Capsize

Optimists capsize easily.

In a statement on its website, the Norwegian Coastal Administration said it feared the ship could capsize because the vessel was listing at a 40- to 50-degree angle.

Baby, I think I'm capsizing / The waves are rising and rising

But what if carrying sail capsize the boat?

There are even cases where a totally different knot may result when carelessly pulled. Tie the Granny Knot around any object and pull one end, and it will capsize into Two Half Hitches.
