Entry
Model of an iron floating beacon, consisting of a buoy in the shape of a small boat, fitted with a mast with a screen and vane.
The buoy has a round hull with a keel. The top is closed and has a manhole and a pump, which is sealed with a hexagonal screwcap. A shackle is attached through the keel for the anchor chain. The shackle can be set in three different positions. The mast is stayed with one forestay and two backstays, which at full scale should be made of rod iron. The screen consists of three semicircles aligned between the mast and the stays. The vane has a V-shaped cutaway.
This model was made by Cornelis Jan Glavimans (1796-1857), as an improvement on the design of two models he had previously studied and tested (NG-MC-839-1, NG-MC-839-2). The third semi-circular screen was added at the suggestion of Secretary of the Navy Julius Constantijn Rijk (1787-1854) and the shape of the hull was changed according to Glavimans’ observations during the model’s trials.
Scale unknown.
