An ecological innovation
Protect your boat's hull while respecting the ocean !
Less maintenance,
more speed
We offer a simple antifouling solution: protect the hull to limit the growth of algae and barnacles. The goal is clear: keep the hull clean longer, reduce maintenance, and avoid polluting antifouling paints.
Our innovation is aimed at
boaters who want a concrete, durable, and easy-to-use protection.
It is based on an effective principle: blocking light at the hull
to prevent the development of fouling.
"Feedback after nine months of use on a First 27.7 in the Mediterranean, the glide remains perfect, and no need to clean the speedo. [...] With practice, removal takes 10 min and installation takes 10-15 min, which is very reasonable considering the biological impact and the pleasure of sailing with a clean hull."
