Some of the most horrific ocean racing stories stem around the rogue wave knock down, turtling and flipping long distance racers through a complete 360-degree spin. To ensure that the modern boats can right themselves, many of the races have a mandatory rollover test, where the boat is manually turned upside down and must prove that it can right itself.

Last week, Canadian Derek Hatfield had the test for his Open 60 ‘Spirit of Canada’ in Toronto Harbour, which he will be racing in the Vendee Globe around the world, single-handed, non stop race that starts on November 9 next year.
