54-metre superyacht from Mangusta Gransport 54 range El Leon has been launched by Overmarine at their Pisa facility, in the Navicelli area. It's the first ship of the Overmarine's new fast displacement line in aluminium. These are ships that can combine long range and high performance in displacement mode with high speeds. The delivery is scheduled to the owner later this year. Overmarine first revealed the concept for the Gransport range at the 2015 Monaco Yacht Show.
