Our water bike prototype launching

Here we have a short video from launching and testing of prototype of the vessel called Serenity 550 Fitness.

The main goal was to test stability and drive. Electrical support was not installed at any station yet.

As a result it was found that the water bike is very stable what means very safe against capsizing. Four adult men (of weight from 72kg up to 120kg) were standing on the one side close to the deck edge and nothing wrong was happened. We were expecting such result because this is a catamaran.

The end of November 2020.
