Towing tank resistance test

By the end of last week, we managed to take the finished hull to the towing tank facilities at TU Berlin to conduct our experiments on the resistance vs. speed. The aXatlantic made her very first contact with water and also did a very good job […]

CNC milled parts!

Thanks to the chair infAR planing systems of the Bauhaus-Universität Weimar we are able to use their CNC machine for making the engine parts! Thank you so much for providing us with the machine!

Finishing the hull

During the last weeks, we managed to finish the hull to a stage where we could take it to the towing tank for the resistance test. First step was to remove the laminated hull from the mould which was quite a challenge – resulting in the […]

Vacuum laminating the hull

Here comes the exciting part of the building process: After laying four dry layers of carbon fabric on the mold, we started the timer and the mixing of epoxy resin.   All layers are throughly wet out and the wet laminate is covered in perforated film […]

Finishing the mold

After a lot of sanding and filling, the mold was ready to receive paint. More putty was used after the first paint job, to get rid of the ribs structure and the finished mold is covered in wax to make sure the hull does not […]

Smoothing the Hull

First step in the process was to trim of the excess wood at the edges using a Japanese saw and planing them flush using a small block plane.

Inserting the Keel

The keel was CNC milled in 3D and therefore just needs to be inserted into the planked hull. An opening was cut and the remaining gaps will be taken care of during the upcoming smoothing of the hull.
