A person goes over the side. From that second the boat is moving away from them, the propeller is still turning, and everyone on board is looking somewhere different. What happens next is decided in the first minute, and that minute goes better if the plan was already in everyone's head before it was needed.
Shout "man overboard" with the person's name. A name gets a reaction that a general shout does not. Then point with a straight arm and do not look away โ not for a rope, not at the throttle. A head in choppy water disappears between swells, and once you have lost sight you are searching, not rescuing.
Get the engine to neutral first. A spinning propeller is the most dangerous thing in the water near a swimmer, and on a small boat the stern is exactly where someone ends up. Once the propeller is stopped and the watcher still has the person in sight, turn back bow-first and slowly, keeping the person on the same side of the boat all the way in.
Do not reverse onto them. Ever.
Come in from downwind and up-current so the boat drifts toward them rather than over them. Kill the engine or leave it in neutral alongside: a boat with a stopped propeller is a rescue platform, and one with a turning propeller is a hazard. Never jump in after someone. Untrained rescuers become the second casualty far more often than people expect, and then there are two in the water and nobody driving. Reach with a boathook, a paddle, a rope or the ladder โ something they hold and you pull.
Most people cannot climb a ladder in wet clothes. Use the stern ladder, or a loop of rope under the arms to take their weight, and lift with your legs, not your back. Once they are aboard, get the wet clothes off, wrap them in anything dry and keep them out of the wind. Warm them slowly: no hot shower straight away and no hard rubbing of the limbs. Kuwait's water in winter is colder than it feels, and someone who has been in it for a while stays confused and shivering well after they are safely on deck.
Before you leave the marina on the next calm day, run it once. Someone shouts a name, one crew member points and counts, another throws the ring, the driver goes to neutral and marks the position. Do it at walking pace with a bucket standing in for the casualty. Ten minutes of practice means the real one is not the first time anybody has done it โ and you can check the sea state in the B7R app before you actually leave the dock.
In an emergency there is no time to hunt for the right screen. The B7R app is free on Google Play, with sea state, tides for Shuaiba and Shuwaikh ports, navigation tools and an SOS button for emergencies: get it on Google Play.
