CNG Agence du Port (Chantier Naval du Golfe)

CNG Agence du Port is based at Port Camille Rayon (D-Marin) in Golfe-Juan and covers the Côte d'Azur between Saint-Tropez and Monaco. The family venture began in 1974 with Jean Gertosio, continued in 1987 when Pierre Gertosio brought the Italian brand Cranchi to France, and has carried on since 2010 with the third generation, Thomas and Olivia Gertosio. The company is the long-standing Cranchi dealer and the Joker Boat and Sterk distributor for the Alpes-Maritimes.

The careening and hull service department covers hauling out, high-pressure washing, cleaning of the underwater gear (flaps, propellers, drives, thrusters) and hull shampooing with professional products. Full careening includes removing marine growth and then applying an antifouling paint presented as a premium preventive treatment, together with specific coatings for drives, IPS transmissions and sensitive areas. Replacement of zinc or aluminium anodes, blasting work and polyester repairs complete the service. Work is carried out by the company's own teams, on all types of boats.

Dry storage uses a secure storage area at the port of Golfe-Juan for boats up to 33 feet, with larger units accommodated through regional partners. It includes inspection of the hull, deck and fuel, water, gas and electrical circuits, engine maintenance with oil changes, filters and anti-corrosion protection, and a full clean of the vessel. Afloat maintenance covers checking mooring lines, fenders and covers, testing electrical and pumping systems, regular engine runs and exterior upkeep. The all-work section brings together electrics and electronics, upholstery, polyester, carpentry, metalwork and painting of hull, deck and boat components, with a single point of contact and approved specialist partners.

The agency also handles new and pre-owned boat sales, chartering and charter management, and guidance on financing, leasing and insurance. The ranges represented run from Cranchi motor boats of 26 to 78 feet to Joker Boat ribs of 22 to 35 feet, joined since 2023 by the German Sterk open boats.
