The construction of a first boat made of steel with 50 seats is launched in 1960 in Concarneau: the Rocca I. Soon, Emile Azam realizes that it is already proving too small. Thus, in 1962, a new Vedette with 112 seats is delivered by the Chantiers de Concarneau, called Rocca 2. In 1964, Rocca is sold to finance the construction of the Rocca 3 and 4. In 1970, Emile Azam calls his 16 year old nephew sides, Eric Levavasseur. The Rocca 5 joins the fleet of existing boats. Eric asks his brother Xavier Levavasseur to join in 1977.
Attendance is steadily increasing. In 1980, the Hydraseine, a boat with 250 seats, is built by Chantiers Trait, near Rouen. This new larger boat allows evening events (150 to 200 per year). The 25m pier is too small; in 1982 the surface is doubled and hosts a bar.
