Sailing technology, from sensor to cloud
We build the SWAY Breeze, its firmware, the SWAY app and the cloud behind it. All of it ourselves, in Amsterdam, and tested on our own boats.
Now we're opening that toolbox to marine brands, boatbuilders, electronics makers and race organisers. Got a product idea that lives on the boat's network? Let's build it together.
What we do
One small team that covers the whole chain: the bus on board, the box, the app in the sailor's hand and the data behind it.
NMEA 2000 & NMEA 0183
We speak the boat's language. Reading, filtering and converting NMEA 2000 to NMEA 0183, raw NMEA 2000 over TCP, and AIS. Including the proprietary messages that make autopilots move.
Embedded firmware
ESP32 firmware that runs for years below deck: logging, Wi-Fi access point, TCP and WebSocket servers, signed over-the-air updates, and a documented API for apps.
Hardware & PCB
Our own board design in KiCad, from schematic to panelised production files and assembled units. Small, low-power (0.8 W, LEN 2), made to plug straight into the boat's network.
Product development
From a sketch on a napkin to a CE-marked product in the shop: prototypes, sea trials, packaging, manuals, production and after-sales. We've done the whole route for the SWAY Breeze.
Cloud & IoT
Devices that sync themselves. Raw logs flow from the boat to the cloud and come back as trips, statistics and live positions.
Mobile, web & admin apps
One Flutter codebase for iOS, Android and web, plus the admin tools to run a fleet of devices and users.
AI & data
More than 35,000 trips and 1,000,000 nautical miles of real sailing data. We turn it into replays, leaderboards and decision support, like SteerClear AIS: collision advice that knows a sailing boat can't sail into the wind.
How we work
1. Discovery
We start on the water, or at the table. What should your product do for the sailor, which network and devices does it meet, and what does success look like? You get a clear scope and a plan.
2. Prototype
Working hardware, firmware and app screens that we test on real boats with real instruments.
3. Product
We turn the prototype into something you can sell: design, compatibility testing, documentation, app store releases and CE marking.
4. Production & support
Production files, assembly, firmware updates over the air for years, and a cloud that keeps running. We stay on board after launch.
Case study: SWAY Breeze and SWAY 3.0
The SWAY Breeze is a small Wi-Fi recorder that plugs into a boat's NMEA 2000 or Raymarine SeaTalk NG network. With the SWAY app it logs every sail and turns it into a story to replay and share. SWAY 3.0, released on 12 November 2026, helps sailors decide underway. Built in-house, end to end:
- The box: our own PCB and enclosure, CE-marked. 80 × 50 × 23 mm, 75 g, 64 GB, about two years of sailing without syncing.
- The firmware: logs the network, shares NMEA 0183 and NMEA 2000 with navigation apps over Wi-Fi, and updates itself from the app.
- Autopilot control: Raymarine and B&G autopilots from the phone, built on the pilots' own network messages and tested on real boats (beta).
- SteerClear AIS: the AIS assistant for sailors. Which vessels are closing, ahead or astern, up to 15 minutes ahead, and a wind-aware course that clears them.
- Live tracking: the boat's position for crew and family ashore, for up to 24 hours.
- The app and cloud: iOS and Android, stories, replay with a leaderboard, export, and a link with noforeignland.

What we're open to
Marine electronics makers · boatbuilders and yards · charter and fleet operators · race and rally organisers · safety and rescue organisations · sailing schools and clubs.
ODM & white label
Your brand, our proven platform. A Breeze-based device or app under your name, adapted to your boats or instruments.
Custom development
A new device, firmware for your hardware, or an app for your product. We can take on one piece or the whole chain.
Integrations & API
Connect your product or platform to SWAY sailors and their data, with the sailor's consent. Our noforeignland link is live; the Breeze already has a documented local API.
Research & collaborations
Sailing data, safety and new ways to help sailors underway. We like working with yards, universities, safety organisations and race organisers.
