The ultimate high-performance SportJet 345 tender.
We've designed the SportJet 345 to fit on 16m+ yachts, so owners of mid-sized yachts can now experience the ultimate sports tender.
Its BRP Rotax engine and expertly designed sports hull give you and 4 passengers power and precision in one small but mighty package.

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 powerfulSerious 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 boardingStepping 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 backrestThe 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 limiterNew 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.
