Top yachtsman Nathan Outteridge is this week embarking upon step two of a campaign to win six different world sailing titles in one year.

Outteridge, who won 49er World Titles in 2008 and 2009 started his extraordinary campaign in successful fashion last month, when he won the Moth World Championship in Belmont.

This week, Outteridge is part of a star studded crew aboard Estate Master, which is contesting the Farr 40 World Titles in Sydney.

Outteridge is sailing along side Olympic 470 World champion Malcolm Page and current World Sailer of the Year Tom Slingsby.

His pursuit of world titles will take him to Hamilton Island next month for the 505 regatta.

He then heads overseas to the SB3 Championships in England in May and the Melges 32 competition in Palmer in September, before ending the year by returning to the 49er class in Perth in December.

"I've done three or four world titles in one year before, but this is definitely going to be one of the biggest years," Outterdige told AAP on Tuesday.

"Some of them I am very well prepared for and some of them I'm in great teams and some of them the first time I'm ever going to sail the boat will be the first heat of the Worlds, so that will be interesting."

The boat to beat for the world title trophy and Rolex yacht-master watch awarded to the winners, is current world champion Nerone from Italy.

"They are certainly the favorites," Page told AAP.

Nerone, which also won the Australian Farr 40 championship last weekend, faced stiff competition from several Australian boats and the American yacht Barking Mad.

"There are 20 boats and maybe 19 can win the World Championship," Nerone tactician Vasco Vascotto told AAP.

"Barking Mad is one of the top boats, but with Transfusion, Estate Master and Kokomo, there's plenty of boats that can win."

The crews across the fleet contain numerous Olympic, America's Cup and Round the World competitors, with Australian-born America's cup winning captain James Spithill aboard American entry Goombay Smash, in his first race in his home city for the best part of a decade.

The boats will contest ten races over four days.
