Seakeeper 3

Vacuum-encapsulated gyroscopic anti-roll stabilizer for boats of approx. 35' - 41', with 3,000 N-M-S angular momentum at max rated speed.

Description

The Seakeeper 3 is a gyroscopic stabilizer that counteracts boat roll at rest and underway. It is designed to eliminate roll on boats of approximately 35-41 feet and offers a leaning post installation option for refits.

Inside a vacuum encapsulation the flywheel spins at up to 8,450 RPM. When the boat rolls, the gyro tilts fore and aft (precesses), producing gyroscopic torque to port and starboard that counteracts the roll.

Key features

  • Ideal for boats of approx. 35' - 41'
  • Angular momentum at max rated speed: 3,000 N-M-S
  • Spool-up time to stabilization: 29 minutes (6,337 RPM)
