We’ve designed the SportJet 520 to fit on 30m+ yachts. Utilising the ultra-reliable 230hp Rotax engine, the Sportjet 520 can achieve a blistering top speed of 56mph, so you wont be able to wipe the smile from your face.
The SportJet 520, our largest model in the SportJet lineup, offers a spacious sunbathing area, ample storage, and the capacity to accommodate seven adults comfortably.
From practical tender duties to adrenaline-fuelled days in the sun, the SportJet 520 is the master of them all.
SportJet 520 in Action
More space, more practicality.
The SportJet is filled with features to help you play and relax on the sea.
A large aft platform gets you and your gear in and out of the water with ease. A removable ski pole turns your boat into a wakeboarder’s dream, and clever helm seat hinges create a sunbathing spot to soak up the rays.
Performance meets safety.
The SportJet’s pinpoint handling and blistering acceleration makes it irresistible.
Its ultra-responsive jet propulsion system lets you manoeuvre confidently at low speeds. And with no exposed moving parts, you can swim and dive from the boat without worry
Seriously powerful
Serious power at your command.
Extreme sports need extreme torque - and the SportJet delivers in spades. Just flick the throttle and tell your water skier to hold on.
Easy boarding
Stepping aboard couldn’t be easier.
With the option of a 1.2m tall boarding pole and sturdy step pad, stepping on and off your tender couldn’t be easier - so you’ll only be swimming in the sea when you want to be.
Automatic bow inflation option.
The SportJet’s bow deflates to fit the tightest of garages.
And when you’re ready to set sail again, inflate the bow with the flick of a switch and you’ll be hitting the open water in a matter of minutes.
Rotating backrest
The SportJet might feel like a race car on water, but it’s just as focused on keeping you comfortable.
That’s why we created a rotating backrest, giving you extra space for rear-facing passengers and increasing the size of the sunpad when at anchor.
Power limiter
New to high-performance tenders? Learn in a safe environment.
The SportJet’s power limit switch means those new to the world of high-performance tenders can learn in a safe environment - until they’re ready to throw off the learner plates and really put the hammer down.
Flip-up footrest
Because comfort for passengers is everything.
We designed the SportJet with an aft footrest, so you can comfortably stay put even as the SportJet takes off.
