New Zealand-born Scott Dickson and Poland's Przemek Tarnacki complete the lineup for next month's Auckland Match Racing Cup.
Three of the world's top 10 skippers are due to compete in the regatta, which is being sailed on the Waitemata Harbour from January 24-28.
The skippers include Great Britain'sIan Williams, France's Mathieu Richard, Luna Rossa helmsman James Spithill, Kiwi brothers Adam and Simon Minoprio and last year's inaugural winner, Dean Barker of Emirates Team New Zealand.
Barker will compete with the same crew - Terry Hutchinson, Don Cowie, James Dagg and Jeremy Lomas - who won last month's New Zealand match racing championships.
Royal New Zealand Yacht Squadron Commodore John Crawford said the high calibre of this year's lineup demonstrated the importance of the grade-one event, which is the last before the America's Cup.
"The high level of skippers competing shows the significance of this event on the international yachting calendar, especially as it will be a final showcase of each skipper's skills and abilities ahead of the America's Cup in Valencia," he said.
The top seed is world number two Williams who is currently leading the World Match Racing Tour. The 29-year-old is a professional sailor based in Hamble in Britain.
One place behind Williams in the world rankings is Richard, a four-time French champion in Optimist and 420 dinghies.
He also won the prestigious ISAF Nations Cup Grand Final in Ireland last year.
Eugeny Neugodnikov from Russia won the Toyota Sopot Match Race for 2006. He also came first in the Gran Premio Citta di Lugano Match Race 2005 and was third at this year's ISAF Nations Cup Grand Final in Ireland. He is ranked seventh in the world. Auckland's Simon Minoprio is ranked 16th, Barker 24th and Spithill 27th.
* It is understood BMW Oracle Racing's second new America's Cup yacht has left the boatyard in Anacortes, Seattle and is on the way to Auckland.
Unconfirmed reports say the yacht was moved from the boatyard during the night over the weekend - 24 hours after one of the town's strongest wind storms in its history.
While the syndicate is keeping tight-lipped, the new boat is expected to be shipped to Auckland from Oakland or San Francisco and arrive in two to three weeks' time.
