Common Issues (Real-World)

Based on independent service records and vessel-operator reports. These are the issues we see most frequently in the field:

AC/DC power selection confusion — installer defaults to DC without analyzing genset duty cycle
Dual-unit installations with phase-coupling errors (units fighting each other)
Stern squat compensation insufficient on planing hulls >50 ft
Shaft seal weep on long-legged vessels in following seas

            Engineering Note: Power architecture (AC vs DC), dual-unit phase synchronization, hull running attitude at cruise, and shaft seal integrity.
        

Retrofit & Integration Considerations

The crossover between recreational and light commercial. AC power is often the right choice for vessels with onboard generators, but installers avoid it due to complexity. We evaluate full genset load profile before recommending power architecture.

When Relocation Makes Sense

Commercial-to-private conversion, or vessel moving to offshore service where gyro weight penalty exceeds stabilization benefit. Dual-unit removal is a multi-day crane operation.

Power & Structural Requirements

Critical: Power and structural analysis must be completed before any installation, retrofit, or relocation. A gyro stabilizer is not a drop-in accessory — it is a high-energy rotating mass that becomes part of your vessel's structural and electrical system.

Before committing to a Seakeeper SK16 installation or service plan, we evaluate:

Real-world power draw under vessel load (not manufacturer spec)
Alternator/genset capacity at idle and cruise RPM
Battery bank chemistry, age, and capacity under load
Hull structural margin around the foundation cutout
Vibration coupling to accommodation spaces and electronics
Maintenance access for bearing service and seal replacement
