PLATFORM
Built for the Mission, Not the Brochure
WaterStrider is designed around real-world constraints — not trade show demos. Every feature exists because an operator needed it in the field.
Catamaran Hull
Stable in harbor chop and coastal currents. Dual-hull design provides a wide deck for modular payload integration and low-draft operation in shallow water.
Modular by Design
Snap-fit sections, no specialized tools. Assemble, reconfigure, or replace components in the field without engineering support.
Propulsion Agnostic
Accepts trolling motors, jet drives, or electric outboards. Match propulsion to mission — speed, endurance, or stealth.
Standardized Payload Interface
Universal mounting and power rails for sonar, cameras, SIGINT packages, or custom sensors. Swap payloads between missions in minutes.
Field Repairable
Every component is replaceable with basic tools. No depot-level maintenance required. If it breaks, fix it forward.
Multi-Vehicle Coordination
Built for swarm operations. Coordinate multiple WaterStriders for harbor surveys, perimeter patrols, or distributed sensing networks.
CONFIGURATIONS
Three Classes, One Architecture
| Class | Length | Payload | Endurance | Primary Use |
|---|---|---|---|---|
| Light | 14 ft | 610 lbs | 8 hrs | Recon, sensor deployment, expendable ops |
| Medium | 20 ft | 2100 lbs | 12 hrs | Harbor survey, multi-sensor integration |
| Heavy | 20 ft | 3390 lbs | 24 hrs | Extended patrol, towing, heavy payload |
EXPEDITIONARY DEPLOYMENT
Crate to Water in 60 Minutes
1
Transport
Ships in two standard transit cases. Fits in a truck bed, RHIB, or helicopter cargo bay. No oversized load permits required.
2
Assemble
Snap-fit hull sections, attach crossbars, mount payload rails. Two people, basic tools, 30 minutes.
3
Configure
Install mission payload, connect power and data, run self-diagnostics. Software configures automatically based on detected hardware.
4
Launch
Slide off trailer or lower from dock. GPS lock, comms check, mission start. Full autonomous or remote-controlled operation.
