SeaKeeper


I know everyone has succumbed to the motion in a seaway either rough condition or just a gentle roll. Seakeeper has 2 brand new products. Gyro uses a device known as a “Control Moment Gyro” and employing the magical principles of gyro dynamics, it exerts a powerful righting force that virtually eliminates boat roll, without any need for drag producing protrusions from the boat hull. Like the control moment gyros used to position spacecraft, it has a flywheel which spins in a vacuum. Stability control uses small lift producing surfaces at the stern of the boat, which rapidly extend and retract in response to the output of miniature motion sensors and processors developed by the automotive industry. These surfaces take the place of traditional trim tabs, and control running boat trim in a similar way when active control is not running.

SeaKeeper's Description

Latest press Release feb 2009

As soon as Jim McLaren, general manager of Orange Coast Yachts in Newport Beach, California, came

across the Seakeeper Gyro Stabilization System at the Fort Lauderdale International Boat Show last year, he knew he had to have it. As a result, McLaren made sure the very first 52 Ovation he ordered from Silverton Marine of Millville, New Jersey for his dealership had the state-of-the-art gyro installed.

"I felt that the Seakeeper Gyro would probably be the most important piece of equipment for boats since the invention of the autopilot and I wanted to explore it more," said McLaren. "Its, at least, the most innovative piece of equipment Ive come across in my 50 years in the marine industry."


In fact, Silverton Marine was so impressed with how the advanced Seakeeper performed on their 52 Ovation the company is now offering the unit as an option on its standard equipment list for the entire Ovation line. Supplied by Seakeeper distributor Mack Boring & Parts Company of Union, New Jersey, the revolutionary Seakeeper Model 7000 Gyro uses the principles of gyro-dynamics to exert a powerful righting force that virtually eliminates boat rock and roll.


An entirely new concept in luxury cruising, the 52 Ovation is one of the first production boats to utilize Volvos triple IPS propulsion system. A standard joystick offers one-handed maneuverability and unmatched docking capabilities. Dedicated to constant advancement in design, engineering, manufacturing and the pursuit of value, Silverton recently unveiled its Ovation 55 Sport Yacht at the Miami International Boat Show.


"During the sea trials in Delaware Bay, we used the joystick to rock the boat back and forth," said Silverton technician Rich Karrasch. "Without the gyro it was rough, but once we turned the unit on, it only took 15 seconds for the boat to completely stop rocking. We were all very impressed with how responsive it was."


A control moment gyro, the Seakeeper Model 7000 Gyro spins a forged, high-strength steel flywheel at 10,000 rpm in a near-vacuum to produce an amazing 7,000 Newton meter seconds of angular momentum or righting force. Actively controlled by motion sensors and computer processors, it optimizes torque and is highly effective over a range of conditions.


"We tested the Seakeeper Gyro just outside the entrance of Newport Harbor where there are 3ft swells," said McLaren. "The Ovation was incredibly stable, even at a complete stop. We could have sat there as long as we wanted. The boat didnt rock at all."


Designed for craft up to 60ft in length and/or 60,000 lbs. displacement, the Seakeeper Model 7000 Gyro weighs significantly less and has much lower power consumption than comparative products. Larger craft are fitted with multiple units. The compact gyro can be installed as a boat is being built or retrofitted into an existing vessel.
