The gyro builder du jour is Seakeeper (seakeeper.com), with an array of active-control models to fit commercial and pleasure boats as small as 30 feet. With active control, the speed and angle of gyroscopic precession (a gyro’s tendency to react to an input force at right angles to said input force) is controlled by hydraulic rams, which are, in turn, controlled by input from sophisticated sensors. Active control makes the gyro more efficient and more effective over a wider range of conditions, including very calm and very rough seas, without operator input: It’s all done by a computer. Active technology also adds expense, complexity, and maintenance, but those are trade-offs that top-notch yacht builders accept. Many now offer Seakeepers as options, and some, including MJM Yachts, include them as standard equipment. more

The Seakeeper 3 is also the only model that runs on 12-volt power rather than alternating current. It draws 900 watts on start-up, a bit less in operation, so no generator is required. Most boats will benefit from an extra battery, though. The other Seakeepers require at least 120-volt AC power, which means the genset runs whenever the Seakeeper is on duty. Most folks run the genset all the time anyway. At the dock, where Seakeeper makes partying a lot more comfortable when boat wakes roll through, shore power does the job.

Not everyone can swing a new boat, so what about retrofitting a Seakeeper? Johnstone says the gyro has to sit on “fairly substantial” structure. MJM installs stringers to accept the Seakeeper, but many boats will need additional support, adding complexity and expense to the job. Placement is also an issue: A Seakeeper is heavy—models range from 550 to almost 4,000 pounds, plus the additional weight of extra structure and ancillary gear. It doesn’t have to be mounted on the centerline from a functional standpoint, but centerline-focused weight is a factor in maintaining proper trim, said Johnstone. here

Can’t speak highly enough of it’s performance, reliability and rugged build. Absolutely changed the boat for the better. Wouldn’t use or recommend any other brand gyro.

The Tohmei Anti Rolling Gyro (ARG) is a great investment for any vessel, commercial or personal. The ARG can safely be installed inside the boat and out of the extreme conditions at sea. There are no external water hook-ups, no hi-pressure oil lines and no exposed moving parts making it safer and more reliable for everyday use. more

The Tohmei Anti Rolling Gyro stabilizer Rules the Waves with over a decade of experience creating stable situations on pleasure and commercial craft all over the world. Not only does the ARG stabilizer reduce roll at zero speed but at trolling speeds as well. The ARG does this without any high pressure hoses, hot oil or through hull fittings. In fact there is nothing that protrudes from the hull. more

The MC2X line includes nine models of stabilizers from the MC2X5 model (rpm: 4800; torque: 5.5 kNm; weight / mass: 265 kg, price around 17,500 euros) to the MC2X56 (rpm: 3500; torque: 56 kNm; weight/mass: 1400 kg; price …). The flywheel rotation system is on a horizontal axis instead of a vertical one. This is why bearings suffer less friction and maintain lower temperatures, thus not requiring water cooling. more

When the boat starts to roll, the mass does not move, it turns on itself, it reduces the roll thanks to the gyroscopic effect.
Installation on board a gyroscope always introduces greater resistance to the boat’s forward movement, not only because of the greater displacement (more weight on board, more draught), but because it is impractical to mount the gyroscope in a barycentric (longitudinal and transverse) position. As a result, the original trim of the hull is modified, tending to make it more difficult to glide and consume more fuel at the same speed. Contrary to what would be intuitively thought, instead, the stabilizing fins, thanks to their profile studied from the hydrodynamic point of view, introduce a minor increase in the resistance to forward movement (e.g. a good fin of 0.6mq resists at 20kn for 38kg V ALL). Keep in mind that in the boats of our interest the resistance given by the bow wave far exceeds the resistance introduced by wing shaped appendages (such as fins and rudders).
They have a greater ease of installation and more compact dimensions, so much so that they are interesting even for boats from eight meters in length and up.

Among gyro stabilizers, those made by Seakeeper are maybe the best known. They have a rotating part kept under vacuum to increase the rotation speed, thus reducing the necessary mass. The basic model, the Seakeeper2 (rpm: 9000; torque: 5.2 kNm; weight/mass: 188 kg, price 19 thousand euros) is suitable for 8-meter boats up to 8 tons; the biggest model, the Seakeeper 35 (rev/rpm: 5150; torque: 73 kNm; weight/mass: 1778 kg; price around 200 thousand euros), instead, is designed for yachts over 85 feet.

The size of the stabilizer should be calculated according to the anti-roll torque it delivers, ie the force with which it tends to straighten the boat. Expressed in kiloNewton meters, this means that you need a 5 kNm stabilizer for a boat of about seven tons; a 6.5 kNm stabilizer if the tons become 10 kNm and up to 130 tons of displacement if the kNm produced are 120.

Waves hit the side of a boat, and the boat rocks. It’s been as simple as that since the first Neanderthal hacked out a log canoe, and for experienced mariners it’s difficult to envision anything else happening when waves and boats interact. So when Seakeeper told us they could reduce the rocking and rolling of a boat—virtually any boat over 30’—by 70 to 90 percent, our BS detectors blew a fuse. We decided that before we wrote about how these things worked, we’d need to test them first-hand for ourselves. Here’s what happened.

[baloney]

The Seakeepers have another technical leg up on other gyro-stabilizers with their computer-controlled active control system. This constantly adjusts the attitude, or tilt, of the gyro, allowing it to provide full torque in a wide range of sea conditions.

[Cheater]

Here’s an easy way to picture the forces at work: think of a spinning top. As long as it’s spinning quickly, momentum keeps it upright and level. Since the Seakeeper is powered and it always spins at a controlled rate, that momentum is always present. [links]
