The Trident LS-1 is the world's first highway-legal, all-electric, active hydrofoil amphibious vehicle.
It is an autocycle, recognized in most jurisdictions as a motorcycle requiring significantly less capital expenditure to obtain certification. (Ref: Certification confidence white paper ↗)
We are raising $2M to build a full-scale physical technology demonstrator prototype. (Listen to 3 minute lead founder overview ↗)
Historic amphibious vehicles failed because the enabling technologies did not exist. Modern electric propulsion, hydrofoil engineering, advanced low volume/rapid turnaround, low cost mfg technologies and lightweight fully recyclable marine HDPE hull material have changed that equation.
Transportation has remained divided between roads and waterways for over a century. The Trident LS-1 was engineered to close that divide.
A patented, highway-legal electric autocycle that transitions seamlessly from road to water — rising on active hydrofoils to cruise at 80% lower drag than a conventional boat.
The Trident LS-1 is designed from the ground up to be U.S. DOT highway compliant as a three-wheeled autocycle. Its motor-per-wheel AWD architecture delivers performance comparable to leading EVs while fitting in a standard garage — roughly the footprint of a Tesla Model X.
Its most distinctive land capability: flat-towability on its own wheels behind an RV. No trailer required. This is a unique feature in the EV industry and a major draw for the 600,000+ RV owner market.
On the water, wheels retract, hydrofoils deploy, and the vehicle rises above the surface (click for video of older v4 version demonstrating land-water-land operations ↗)
At the water's edge, wheels retract and active hydrofoils deploy — lifting the Trident LS-1 above the surface to cruise at 35+ mph with 80% less drag than a conventional displacement hull. The result is a whisper-quiet, zero-emission ride that outperforms traditional tenders in speed, efficiency, and range.
Adjustable-depth foils enable shallow-water operation with hydrofoil efficiency and smooth ride advantages where conventional hydrofoil boats cannot go.
Five proprietary engineering pillars create a defensible technology moat — protected by issued U.S. patent US12097733B2 ↗ with additional IP in development.
The Trident LS-1 serves three converging markets (amphibious vehicles, recreational boating and EVs) with a single scalable platform. The 1960s Amphicar sold nearly 4,000 units using primitive technology and their land and water capabilities are still prized today. The market has waited 60 years for a worthy successor.

Four phases from technology demonstrator to commercial production. The $2M prototype round is Phase 1 — de-risking the platform for a Series A and manufacturing partnerships.
Every dollar is tied to retiring risk and reaching a tangible, value-creating milestone. This round produces a fully functional physical demonstrator — the asset required to unlock manufacturing partnerships, pre-sales, and Series A institutional funding.
