the water vehicle and the launch/recovery device. As a result of utilizing driven wet-traction members, the use of conventional hoists, special capture devices such as hooks and tow lines, and personnel located within the water to attach the capture devices to the water vehicle is eliminated. The wet-traction members provide both strength and flexibility to the launch/recovery device. That is, while the wet-traction members are strong enough to support the weight of the water vehicle, they are at the same time flexible enough to deflect a distance (e.g., about 6 to 15 inches) to accommodate a soft landing of the water vehicle on the ramp, while providing recovery forces and motion.
