BOOSTE™
Sodium-Ion Marine DC Power Architecture

Legacy lithium chemistry introduces catastrophic thermal runaway risks to unmanned engine bays and relies on critical minerals bound to Chinese supply chains. Integrated with cells from SGH's legacy Salty Marine Batteries division, BOOSTE™ represents the first 100% US-sourced, cobalt-free, and lithium-free standard for vessel repowering and defense-tech auxiliary power.

Surge-Absorbing BMS Firmware Pre-emptively buffers peak 100A+ stabilizer spin-up currents, preventing system-wide voltage sags or computer shutdowns.
Thermal-Agnostic Housing IP67 composite casing utilizing phase-change material thermal buffering. Performs continuously from -20°C to +60°C without active cooling.
Galvanically Isolated Grid Keeps high-draw payload circuits isolated from the primary navigation and command-and-control batteries.

Control Layer

Saint Troy™
Coordinated Vessel Motion Control Algorithm

Legacy vessel stabilization treats stabilizers and dynamic interceptors as isolated, uncoordinated hardware. This causes fight back (over-correction snap rolls) that damages hulls and degrades LiDAR tracking. Saint Troy™ coordinates them as one unified control loop.

Sensor-Fused Attitude Lock 100Hz real-time sensor fusion merges IMU accelerometer and gyro data to forecast wave-induced roll acceleration 500ms in advance.
Torque-to-Lift Mapping Function Preempts snap rolls by instantly matching gyroscope precession release torque with micro-adjustments to dynamic interceptor blade depth.
Sea-State Adaptive Gain Automatically shifts control profiles based on wave encounter angles (Head, Beam, Quartering, or Following seas).
Kinetic Layer

Hybrid Regen Wheels™
Kinetic Energy Recovery Systems (KERS)

Standard gyros waste significant wave-damping energy as heat. Hybrid Regen Wheels™ capture this precession torque, converting kinetic wave forces back into electricity to self-power the stabilizer and feed the propulsion grid.

Vacuum-Sealed Magnetic Bearings Flywheel assembly operating inside a <10^-5 Torr titanium alloy vacuum chamber, utilizing mag-lev bearings for zero physical contact and infinite cycles.
Variable Reluctance Generator Uses high-temperature winding coils with no permanent magnets, completely eliminating demagnetization risk inside demanding engine room climates.
Intelligent Power Routing Dynamically routes harvested wave energy to the highest-priority grid: stabilizer self-power, onboard computers, or direct electric propulsion assist.

Industrial Scale

Port Alpha Ready. Sub-Tier Integration.

Building the "Shipyard of the Future" demands high-throughput, robotic, modular vessel construction. SGH's entire advanced marine product catalog—power modules, CAN-bus control brains, and energy-recovery flywheels—is engineered as pre-assembled, drop-in, plug-and-play components to lower factory Takt times.

Pre-Assembled Footprints

All BOOSTE™ power modules and housing systems share standardized mounting patterns, fitting into modular composite bulkheads with rapid mechanical locks.

Plug-and-Play Bus Blocks

Saint Troy™ controllers utilize single-connection wiring harnesses. Pre-configured NMEA CAN networks auto-resolve node addresses on first power-up.

Simulated Digital Twins

We provide pre-compiled hardware-in-the-loop (HIL) telemetry packs, making it seamless to import SGH hardware logic into automated maritime path planning.

Investment-Grade Governance & Data Provenance

SGH operates under the absolute discipline of our **Assume Nothing** verification doctrine. Every claimed physical innovation and software capability has been reduced to running code and documented in our cryptographically sealed, tamper-proof **SGH Trade Secret Vault** (`MANIFEST.sha256`). Telemetry logs are captured using multi-node event blockchains to ensure complete provenance and chain-of-custody for all verification runs.
