The result of a dream
After several years working on cruise ships and yachts, and undertaking galley repair and maintenance projects, Yorgos Gerakis recognised the need for truly customer-oriented services in the refit, maintenance and repair of marine galleys.
In October 2012 he founded GESMAR, Gerakis Servicios Marítimos S.L.U., in Port Ginesta, Barcelona. Over the years we have earned the trust of operators, shipyards and owners as official service partner of the industry's leading galley brands, a network that grew in 2026 with RATIONAL and ambach.
