MARINE MOTION CONTROL / SEAKEEPER + SEAKEEPER RIDE

LESS
MOTION.
MORE BOAT.

HUNTER Boatworks evaluates Seakeeper gyro stabilization on suitable non-racing vessels and Seakeeper Ride on compatible boats below the high-speed exclusion. Every installation remains hull-specific.

HUNTER STATUS / 17 OCT 2026Seakeeper’s West Coast team is engaged. An OEM gyro purchasing path has been offered; formal account setup, Ride sales terms and HUNTER installation/service authorization are still pending.
UNDERWAY MOTION CONTROL

SEAKEEPER RIDE

AT-REST + UNDERWAY ROLL CONTROL

SEAKEEPER GYROS

The current recreational gyro range spans Seakeeper 1 through Seakeeper 40. Multiple units may be used on larger vessels, but HUNTER does not infer a multiple-gyro package without factory sizing.

HUNTER BOATWORKS / STABILIZATION POLICY

RIDE WHERE IT FITS.
GYRO WHERE IT FITS.

Our default is to evaluate stabilization on suitable non-racing boats, not to force the same equipment onto every hull.

≥80 MPH CAPABLE

No Seakeeper Ride specification. High-speed performance/racing hulls stay outside HUNTER’s Ride program.

CRUISERS / FISHING / WORKBOATS / YACHTS

Evaluate gyro stabilization by hull data, displacement, usage and installation feasibility.

RIDE + GYRO

Both may be evaluated together on appropriate slower vessels, but each system is still sized and installed to its own requirements.

OLDER WOOD / FRP HULLS

Structural installation requirements are reviewed before any retrofit commitment. No generic mounting assumption.

HUNTER BOATWORKS / STABILIZATION INTAKE

START WITH
THE HULL.

Give us the boat, dimensions, hull material, displacement, engines, cruising speed and maximum speed capability. We’ll separate Ride suitability from gyro sizing rather than guessing from length alone.
