Available Controls


The Standard Control package has a smaller footprint allowing for increased room and better access to your boat and dock. The patented design means less noise AND the fastest launch time in the industry while increasing the life of your lift’s motor. This standard control comes with each boat lift unless otherwise noted.


The HydroLaunch™ is capable of operating most brands of hydropneumatic style boat lifts which are intended to be controlled with one air valve. This control is not suited for applications that require multi-valve air control.

Push Button

The Push Button Control package uses automatic valves, eliminating the need for handles and levers. One button to lift, one to lower, and one to stop makes using your lift effortless. *OPTIONAL UPGRADE FOR UL2 LIFTS UNDER 8,800*
