Seatropy

01 — The hardware

Perception built into a single enclosure.

Seatropy is three cameras and a radar unit, fused by an onboard perception model that turns raw returns into a live map of everything around your hull — the shoreline, the traffic, and the stuff that never shows up on AIS.

the enclosure — 3 cameras + radar

3 cameras, 210° of coverage: A wide-angle bow camera and a stereo pair read depth, closing speed, and shoreline in one pass — no blind spot dead ahead.
Integrated forward radar: Sees range and closing speed independent of light or line-of-sight, and keeps working when the cameras alone would struggle.
On-device fusion: Camera and radar returns are fused into a single obstacle map on the unit itself — no cloud round-trip, no signal to lose offshore.
One sealed enclosure: Rail- or mast-mountable, marine-sealed, and self-contained. One cable in, full perception out.

Two tiers

One sensor suite. Two ways to run it.

Nightsailor is the core system — full perception and obstacle detection with you at the helm. Autonomous adds self-driving and docking on top.

02 — Beyond cameras

Camera-only is yesterday's collision avoidance.

Most systems on the water are a single camera and a hope. Seatropy fuses radar with vision at the sensor level and puts real autonomy behind it.

01 — Any conditions

Sees through fog, rain, and glare

Camera-only systems go blind exactly when you need them most. Seatropy fuses radar with vision, so obstacle tracking keeps working in fog, rain, spray, and darkness — conditions that leave vision alone guessing.

02 — Small obstacles

Never misses the small stuff

Deadheads, mooring lines, kayaks, swimmers, half-submerged debris — the low, slow, easy-to-miss hazards most collision-avoidance systems are tuned to ignore. Sail without staring at the water.

03 — Autonomous tier

A real self-driving tier

Beyond alerts: switch on the autonomous tier and Seatropy holds a course, avoids traffic, and reacts to hazards on its own — an actual self-driving mode, not just a louder alarm.

04 — Docking

Docking assistance, in 3D

A live spatial view of your hull, the dock, and the closing gap between them — rendered in 3D, so close-quarters docking stops being a guess.

03 — Pricing

Buy it once. Own it outright.

Seatropy is a piece of hardware you own outright — the perception, the updates, and the obstacle detection all come with it, for as long as you have the boat.

Get early access

One-time cost

A single hardware purchase. No recurring plan, ever.

Works with zero signal

Fully on-device, so it doesn't matter if you have a connection offshore.

Updates included

Software improvements ship for the life of the hardware, at no extra cost.

Keeps working

Stop paying anyone and it still watches the water — there's nothing left to pay for.
