If someone falls overboard, follow these procedures to get them safely back onboard.
If someone falls overboard from a small open runabout, make sure that everyone onboard keeps the person in sight while you manoeuvre to pick them up.
In bigger craft and when operating offshore, throw over a lifejacket or marker immediately. If you lose sight of them this will act as a starting point for a search.
Keep the person in sight at all times and tell passengers to act as lookouts. Quickly establish your position either by reference to shore marks or by a GPS position. An accurate position will be essential if the search requires outside assistance.
Once the person is alongside, stop the engine and make sure that the weight in the vessel is redistributed before attempting to bring them on board. Consider bringing them over the stern if the vessel is unstable.
