The women's division is again expected to be dominated by the classy St Clair pairing of Carla and Steph Laughton, who won gold in the tube rescue at the Rescue 2012 world championships in Adelaide in November, along with patient Rachel Craythorn.
There's also a serious side to the IRB racing, one perfectly demonstrated by Sunset Beach's under-21 racers Mark and Shane Edwards, who were involved in a dramatic triple rescue earlier in the summer.
The pair rescued a 41-year-old man and his two daughters, aged 14 and 11, at the Port Waikato beach, in a text-book IRB rescue.
Edwards featured heavily in the North Island IRB championships in Whakatane, which Sunset Beach won for the first time, with hours of training and rescue simulation paying off in spades during the real-life situation.
Racing begins this afternoon, with action continuing until Sunday.
