Cutting-edge tools and know-how

Thanks to the know-how of highly qualified specialists and cutting-edge tools, CGN-Technique offers a comprehensive catalogue of maintenance services for private boats. From recreations of blueprints to repairs, not forgetting the rental of various types of equipment, CGN-Technique is a key provider of this type of service..

Unique infrastructures in the Lake Geneva region

CGN-Technique is currently transferring several boats to dry dock in order to reduce careening costs and is able to accommodate private boats (≥ 15 tons) while maintenance of its own vessels is under way.


The floating dock and dry dock have all the amenities (water, compressed air, electricity) required for standard maintenance work.

The dry dock is covered and closed. It is equipped with two overhead cranes to handle 10 tons and is ideal for all careening work.

Engineers and technicians at your service !

CGN-Technique’s engineering office uses the Autodesk Inventor CAD software. Its engineers and technicians are capable of recreating the structural, mechanical and piping blueprints of all existing boats, for the purpose of carrying out alterations or major repair work.


CGN-Technique’s engineering office uses the Proliner electronic measuring device, which makes it possible to take direct, digitalized measurements accurate to within 2 mm. The Proliner immediately and automatically generates files that can be used by a computer numerical control tool. This procedure avoids tedious measurement-taking and jig-cutting.
