Gallery: F1 teams' epic Canadian GP raft race

It was another glorious edition of the traditional post-qualifying Canadian Grand Prix raft race.

Participants included all F1 teams, with the exception of a not-so-water-tight Scuderia Ferrari, a team of Formula 1 production personnel and a raft steered by a group of six lucky fans.

Everyone was given the same amount of equipment - 10 jet floats, pallets and wood, rope, paddles, life vests - and thirty minutes to build their raft.

Williams and it's Grove-tanic vessel were first to make the round-trip across the river flowed by the ship from Formula 1, with the McLaren crew frantically cruising into third.

Dramatic stuff which hopefully foreruns an equally heart-stopping race on solid ground on Sunday.
