Seakeeper 5

Vacuum-encapsulated gyroscopic anti-roll stabilizer for boats of approx. 40' - 48', with 5,000 N-m-s angular momentum at max rated speed.

Description

The Seakeeper 5 is a gyroscopic stabilizer that counteracts boat roll at rest and underway. It delivers 11% more stabilizing power than the Seakeeper 4.5 in the same footprint and spools up to stabilization in 12 minutes.

Inside a vacuum encapsulation the flywheel spins at up to 10,350 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. 40' - 48'
  • Angular momentum at max rated speed: 5,000 N-m-s
  • Spool-up time to stabilization: 12 minutes (6,210 RPM)
  • Operating power: 950 – 2,000 Watts; power input 220 VAC @ 20 Amps (50/60 Hz, Single Phase); 110 VAC @ 30 Amps (50/60 Hz)
  • Weight: 747 lbs (339 kg); envelope 26.56 L x 28.05 W x 20.98 H (inches)
  • Patented glycol/seawater cooling system and active control that adapts to sea state
  • Installed internally, with no outside appendages

Applications

  • New-build and refit installations on recreational, sportfishing and yacht hulls
