Auto Leveling Control
The Automatic Leveling Control (ALC) automatically adjusts roll
from side to side and pitch from bow to stern to maintain a level
boat and more comfortable and enjoyable ride. The control may
also be operated in manual mode. This control incorporates
automatic tab retraction and calibration whenever the control
power is switched off. This unique design requires no feedback
sensor for tab position. LED indicators automatically dim at
night and brighten in sunlight. The ALC is completely sealed and
waterproof. Its rubberized cover is UV protected and will not
deteriorate in sunlight.
