Module 4 - Safety
Helicopter Rescue
Maintain the listening watch on Channel 16 or the frequency specified and repeat the aircraft's requested course, speed and working area. Clear loose gear before the helicopter arrives and keep unassigned people away from the winching area. Do not invent a universal heading or stop the vessel unless directed; the safe profile depends on the aircraft, wind, sea, yacht and casualty.
A hi-line is a light line used to guide the winchman or strop when the helicopter cannot hover directly overhead. Tend it, keep it clear of obstructions and feed or recover slack as directed. Never secure a hi-line or winch wire to the yacht and never wrap it around a person or hand.
The wire and the person being lowered may carry a dangerous static charge. Do not touch either until earthing or discharge has occurred and the aircrew or winchman directs contact. Do not assume one universal instruction to touch a particular part of the yacht first.
Once aboard, the winchman controls the transfer. Keep the working area clear, continue the requested course and speed, and report any fouled line or new hazard immediately. Never cut a fouled wire unless the helicopter crew directs it.
- Never attach the helicopter wire to the boat
- Wait for earthing or discharge and the aircrew's direction before touching the wire or person
- Clear the deck of loose gear
- Follow the winchman's instructions
- Communicate on VHF as directed
Watch for this: Tend a hi-line as directed and keep it clear of fittings. Never make it fast, stand in a bight or wrap it around a hand; it must remain free for the aircraft to move away.
