We supply a reliable and seasafe propulsion system to those who are audacious enough 

to choose wind for move


ADD Technologies

ADD Technologies created in 2018 is based in Brittany (France). We develop and commercialize AWP system (Augmented Wind Propulsion system) to decarbonize the maritime industry and provide an innovative mizzen wingsail to fishing and supply vessels.

Antoine Debled sailor and funder of the company, relying on 10 years of R&D on AWP system and with a multidisciplinary team and a network of partners, offers auxiliary and principal wind propulsion system for the existing and future fleet.





The project:

 Antoine Debled, sailor on the  Mini-Transat circuit since 1998,started try semi-rigid wingsails in 2006. It was a solution based on a 2D concept: 2 sails hoisted and spread apart; the whole being considered as a wing. Antoine Debled sailed with this solution in 2007 and ran 2500 miles but considered that, even though felt great sensations, the system could not afford  medium to strong wind conditions.

parcours Transat2In 2009 he reluctantly sails a classic softsail on the Mini Transat La Rochelle  – Salvador de Bahia. It is between the Cape Verde Islands and Brazil, where the sailors are isolated, that he find the inspiration which will give birth to the current AWP system : The easiest would be to equip a fabric sail to obtain a wing.

Since 2010, competitors and sailors have been testing AWP system on numerous sailing vessels ( windsurf, Moth foiler, sand yachting).   The innovation is now achieved and designed with manufacturing in mind. This system is protected by two patents.

With validated benefits, one of the most valuable assets is to offer low-tech development. Relying on known technologies and know-how guarantees a fast and economical installation of the propulsion system on the existing fleet.
