Coley continued on and actually posted the fastest time of the day with a 47.109 pass, but the points went Donald's way with the second quickest run of the day.
Head was right in contention until problems with the reverse bucket in his Altherm Windows System craft. The reverse bucket allows competitors to launch craft from their trailers the only way the rules dictate.
Head's crew managed to get it working just in time, but it flew apart in the final run forcing the team out of winning contention.
The Reuben Hoeksema/Jacob Wood team guided Turbo Extreme into third spot as the only team still running in the class.
New Zealand No1 Ollie Silverton from Hamilton and his navigator Shama Putaranui won Group A with their PSP Racing machine after a series of unfortunate mishaps in rival camps.
Whanganui's Ross Travers and navigator Amanda Kittow paid dearly when they began pushing the envelop. The pair had Radioactive leading the charge early in the qualifying rounds, but pushed perhaps a bit too hard in the run-offs for the Top 3 and rolled on the first bend to put them out of contention.
Simon Gibbon from North Canterbury and Whanganui navigator Donna Thomson finished second in Novus Glass, while Sean and Fay Rice from New Plymouth wilted to third in Cosa Nostra.
New Plymouth pairing Kris Rasmussen and Holly Sutherland stepped up a notch from runners-up position in Featherston to win the Group B class at Shelterview. The class perhaps suffered the most attrition with at least three machines crashing out of contention in the countdown from Top 9 to Top 3.
At the end of the Top 3 runs, Rasmussen was leading with Waikato's Karl Beaver and Jay Ammon less then .4 seconds behind and Whanganui's Hayden Wilson and Jaedyn McDonough in third more than a second behind. In fact, Wilson was fortunate to creep into the Top 3 after an ordinary run.
However, in the final wash it was Rasmussen and Sutherland who took the full championship points with a 51.990 run ahead of Beaver in his Beaver Reliever boat and Wilson third in White Noize.
