With registrations now closed as of October 14th, the stage is set for an adrenaline-filled showdown, as competitors and their navigators gear up to test both their skills and machinery. But there’s much more to this event than meets the eye.
A Race of Prestige and Grit
The Golden Homes New Zealand Jet Boat Marathon is one of the most prestigious events in the world of jet boat racing. It’s no surprise that every participant must be a member of Jet Boating New Zealand (JBNZ) and the New Zealand Jet Boat River Racing Association (NZJBRRA). This ensures that everyone racing is at the top of their game, with the skills and experience to take on the high demands of river racing.
Not only does this marathon promise high speeds, but it also comes with the challenge of endurance. It’s a five-day test, where racers must not only navigate the rivers but also deal with weather, river conditions, and their competitors. And to make it even tougher, there are strict rules about boat maintenance and engine changes – which we’ll get into shortly.
Four Classes, One Goal: Victory
Jet boat racing isn’t a one-size-fits-all competition, and the marathon reflects this by dividing boats into four distinct classes: A Class, Unlimited, CX Class, and FX EVO. Each class has its own set of specifications, meaning the competition is tailored for both powerful, high-performance boats and more standardized racers.
- A Class boats are restricted to a maximum engine displacement of 7700cc (or up to 9900cc for naturally aspirated engines) and a strict 750cfm carburettor limit.
- Unlimited Class boats, as the name suggests, go beyond those limits, allowing larger engines of 7701cc and beyond. This class is also home to turbine-powered monsters, offering top-tier thrills for spectators.
- The CX Class features crate engines with strict specifications, making it more about consistency and skill rather than raw power.
- Finally, the FX EVO Class is where racers can use any engine they choose, allowing for more flexibility but still under keen regulation.
This range of classes means there’s something for everyone – from boats pushing the limits of technology to those running reliable, finely-tuned engines.
Rules and Safety: Keeping it Fair and Fierce
One thing is clear: the 2024 Jet Boat Marathon isn’t just about showing up and hoping for the best. Every boat must pass a technical inspection before the race begins. This ensures that all vessels meet the strict safety and performance guidelines set out by the NZJBRRA. All boats also need to present a current Warrant of Fitness (WOF) and logbooks.
Safety is a huge priority for this marathon, with strict rules in place for what racers and their teams must wear. Life jackets are compulsory for all on board, and the colour-coded helmets – red, yellow, orange, or white – are as much for safety as they are for visibility. Every participant also has to carry a thermal blanket in a waterproof container, just in case the river conditions get a little too extreme.
The race rules don’t just stop at safety gear. The race is all about power, but it has to be self-driven. Boats must cross the finish line under their own power, without any help from outside sources like helicopters or towing. If a boat gets stuck or runs aground, a helping hand from a fellow racer or a patrol boat is allowed – but if there’s a tow involved, that boat gets hit with a “Did Not Finish” (DNF) penalty for that leg.
And speaking of penalties, racers also face stiff consequences for engine changes. If a team changes their engine during the marathon, they’ll receive a “Did Not Start” (DNS) penalty for the next leg, unless they can prove it was a catastrophic failure and get approval from race officials. Every boat’s engine will be stamped before the event to ensure no foul play.
What’s at Stake? Titles, Trophies, and Bragging Rights
It’s not just about winning a race or two. To be in contention for class titles, racers must complete at least 75% of the race legs, while the overall awards, including the prestigious 1st Piston Boat title, require teams to complete 100% of the race distance without receiving a DNS or DNF. This makes the marathon a true test of consistency, strategy, and boat reliability.
Racers know they’ll need to perform at their peak every day if they want to walk away with the top trophies. The penalties for DNS (the slowest time in class plus 30%) and DNF (the slowest time in class plus 10%) are no joke, and they keep every competitor on their toes throughout the event.
An Event Like No Other
The 2024 Golden Homes New Zealand Jet Boat Marathon promises to be an unforgettable event. With boats roaring through some of the most stunning and challenging river environments New Zealand has to offer, and the world’s best racers pushing their limits, the excitement is building. Whether you’re a seasoned jet boat racing fan or new to the sport, this is one event you won’t want to miss. So, gear up and get ready to witness high-octane thrills as the jet boaters take on Southland’s rivers in a battle for glory!
