Open Boat Projects is a
platform on which water sports enthusiasts present their self-constructed DIY projects around boating. The idea for this platform was born in the german sailing forum born and brought into being by some people. It all started with a trade fair appearance at Boot 2020, where a large number of DIY projects were presented live. The aim of the whole thing is to show which tools and technical possibilities can be used to implement your own projects. The projects presented are intended to encourage interested parties to implement their own projects and to contribute their own ideas that can be used by others. The focus is on the idea of open source and open hardware as well as the exchange of ideas. In the meantime, a lot of interesting projects have been realized. More projects will be added in the future. The main exchange of ideas takes place in the sailing forum under the heading open-boat-projects.org instead of. We invite everyone interested to take part in the exchange of ideas. You don't have to be an expert to do this. Anyone who has great ideas is welcome to contribute.
In January 2026 we will again have our own Booth 11B02 from the 17.-25.01.2026 at the water sports fair Boat 2026 We will be represented in Düsseldorf. We cordially invite everyone interested to visit us at our booth. In addition to familiar projects, we will be presenting a wide range of new projects and will be available to discuss them with you. We look forward to pleasant conversations, your ideas, and inspiration for DIY projects. Information about the exhibition stand You can find more information via the link. Discounted tickets are also available on the information page. We would be grateful if you could support us with a donation for our booth.
