If the boat does invert, both crew and helm move to the windward side and lean back on the centreboard, using a jib sheet (or righting line) to assist if necessary. Once the centreboard is within reach the heavier person should climb onto it and bring the mast horizontal, pointing downwind.
Once the boat is stable in a horizontal position, the lighter person goes into the boat via the stern to recover the spinnaker and release the kicker and mainsheet. Free the spinnaker halyard and carefully pull the downhaul to lower the spinnaker into the chute. If your boat has bags instead of a chute, gather the spinnaker using the upper sheet and one side of the sail, stowing it in the upper bag.
Safety first. Stay in contact with the boat but take care if the boat is inverting.
安全第⼀。在船只倒扣时,不要远离船,但要注意安全问题。
Note that, while this procedure will reduce the risk of the boat inverting on top of a crew member, some boats are more prone to inversion than others. Be aware of the risk of re-inversion at all times. One or two designs may even invert with someone fully on the centreboard.
