A launch and recovery system for a towed body is provided in which uninflated air beams extrude from winches where the beams enter a deployment frame and are inflated. Sealing rollers near the winches seal the air beams when the desired length of the air beams is inflated. To deploy the towed body, a positioning cart moves along the inflated air beams from an end of a deployment frame. A translating arch moves from the forward to the aft end of the positioning cart on the rails to where the tow body is released from the capture boom and swing support. The positioning cart can retract back into the deployment frame when not in use.

Variable length inflatable ramp launch and recovery system

An inflatable launch and recovery system for a towed body is provided. The system is containerized for ease of transport. A container houses a tow body, tow cable, a winch, winch controls, an inflatable ramp, deployment and retrieval equipment, power junctions and air line connections. Inflatable arch shaped tubes and spacer fabric form the ramp structure from which the tow body can be launched and recovered. The ramp can be ballasted to provide hydrodynamic stability and to provide sufficient system depth to accommodate retrieval of towed bodies operating below a liquid medium surface. Additional control can be achieved using inflatable or rigid fin elements or downward lifting surfaces. A rigid clamping fixture connects the ramp structure to the vessel. A snubber element dampens vibrations and transient tow loads.

Inflatable launch and recovery system

The invention as disclosed is a towline guide clip, an apparatus that can hold a towline in place as it is dragged behind a large host marine vessel attempting to recover a small marine vessel. The towline guide clip is designed to gradually release the towline when a small marine vessel grabs hold of the line. The additional dragging force of the small marine vessel pulls the towline out of the towline guide clip so that the towline can then be reeled in by a winch.
