These ten spectacular and crazy powerboat crashes will probably make you very thankful you’re not onboard.

Racing powerboats big and small crashing into one another or nose-diving... ferries on the verge of capsize. More than a few of these involve boats flying through the air, some completing a number of somersaults before landing.

There’s even some amazing footage of the crews being thrown out of the boat and dragged through the water – hopefully nobody was seriously injured.

Maybe we should've titled this one "things not to do on a boat."
