We don't build boats. We build legacies.
Every vessel is a unique collaboration — engineered with precision, crafted with passion, born from over 80 years of Italian maritime heritage.
A family of builders, shaping the sea since 1943
The Antonini legacy began in the late 1950s when founder Walter Antonini pivoted his established industrial construction business toward the naval sector — a bold move that would define three generations of shipbuilding excellence.
What started in La Spezia as a workshop repairing war-damaged metal structures has evolved into one of Italy's most respected custom superyacht builders.
