Automatic Leveling Control

As wind shifts, water conditions change or passengers move about, the Automatic Leveling Control (ALC) will automatically adjust your trim tabs to maintain a level boat for a more comfortable and enjoyable ride.

The ALC automatically corrects the roll from side to side and pitch from fore to aft to enhance your boating experience and improve your fuel economy.

  • Microprocessor based automatic leveling trim tab control with LED tab position indicators
  • Controls roll and pitch automatically
  • Internal GPS - no GPS antenna or network required
  • Automatically adapts to varying sea conditions
  • Completely sealed and waterproof (IP68)
  • UV protected - will not deteriorate in sunlight
  • Prevents automatic corrections while turning
  • Designed for planing and semi displacement hulls larger than 20ft
  • Actuators connect directly to ALC-1 display panel (no external power module box required)
  • Automatically dims LED tab position indicators in darkness and brightens in sunlight
  • Automatically retracts trim tabs when boat is off plane or using optional key switch connection
  • Dual station operation available (ALC-1D and ALC-2D does require external power module)
  • Operates on 10 to 30 Volts DC
  • 2 Year Warranty
  • CE Approved (Compliance with EMC regulations)
