2021 Moomba Kaiyen w/ Trailer

Every Moomba is hand-built in Maryville, Tennessee with an industry-leading set of standards and a stable of premium options at your fingertips. Discover more about what makes the Kaiyen special below.

WAKE & SURF SYSTEMS RIDE THE WAVE

Whether you’re behind the wheel or behind the boat, our wake and surf systems are engineered to take the guesswork out of setting your boat up for big, clean wakes and waves.

Features may include:

7 inch Touchscreen

A stylish dash design with 7” touchscreen display puts even more within reach from the driver’s seat—including convenient wireless phone charging pad. The touchscreen is offset to give the driver unobstructed views and offers one-touch toggling between home, control, AutoWake® and Navigation display views.

Transom Walk-through w/ step down

Our intuitive transom walk-across with step-down makes moving between the cabin and swim deck simple, safe and smart. Not to mention easier access to that action.

Flip-up Seat Bolster & Adjustable Driver Seat

Being a captain has its rewards. Like a sturdy flip-up bolster with an optional adjustable seat to angle on all the action. In the Kaiyen worries are left dockside. Because you can’t deliver stoke unless you can see it properly.

A3 Tower

The Moomba® A3 Tower is specifically designed to add style and function. It features easy fold assist, bimini and board rack options so you can quickly grab a board when it’s time to ride and safely stow. An optional tower audio system makes the A3 tower a #1 choice.
