"We are two students from the Technical University of Eindhoven and we are currently working on Protei, an open-source initiative to develop sailing drones to clean the oceans.
We designed and built a sailboat that could be easily adapted to different designs, we also took into account to built it using accessible materials and tools.
We hope that we can contribute to the Protei project by designing a platform that enables people to explore different sailboat designs and sailing principles.
We think that one of the major advantages of open-source is the ability of having a large audience during the development of the project. This is the reason why we are making an Instructable, we are hoping that you will help us in developing an autonomous oil-collecting sailing drone by contributing in one way or another. "
