In 1837, when they were young, the brothers Meursing, Wicher and Aaldrik, had moved from Groningen to Amsterdam. Years later they managed three yards in Amsterdam: the Nachtegaal, the Concordia and a yard in Nieuwendam (Amsterdam North), where both wooden and iron ships were built.
However, they became famous for building composite ships. These ships had iron frames with a wooden skin over which copper plates were applied. These famous seven ships, all named Thorbecke (after J.R. Thorbecke, a liberal Dutch statesman), were built at the shipyard in Nieuwendam. The first in 1874 and the last in 1884. They were fast barques with a length of 55 to 60 meters. Of the first Thorbecke it is said to have completed the journey Amsterdam - Java in 71 days, equal to the first Kosmopoliet of shipbuilder Gips and the first Noach of shipbuilder Fop Smit.
The lines of Thorbecke V are totally redrawn and I compared the resistance of Windschip ‘Amsterdam’ with his forerunners.
Windschip ‘Amsterdam’ is an oceangoing sailing freighter. To load enough cargo and the need of speed are in a good balance.
In the slight V-bottom there will be enough space for tanks. The hold is separated in three decks. On the poop, you will find a small wheelhouse.
