Groninger Coasters
A painted full color artist impression of a singledeck coaster decorated the front page of our 1967 newsletter. This type of vessel became the Groninger ship par excellence from the early 1920s untill the mid-70s. The relatively small ships, with a loading capacity of 300-500 tonnes, could be built at the shipyards in the province of Groningen, where they slid sideways down from the slipway in the Winschoterdiep, Damsterdiep and Eemskanaal.
Standard ship design
Many inland shippers in those early days felt the need to leave the inland waterways and use ships for bringing and picking up freight from Germany, Denmark and Sweden. From this need, ships were designed that were seaworthy but could also deliver cargo, as it were, to the door.
Due to their shallow draught, coasters could enter all small ports. The hinterland was also accessible via canals and rivers. In short, coasters were inland vessels and seaworthy vessels in one.
Many shipyards in the Netherlands and Germany adopted the basic design of the Groninger coasters and considered it a standard. English competitors called the Groninger coasters ‘little grey devils’.
Containers appeared in the mid-70s
In the mid-70s, this type of ship was no longer needed, another type of ship was required, and containers appeared.
Most of them were scrapped, dozens were converted into sand dredgers, a few ended up in southern waters and the really lucky ones among these coasters were converted into radio broadcasting ships.
Many hundreds of Groningen coasters from that time were scrapped after spending their last years in Greek waters or in the Caribbean.
Conoship has remained active in the design of vessels for this trade throughout it’s lifetime. The size of the vessels increased, but the ideas remained the same; pragmatic and versatile vessels with low fuel consumption.
