NautiSafe
Maritime Safety System
Overview
A maritime safety system for yachts and fishing boats that had to decide in real-time whether it was safe to navigate or not. The problem? You need to combine tons of data: what type of boat it is (CE safety category), how it's built (stability, hull dimensions), what the weather is like (wind, waves, forecast), and where you want to go.
I designed an algorithm that takes all this data and calculates a risk index. The boat communicates via NMEA 2000 protocols (the maritime standard for sensors and instrumentation) through Bluetooth Low Energy - low consumption and works well in marine environment with salt and humidity.
The system runs on ruggedized tablets certified for marine use. It must work even without internet (in the middle of the sea there's no signal), so I implemented offline-first architecture: nautical charts are downloaded beforehand and cached intelligently. When you return to port it syncs.
Besides safety, it handles navigation with vector maps, overlays for routes and bathymetry (sea depth), and integrates with onboard entertainment systems.
Result: system deployed on luxury yachts and commercial fishing boats, operational 24/7 even in rough seas and bad weather.
Key Features
- Navigation risk calculation combining boat type (CE category) + real-time marine weather
- NMEA 2000 protocol integration via Bluetooth Low Energy to read onboard sensors
- Works offline: cached vector nautical charts with predictive loading
- IP67 ruggedized marine-certified hardware, operational from -10°C to +50°C
