BAYWING EF-150 EXPRESS Active Fly-by-Wire Electric Hydrofoil Platform

Aero-Marine Systems is building the software-defined future of GBA maritime transit. By integrating aerospace-grade flight control algorithms with Pearl River Delta carbon-composite supply chains, the EF-150 architecture completely decouples the hull from hydrodynamic drag—slashing energy requirements by 80% and making high-speed electric commuter routes commercially viable.

2. Deep Tech Moat & Economics

Defensible OPEX Advantages

Legacy fast ferries rely on multi-megawatt diesel gas turbines pushing heavy displacement hulls. High marine fuel costs and escalating engine overhaul expenses compress operating margins. Our Fly-by-Wire control system enables a thermodynamic shift.

01. Platform Dynamics
80%

Drag Reduction

Fully submerged T-foils lift the hull completely above the waves at 18+ knots, decoupling the vessel from hydrodynamic displacement drag.

Cruise Power: ~1,100 kW
02. Core IP Moat
100Hz

Active FCS Loop

Triple-redundant Fly-by-Wire software reads IMUs and LiDAR, adjusting submerged flaps 100x/sec to neutralize Victoria Harbour wake pitch and roll.

Wake Wash: <0.15m
03. Infrastructure
4.0MWh

Shore BESS Buffer

Dockside battery storage buffers the 3.5 MW Megawatt Charging System (MCS), enabling rapid turnarounds without crashing the local municipal grid.

Charge Rate: 3.5 MW DC
04. Route Yield
78%

OPEX Savings

Direct electric pod drives yield ~$4.90 USD/NM energy costs, compared to ~$22.50 USD/NM for legacy marine gas oil turbines.

Energy OPEX: ~$4.90 USD / NM
