New Technology Makes Stabilization a Reality for Boats 30’ to 50’

Seakeeper Stabalizer


Until now, owners of boats 30’ to 50’ put up with a rolling vessel in rough weather, or simply stayed ashore. With the recent launch of the state-of-the-art Seakeeper 5, they now enjoy the comfort and safety of gyro stabilization, in a wide range of sea states.

Based on the same technology found in more than 2,000 larger Seakeeper installations worldwide, the scaled Seakeeper 5 reduces resonant boat roll by up to 90% on boats 30’–50′. The unit uses a built-in computer to actively control a powerful gyro. Spinning in a vacuum environment, it produces powerful righting forces to stabilize the boat. While underway or at rest, the innovative unit dramatically lessens boat movement. And unlike traditional fins, nothing projects outside of the hull to diminish a vessel’s performance.

Builders of smaller boats are quickly recognizing the benefits Seakeeper delivers. Intrepid, MJM, Scout and several other leading brands are already offering the newly released Seakeeper 5 as standard or optional equipment.

MJM Yachts first offered Seakeeper as standard on its 50z. “MJM took an industry-leading role in making this technology standard,” said Robert Johnstone, founder of MJM Yachts. In response to strong positive feedback on the 50z, the gyro is now being offered on the company’s 40z.

“Once you know that such technology exists, you wonder why you ever put up with the discomfort of rolling before,” noted Johnstone.

Scout Boats will debut its 420 LXF with a Seakeeper 5 as an optional feature at the Miami International Boat Show. “The gyro is going to add a lot of comfort for our buyers,” said Alan Lang, Scout Boats sales manager. “It will definitely enhance the performance and overall ride of our boats.”

Only a few years ago, Seakeeper was educating consumers and builders on the merits of gyro stabilization. Now, with its newly revised line of five models, the company is bringing this innovation to the helms of small boats everywhere.

The Seakeeper 5 requires 1,500–2,000 watts to operate, depending on sea state. Weighing 790 lbs, the unit is 30″ L x 30″ W x 25″ H and can be installed off centreline. It is extremely quiet and nearly maintenance-free.

Throw away the box, this is some fresh thinking

Seemingly part sailboat and part spaceship, the new Jeanneau Yachts 55 just busted through the boundaries of traditional yacht design. I couldn’t take my eyes off the bubble hardtop that met me at the dock and I stepped aboard with trepidation. A few hours later, I was planning how to spend my not-yet-won lottery winnings.

Paving the Way to Cleaner Boating – How a Commitment to Reducing our Environmental Impact is Inspiring Cleaner Boating in Ontario

By Dave Rozycki

Over the past seven decades, Ontario’s marina industry has developed alongside some of Canada’s largest freshwater lakes. Boaters have been able to enjoy the beautiful scenery and create lasting memories on the water, with certain marinas dating back to the 1960s. As we reflect on this rich history, we can begin to see trends in how our footprint may have had an effect on the environment, in not-so-positive ways. However, by embracing innovative solutions and adopting sustainable practices, both marinas and boaters hold the key to preserving and enhancing the quality of our lakes and marine life for generations to come.
