America's Cup

Work to transform the viaduct is well underway, sinking piles, dredging and building breakwaters.

Auckland Council has worked with the marine industry to drastically overhaul the plan; settling on a new, visitor-friendly small 12 month navigation and safety fee for vessels over 40 metres in length.

The two remaining late challengers, Stars + Stripes USA and DutchSail, will confirm their ongoing commitment by July 1st.

Comprehensive tests to the foil arm design and construction has been led by Luna Rossa Challenge.

In updating the progress of Team New Zealand's defence campaign, Glenn Ashby revealed the exciting numbers being produced by the simulator work.

Ultimately, Ainslie expects costs to be too prohibitive for the late syndicates to join Luna Rossa, New York-based American Magic and Team UK in challenging Team New Zealand on home waters.

DutchSail joins Stars & Stripes and Malta Altus in trying to bolster the challenging fleet to six.

Kevin Shoebridge told Radio Sport that Glenn Ashby's "little x-box console" was all above the law.

"Ironically, in the last edition of the Cup in Bermuda, Team New Zealand had a mysterious device that helped the crew control foiling."

With the deadline for late entries passing on April 1, reports circulated that DutchSail, Malta Altus and Stars and Stripes Team USA had withdrawn their challenges.

A daily drain of toxins, plastics and sediments is degrading the Hauraki Gulf, a stretch of ocean from Auckland's Northland border to Waihi near Thames.

Jimmy Spithill has opened up on his decision to have another crack at the America's Cup, describing the new foiling monohull as "a praying mantis on steroids" that was irresistible.

Skipper and syndicate CEO Simeon Tienpont says the money won't be touched and will be repaid if they can't get past an April 1 deadline when they must pay part of their US$1m late entry fee.

Luna Rossa skipper Max Sirena revealed that Spithill was astonished with what was happening in front of him on the screen, declaring: "We'll s... ourselves".

Auckland Tourism, Events and Economic Development (Ateed) have estimated that a visit from just one superyacht contributes more than $1m to the economy but in many cases the return can exceed $5m.
