AutoWake makes life easier

As the driver, you have a lot on your plate. So lets simplify it with AutoWake®. Our patented technology shines as a wakesurf and wakeboard autopilot system so you can keep your focus where it should be.

AutoWake with Multi-Sensor Technology features five patented systems working together to automatically and continuously manage the position of your hull for a precise and repeatable wake for every rider, in every water condition.

The system measures the pitch of your boat against your desired wake or wave setting and adjusts accordingly.


Too much pitch, you get a tall wave that dies quickly, too little and you have a long wave with little push. AutoWake gets it just right.


Passengers inside your boat affect the roll of the hull. AutoWake continuously measures the onboard weight distribution and adjusts ballast accordingly.

Small changes in the roll of your boat are the difference between a rampy, clean lip and a mushy wave full of whitewash. Nobody wants a mushy wave.  

AutoWake senses how deep your hull sits in the water and, relative to your desired wake or wave setting, shows you the predicted wake or wave amplitude.

The deeper the boat, the more water gets displaced. AutoWake manages variables like the number of people, ballast, fuel, and gear to automatically manage weight for you.
