- Project started in 06/2019
- Project start as an ultrasonic distance sensor with two front sensors
- ESP8266 as an evaluation unit with WLAN
- 12V / 80mA
After some discussions in the forum, the idea came up to use a camera that is installed at spreader height and looks at the foredeck. There are already commercial products such as the CAM100 from Raymarine, but it costs around EUR 700 and can only be integrated into their plotter.… Continue reading

Official vector charts (iENCs) are available free of charge for inland waterways in Europe and the USA. Offshore charts (oeENCs) made available via o-charts.org to be acquired.… Continue reading
The database of the OpenStreetMap's database contains a lot of geoinformation, which is quite useful for planning a boat trip.
OpenNauticalChart creates a seamark-overlay from this data, OpenSeaMap makes this available online. Chart packages are also available for download, here.
A wide variety of chart styles and applications have been developed around this idea. Especially the Inland Navigator all the necessary information about bridge heights, lock times and even route planning throughout Europe is available.… Continue reading

First of all, a few important notes that you should definitely pay attention to.
The key element on board: signalk.org
SignalK is an open standard for transferring data on a boat. Interfaces for all well-known transmission protocols have since been developed around this idea:
- NMEA2000
- NMEA0183
- homebridge
- AWS IoT
- VE.Direct
- EmpirBus
- MQTT
- …
