Who are we ?

CNG AGENCE DU PORT in Golfe-Juan, a Family story above all...

It was in 1974 that Jean Gertosio started the family nautical adventure with the Guy Couach boat brand, which he successfully marketed for 30 years.

In 1987, Pierre GERTOSIO, the second generation, imported the Italian CRANCHI brand of boats into France and then propelled this shipyard among the leaders in its category.

Based on this father-son collaboration, CNG AGENCE DU PORT became one of the main local nautical players in the Alpes-Maritimes (06). In 2010, Thomas and Olivia GERTOSIO, the 3rd generation of the family, finally joined the family business and in turn became the guarantors of the continuation of this nautical adventure.

Historic CRANCHI dealers and JOKER BOAT & STERK distributors on the French Riviera

Today, our historical CRANCHI dealer company is also JOKER BOAT distributor as well as official STERK distributor for the Alpes-Maritimes (06) and Monaco.

Implanted ideally on the Camille Rayon port between Saint Tropez & Monaco, at the gates of Cannes and Antibes, in the heart of the French Riviera yachting market, our agency benefits from a local, national and international influence.


To meet the demands of yachtsmen, we specialise in the sale of new & used boats (our core business), nautical management, maintenance (dry wintering, afloat maintenance, careening, hull service), related technical services (mechanics, electricity...) as well as boat rentals during the summer period.

Acknowledged as a nautical player, we are present at the biggest nautical events: the Cannes Yachting Festival in September, the Nautic de Paris in December and the Düsseldorf Boot in January. During these events, we unveil our ranges and new products every year.

A diversified nautical offer to meet all desires

Since 1987, we have been representing the Italian shipyard CRANCHI, a specialist in the design of exceptional motor boats. As a result, we are to this day historical dealers of the brand. The shipyard offers "Day Boat" (from 26' to 30') but also more livable Vedettes and Trawlers (from 35' to 60'). More recently, the brand has operated the launch of high-end yachts up to 78'which constitute the great novelty CRANCHI.

In order to expand our boat offer, we also became distributors of semi-rigid boats JOKER BOAT (Italian premium brand) which offers a full range of boats from 22' to 35'.

We become in 2023 STERK official dealer for France. This new German brand offers top-of-the-range open hull boats with a Mediterranean design combining comfort and performance.
