Translated in English:
MS «Silvestre» was a Norwegian-built concrete boat, built in 1919.
During the First World War, a series of smaller ships with reinforced concrete were built as building material; one of them was MS "Silvestre".
"Silvestre" was a vessel with a concrete hull, built at Fougner Staalbeton Shipbuilding Company in Moss in 1919.
"Silvestre" had several sister ships: "Namsenfjord", "Nicanor", "Carlos" and "Andres".
The ship was built for the shipping company Magnus Blikstad A / S in Hølen and from 1920 Skibs A / S Maderas in Kristiania.
The scarcity of iron and steel during the First World War was the reason why concrete was chosen as a building material.

On the way from Son to Kragerø, "Silvestre" went on the Svartskjærbåen outside Budal west of Tjøme. Since the sinking in 1925, the wreck has been a landmark in the archipelago at Tjøme.
The wreck is easily visible from Tjøme, and is a cultural monument that is not protected.
