The Velux 5 Oceans website has posted a video preview ahead of the third ocean sprint stage in the marathon round-the-world yacht race.

The third stage, which kicks off tomorrow, will take the four competing yachts across the Pacific Ocean from Wellington, New Zealand to Punta de Este in Uruguay.

Sail World reports that northerly gales are expected to buffet the boats from the off as they set out on the incredible 6,000-mile route, which will take them to Nemo Point - the most remote spot in the world - and the notorious challenge of Cape Horn.

American Brad Van Liew, skipper of Le Pingouin, is currently in the lead having won the previous two ocean sprints in the 30,000-mile race.
