Over time these small shipowners began to associate with each other and specifically Alessandro Piermatteo, Vittorio Gianardi, Agostino and Luigi Rossignoli and Lorenzo Betta gave birth in December 1979 to the Navigazione Golfo dei Poeti based in Lerici, a few months later also Giuseppe Baracco himself merged into the same. In 1981 other boatmen from Portovenere Carlo, Mario and Gino Baracco, Walter Bello, Bruno Caprini, Carlo Sturlese and Giovanni Traverso also joined. At the beginning of 1982 Antonio Clerici took over the navigation from the Rossignoli brothers, as did the Navigazione Monterosso of Agostino Poggi, Angelo Poggi, Gino Moggia and Luciano Cavallo. The Navigazione Golfo dei Poeti became operational in April 1980, the founding members put their vehicles at service and began to carry out tourist services from March to October, focusing on the Spezia, Lerici, Portovenere, Islands Tour lines, the service for the Cinque Terre and going as far as Portofino once a week.
In 1976 the ATC was born, to which the province and all the municipalities of La Spezia joined, this body in a short time managed all public transport in the area and so in April 77 the aforementioned company created the IN.TUR. , a joint-stock company with public capital that managed all tourist transport in the gulf and beyond. There was thus a radical change in the services carried out by the old FI.TR.A.M and the connections were concentrated above all on the La Spezia – Lerici – Portovenere and Isola Palmaria line. The development of the other tourist lines was thus left to the emerging shipowners, because they were judged unproductive. Over the years, it focused more and more on seasonal transport with the MN Albatros I and Cormorano, but for management reasons in 1993 it was incorporated into Navigazione Golfo dei Poeti srl.
Other shipowners began to carry out tourist services at the end of the 1980s, such as the Verde Azzurro di Santerenzo company of Marco Mazzoni and Ugo Bernardi. Tommaso Baracco, son of the aforementioned Giuseppe, set up the Baracco Line, and finally the Viamare srl of Domenico Pollicardo & C.
After a few years of competition, they too merged into the Gulf of Poets Navigation, which slowly grew significantly. The Battellieri del Golfo also joined the company and shortly afterwards the service from Versilia began together with the Ligurian Tirrena by Rossignolis, thus giving life in 2000 to the Cinque Terre Golfo dei Poeti Maritime Tourist Consortium.
