Seakeeper 10.5

The Seakeeper 10.5 marks a pivotal advancement in our quest to provide the most stabilization in the smallest, lightest, most power-efficient package. Offering 50% more gyroscopic power per cubic inch than the Seakeeper 9, it’s ideal for boats ~50-62 feet.

The next generation of Seakeeper innovations introduces the most efficient and most effective gyrostabilizers ever built.

More stabilization. Smaller Package.

Asymmetric Flywheel

An all-new flywheel design features a deeper lower hemisphere, enabling the motor to be tucked inside the flywheel. This design reduces overall height and provides the most efficient flywheel shape to maximize performance per pound and footprint.

ConnectBox Integration

The ConnectBox integrates with compatible on-board MFDs, eliminating the need to install an additional display for the Seakeeper. The ConnectBox keypad also allows the operator to control the Seakeeper directly from the unit.

Field Replaceable Bearings

Consistent with all Seakeeper models with angular momentum of 9000 NMS and greater, these new models are equipped with Field Replaceable Bearing (FRB) designs, offering greater in-field serviceability.

Single Cylinder Brake Arm

The single-cylinder brake design saves space, weight, and enhances reliability by eliminating hoses and connections. It requires no annual service and incorporates redundant safety mechanisms.

Single-Cylinder Brake

Faster Installation

The new frame can be disassembled to allow for installation in locations where it otherwise may not have fit.

Economical Maintenance

Zinc-nickel plated components, a single-cylinder brake design, and a redesigned cooling system provide better protection and easier maintenance.

Easier Access

Fewer mounting bolts, greater access clearances, and quick-release top cover fasteners make service faster and easier.
