you to steer. Generally boats will maintain a course to give the wind at 30 degree to the Port Bow. The preferred area to conduct winching operations is normally the port quarter. This affords the pilot visual contact with both the boat and the winchman.

In the event of a helicopter rescue situation, the following points should be noted and followed:

▪Prepare well in advance of the

arrival of the helicopter; ensure crew are well briefed on correct procedures.

▪A sailing yacht may be steadier

motor sailing with a reefed sail. It stops the mast swirling around, making it easier for the winchman to land on board. However, every opportunity should be utilised to discuss the best approach with the helicopter crew before the helicopter gets close to the vessel, including consideration of the potential impact of downdraft.

▪Clear all obstructions on deck

prior to the arrival of the helicopter. Ensure there are no items of loose or moveable gear on deck.

▪Be prepared for the helicopter

downdraft which can be strong enough to knock a crew member off their feet or cause a leeway effect on small craft.

▪Due to the risk of static build-up

from a hovering helicopter, follow the pilot’s instructions exactly with regard to the earthing of a static discharge wire prior to placing the winchman on board. The wire is usually dropped into the sea to discharge static prior to commencing the operation.

▪All operations will be directed by

the crew of the helicopter – follow all instructions.

▪Liaise with the helicopter before it

nears the vessel due to the noise of the helicopter and the potential impact of downdraft when the helicopter is operating with or adjacent to the vessel.

▪Under no circumstances should

the winch line be made fast at any time to the boat.

▪Do not be distracted by the

noise of the helicopter overhead. It may be necessary to have a crewmember positioned inside the boat to maintain radio communications with the helicopter due to the excessive noise on the outside decks.

▪On arrival of the winchman on

board, that person will assume command of all subsequent operations. Follow the instruction given at all times.

▪Do not fire parachute flares when

a helicopter is operating in the vicinity.

▪The pilot will give specific

instructions regarding the course and direction he/she may wish
