Fishing boat can't handle rough weather?

[UKönig]

Sometimes the weather whips up in squalls, something that might catch a fishing boat or small coastal vessel off guard. They went out for a fishing trip and expected to be back hours earlier, but any one of a hundred reasons got in the way and slowed the return trip. The weather takes a nasty turn with tall waves and strong winds. A lot of water washing over the bow, maybe a dodgy ballast pump quits working, and before you know it, the ship turns turtle, and is lost with all hands, without a trace.
Weather related storm damage has fouled convoy operations for the escorts and merchantmen respectively and even such ocean liners as big as Queen Mary have been knocked about (so size does not always guarantee safety when out on the open seas...)
