Carbon monoxide (CO) is colourless, odourless, and potentially fatal. It can come from engine exhaust, diesel heaters, gas cookers, petrol generators, charcoal barbecues, or another vesse...
Engine failure is rarely just a mechanical problem; it is a navigation problem. The first action is to keep the vessel safe: sail if possible, reduce sail if overpressed, keep clear of a...
Steering failure needs immediate control of speed and direction. Reduce sail or engine power, keep the vessel away from hazards, and rig the emergency tiller if fitted. Brief the crew bef...
After grounding, stop the engine and check crew safety first. Then assess hull damage, bilges, keel/rudder condition, tide state, weather, and position. Do not automatically motor hard as...
Flooding is time critical. Start pumps, find the source, assign crew to damage control, and prepare a distress call. Shut seacocks if a hose has failed. Use softwood bungs, collision mats...
A dismasting or major rig failure can injure crew, damage the hull, and foul the propeller. Account for the crew, stop the vessel if possible, keep clear of the rig, and check whether the...
Towing loads can be extreme. Use strong points, a bridle where possible, long towlines for shock absorption, and chafe protection. Keep crew away from loaded lines and never stand in a bi...
