An eco-responsible boat

Environmental approach

The Multimono is an environmentally friendly build designed for responsible consumers and involvement in the ECONAV network. Our wish since the design of this boat has been to lead the way to an eco-friendly build but also and above all to favour a dynamic of sharing and learning towards new cleaner and more respectful practices.

Reduced weight

An airplane wing design enables the weight of raw materials to be measurably reduced.

Kit Puzzle
