The race fleet, which is expected to attract as many as 200 entries, will start at 10am on Friday, October 21, off Devonport Wharf in Auckland, and will finish 119 nautical miles up the coast at Russell, in the Bay of Islands.
Notable frontrunners include the Orma 60 trimaran TeamVodafoneSailing, fresh back from a blitzing Australian campaign, the Cookson 50 Akatea, former winner Wired, and Roger Pagani's Triple 8 catamaran.
Last year's winners, TeamVodafone, are back for another tilt at the record after fickle winds crushed hopes of a sub-six-hour race.
At the halfway point in that event, the big red trimaran was two hours ahead of record time and looked set to beat the mark supermaxi Alfa Romeo set in 2009.
But the breeze died down and progress slowed to an agonising halt as TeamVodafone approached Cape Brett. They missed the record by nearly an hour.
Entrants will race in eight divisions, reflecting size and relative speed of each boat.
The Coastal Classic is a race designed for speed: except at the beginning and the end, there are few opportunities to overtake, and success can often depend on getting a good tactical start with clear wind and room to manoeuvre.
The race can take as little as six or seven hours for the fastest boats, or as long as two days for the slowest.
