Sanlorenzo S.p.a. (or Sanlorenzo) is an Italian shipbuilding company based in Ameglia, Viareggio and La Spezia, Italy.

Sanlorenzo focuses on the design and production of made-to-measure yachts and superyachts from 24 to 70 metres (79 to 230 ft) in length. According to ShowBoats International’s Global Order Book 2017, Sanlorenzo ranks as the third shipyard in the world in the construction of yachts above 24 metres (79 ft).


Foundation and development

The shipyard is established in 1958 under the name Cantieri Navali San Lorenzo Spa by Gianfranco Cecchi and Giuliano Pecchia, in the town of Limite sull’Arno, Italy.

In 1975, Giovanni Jannetti acquires the company, relocating its headquarters to the coastal town of Viareggio. Under Jannetti’s management, the shipyard gradually abandons the production of wooden vessels to focus on the development of fiberglass (GRP) yachts.

In 1985, Sanlorenzo’s first GRP model, SL57, is launched. During the following decades, the company expands into the superyacht segment, producing its first 30 metres (98 ft) long boat, SL100.

In 1999, the shipyard relocates to its actual sites in the town of Ameglia, inside a natural reserve. The shipyard is certified UNI EN ISO 14001 to guarantee that its production process respects the environment.

Under new management

In 2007, Massimo Perotti, former General Director of Azimut-Benetti through the financing of RL Investment Inc., acquires the majority of Cantieri Navali Sanlorenzo Spa by Giovanni Jannetti. The company is renamed Sanlorenzo S.p.a., and part of its production is again moved to Viareggio in 2007, where a new division for the production of larger superyachts is established in the same year.

Under Perotti’s management, the shipyard begins a period of rapid expansion, with its value of production raising from €40 mln. in 2004 to €320 mln. in 2017, investments growing from €3.39 mln. to €18.67 mln. and personnel increasing from 350 to 1,300 employees.

In 2016, Sanlorenzo establishes a third division, Sanlorenzo Superyacht, after the acquisition of a new production site in the city of La Spezia. The production of the shipyard’s entire metal superyacht line is moved from Viareggio to the new site.



Sanlorenzo’s primary production facilities are located in the town of Ameglia, in Ligury, Italy.

Built on the banks of the Magra river and inside the Montemarcello – Magra natural reserve, this shipyard became the site of the company’s headquarters in 1999, after relocation from the city of Viareggio, Tuscany.

As of 2017, the Ameglia shipyard is dedicated to the production of SL78, SL86, SD92, SL96 and SX88.

Along with the production plants, the facilities comprehend an area dedicated to after-sales services and refitting.

The site is scheduled for expansion works which, by 2018, will bring the total area of the site to 75.000 m2, including 25.000 m2 dedicated to buildings, and 2,500 m2 to the company’s offices.


The site, located in the port of the coastal town of Viareggio, in Tuscany, serves as the main production site for the largest models of the company’s

fiberglass ranges: SL106, SL118, SD112 and SD126.

Its facilities spread over a total area of 22,000 square metres (5.4 acres), with 16,000 m2 (4.0 acres) occupied by the company’s buildings. The site has direct access to the sea.

La Spezia

Sanlorenzo’s facilities in the port of La Spezia, located on the premises of the former Cantieri San Marco, extend on a total area of 50,000 square metres (12 acres), with 30,000 square metres (7.4 acres) and 1,800 square metres (0.44 acres) dedicated to production buildings and offices respectively.

The shipyard is home of the company’s new Superyacht Division, and is dedicated to the production of the whole Superyacht line.
