So your boat's flipped over but it's still floating. That's actually not the worst scenario you could be in, believe it or not. Unlike when a boat's actually sinking, that overturned hull gives you something solid to hang onto plus an air pocket. Your chances of getting rescued just shot way up. But here's the thing - panic and making dumb decisions will kill you way faster than the water will. Let's walk through what you actually need to do. First thing? Stay with the damn boat. I mean it. Do not - I repeat do not - try swimming for shore. I know it looks close but it's not. It never is. That boat is massive compared to you, rescuers can spot it from a mile away. Plus it's keeping you afloat and protecting you from the elements. If you're stuck under the boat, here's the deal - stay calm. Seriously, freaking out just burns through oxygen faster. You've got maybe 30 to 60 minutes of breathable air in there depending on how big the boat is and how many people are with you. Find the highest point of the cabin or hull, that's where the air pocket will be. Then work your way out systematically. Try the door or hatch first. If it's stuck, look for a window or any gap in the hull. On smaller boats you can often just push yourself out from under the edge. And if you can't find an exit right away, stay put in the air pocket and bang on the hull. Someone might hear you. Honestly? It depends. Small sailboats and kayaks? Yeah, they're built for this stuff. Bigger boats? Don't even try it without help. And trying to right a boat that's not designed for it? That's how you sink it. If you're going to try righting it - and only if it's a small boat - get everyone clear first. For a small sailboat, stand on that centerboard and lean back hard. Kayak? Use a paddle float or get a buddy to help. If it doesn't work easily, give up and just stay with the hull. Look, preparation is everything. You don't want to be scrambling for gear when your boat's already upside down. Here's what you should have on you or easily reachable at all times. Depends on water temp, weather, and your shape honestly. Warm water above 70°F? You could last days on that hull. Cold water below 50°F? Hypothermia hits in 30-60 minutes. But getting out of the water onto the hull buys you way more time. Get on top of the hull if you can. That air pocket inside? It's a last resort if you can't get out or conditions outside are nasty. On top you're visible to rescuers and you avoid carbon monoxide poisoning from engine fumes or fuel leaks inside. Smell gas or diesel? Get away from the boat fast but keep it in sight. Fuel vapors can ignite from a spark. If you're on the hull, move to the front or back away from the engine. Don't use any electronics or lighters. Use everything you've got - visual and audible. Wave a brightly colored PFD or shirt in a big "X" pattern. Whistle three short blasts (that's the universal distress signal). Nighttime? Flashlight or strobe. Got a VHF radio? Channel 16, say "Mayday, Mayday, Mayday" followed by where you are and what's happening.What to do if a boat capsizes but stays afloat
What is the first thing to do when a boat capsizes?
How do you get out from under a capsized boat?
There's this acronym "SLOW" that actually helps: Stop moving so you don't get disoriented. Look for light where openings are. Orient yourself by following bubbles - they always go up. Wait for your eyes to adjust before swimming out.
