01 — THE IDEA
A different way
to navigate.
SEAL is exploring an autonomous electric surface craft that uses hydrofoil lift to raise much of its hull clear of the water at speed.
The E-foil Drone brings together electric propulsion, a lightweight marine platform and autonomous navigation. The ambition is to investigate efficient, intelligent movement across water — beginning with a focused engineering demonstrator and a disciplined path from concept to validation.
↳Not a finished product. A technology direction under active study.
01 / PLATFORM STUDY
THE PLATFORM
Lift. Propulsion.
Intelligence.
Three engineering disciplines shape the EFD concept. Each must work as part of one integrated marine system.
01
Hydrofoil system
↗Submerged lifting surfaces intended to reduce hull contact with the water in foilborne operation.
02
Electric propulsion
↗A battery-electric powertrain, with propulsion and onboard electronics treated as separate systems.
03
Autonomous control
↗Navigation, sensing and active vehicle control are central research and development challenges.
02 — ENGINEERING DIRECTION
Two paths.
One objective.
SEAL is evaluating alternative foil arrangements before committing to a production architecture.
CONFIGURATION B02 / 02
FOREAFT
Four-foil arrangement
Four lifting panels with more potential for differential lift control, balanced against additional hardware and complexity.
Concept diagrams only. Final geometry, dimensions and control authority remain subject to analysis and testing.
03 — PRELIMINARY DESIGN TARGETS
Ambition,
with engineering discipline.
These figures are working design objectives for the current study — not verified specifications or demonstrated performance.

12–15kn
All values are preliminary, unvalidated design targets. Actual performance will depend on hydrodynamic testing, payload, battery selection, environmental conditions and system integration.
04 — DEVELOPMENT STATUS
From first principles
to open water.
SEAL is at the idea and early engineering study stage. The next steps are about proving the fundamentals before making performance claims.
01
CURRENT STAGE
Concept definition
Mission definition, preliminary mass and energy budgets, and foil architecture comparison.
02
NEXT
Engineering validation
Hydrodynamic modelling, structural design, propulsion matching and control-system development.
03
FUTURE
Prototype development
Build an instrumented demonstrator and validate hullborne, takeoff and foilborne operation.
04
FUTURE
Range and autonomy trials
Measure real energy use, control stability and operating limits in progressively more demanding conditions.

SEAL / FOUNDING IDEA
THE FOUNDER'S NOTE
“The opportunity is not simply to build a faster craft. It is to rethink how intelligent electric systems can operate on water.”
05 — OPEN TO EARLY CONVERSATIONS
The idea is taking
shape.
We welcome thoughtful conversations with engineers, researchers, potential collaborators and early supporters who are interested in the future of autonomous marine systems.
