So your boat's flipped. First thing's first—don't lose your head. Your number one move is to stay with the boat. I know it sounds counterintuitive when everything's upside down and water's rushing in, but that hull is your best friend right now. It floats. It's visible. Rescuers can spot a boat way easier than some person bobbing around. Everything else flows from this one decision. Here's the thing about boats—they're big. Even half-submerged, they keep you afloat and block some of that soul-sucking cold water. Hypothermia kills fast. The vessel's also packed with stuff you might need, like flares or a radio, but only if you're close enough to grab 'em. There's another reason too, maybe the most important one. Search crews scan for boats, not people. Okay, you're with the boat. Now what? Here's the order of operations, and it matters: Where you plop yourself matters more than you'd think. Depends on what you're on: People do dumb stuff when they're scared. Don't be one of them. Seriously: Depends. Water temp, your body, what you're wearing. In 50°F water—which is plenty cold—maybe 1-3 hours with a life jacket. Without one? Much less. The trick is getting out of the water as much as you can. Sit on the hull. Stay dry-ish. Then you're down to your life jacket and whatever floats. Make sure that PFD's tight. Grab debris. If there's a group, huddle up—it keeps you warmer and makes a bigger target for rescuers. Honestly? Probably not. Unless it's a tiny boat and you've done this before, forget it. Big boats don't flip back easy. They're stable upside down. Use 'em as a platform. Don't waste energy trying to play hero. Q: What is the first thing to do if a boat capsizes? A: Stick with the boat. Don't swim off. Use it to float and signal. That's it. Q: How do you signal for help from a capsized boat? A: Whistle, horn, mirror, anything bright. If you've got an EPIRB or VHF, channel 16. Wave your arms like a crazy person. Q: Can you survive a capsize without a life jacket? A: Possible but way harder. You'd need the boat or debris. A life jacket? That's your best bet by a mile. Q: How do you prevent hypothermia after a capsize? A: Get out of the water. Sit on the hull. Keep clothes on. Don't move much. If you're in the water, curl up—knees to chest, arms crossed. That's the HELP position.What should you do first on a vessel capsize
