Road.
Water.
One Vehicle.

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 ↗)

The Timing

Why Now Is the Moment

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.

01
Electric Hydrofoils Are Proven
Commercial electric hydrofoil operators like Candela have demonstrated that foil-borne EV marine craft are commercially viable, efficient, and reliable. The enabling technology stack is mature.
02
EV Components Have Matured
Battery energy density, motor controllers, lightweight composite manufacturing, and marine-grade electric propulsion have all reached the performance and cost thresholds required for a dual-medium platform.
03
Coastal Congestion Is Accelerating
Miami, San Diego, Seattle, and Nordic coastal cities face mounting traffic congestion. Waterway routes remain untapped for personal transportation. Climate-driven flooding is increasing the need for amphibious emergency response.
04
Past Amphibians Failed for Solvable Reasons
ICE inefficiency, high drag without foils, corrosion, and mechanical complexity made past amphibious vehicles impractical. Modern EV architecture and active hydrofoil technology address each of these historically fatal limitations.
The Problem

The Market Gap No One Has Solved

Transportation has remained divided between roads and waterways for over a century. The Trident LS-1 was engineered to close that divide.

Coastal Traffic Gridlock
Millions of waterfront commuters sit in traffic while navigable waterways alongside them go unused. No practical personal vehicle can switch between both.
⚓
$35B+
Boat Ownership Complexity
Recreational boat ownership requires trailers, ramps, slips, and second vehicles. The Trident LS-1 eliminates the trailer and second vehicle — garage it, drive it to the water, enter.
🏕️
600,000+
RV Owners Need a Towable Boat
RV travelers want water access without towing a separate boat trailer. The Trident LS-1 flat-tows on its own wheels behind any RV — a road and water "dinghy" in one.
🛥️
1,000+
Superyacht Tender Limitation
Existing yacht tenders cannot drive on roads to access inland areas. The Trident LS-1 extends from anchor to highway — a genuine land-sea tender.
🌊
$67B/yr
Flood Disaster Response Deficit
Flooding is the most frequent and costly U.S. natural disaster. First responders lack a vehicle that can drive to a flood zone and operate in it. Adjustable-depth foils allow shallow-water rescue.
⚡
0
Zero Practical Electric Amphibians Exist
No production amphibious vehicle today is fully electric, highway-legal, and hydrofoil-equipped. This is a category with unmet demand and a defensible first-mover position.
The Solution

Trident LS-1

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.

Trident LS-1 on hydrofoils over water

On Land —
A High-Performance EV

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 ↗)

Highway Legal Autocycle Zero Emissions / Quiet Flat-Towable — No Trailer AWD Motor-per-wheel Fits Standard Garage Adjustable Ride Height

On Water —
A Smooth-Cruising Agile Hydrofoil Boat

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. (hydrofoil flight control tech prototype we developed ↗)

Core Differentiators

Five proprietary engineering pillars create a defensible technology moat — protected by issued U.S. patent US12097733B2 ↗ with additional IP in development.

Patented
Active Stabilized Hydrofoil System
Electronically controlled hydrofoils actively adjust to sea state, providing a smooth ride and stability at speed. The system is patented and integrates with the vehicle's dual-medium control architecture — not bolted on, but designed in from the start.
80% lower drag vs displacement hulls
Patented
Dual Road-Marine Powertrain
A single integrated electric powertrain manages both road and marine propulsion. Motor-per-wheel AWD on land transitions to underwater thruster operation on water. Differential thrust provides rudderless marine steering — mechanically simpler and more reliable.
1 powertrain, 2 mediums
Engineering
HDPE Hybrid Hull Architecture
High-density polyethylene combined with an aluminum space frame delivers corrosion resistance without weight penalty — a key reason prior amphibious vehicles degraded in marine environments. Purpose-built for dual-medium durability over operational lifetime.
Engineering
Autocycle Platform + Flat-Tow Capability
Three-wheel autocycle classification provides regulatory advantages and aerodynamic efficiency on the road. The platform is uniquely engineered to be flat-towable — all four of its road operations occur with wheels on the pavement, no trailer required. No other EV does this.
Platform
Modular, Scalable Platform Architecture
The Trident LS-1 is the first vehicle in a planned product family. The modular platform architecture — shared powertrain, hull structure, and control systems — supports scaling from the recreational LS-1 to luxury, larger commercial, harbor/coast policing and search/rescue configurations. Each additional variant benefits from shared tooling and certification work. This multiplies the return on the prototype investment across multiple addressable markets.
Market Opportunity

Multiple Beachheads,
One Platform

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.
