Seakeeper 18
Vacuum-encapsulated gyroscopic anti-roll stabilizer for boats of approx. 60' - 75', with 18,000 N-M-S angular momentum at max rated speed.
Description
The Seakeeper 18 is a gyroscopic stabilizer that counteracts boat roll at rest and underway. It is built for boats up to 56 tons, eliminates up to 95% of boat roll, and is completely internal with modest electrical power requirements.
Inside a vacuum encapsulation the flywheel spins at up to 6,150 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. 60' - 75'
- Angular momentum at max rated speed: 18,000 N-M-S
- Spool-up time to stabilization: 27 minutes (4,613 RPM)
- Operating power: 1,425 - 3,000 Watts (Sea State Dependent); power input 30 Amps @ 208 - 230 VAC, 50/60 Hz, Single Phase
- Weight: 2,460 lbs (1,116 kg); envelope 42.5 L x 43.2 W x 33.6 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
