Copper model of an iron buoy.
The buoy is made of plates, bolted together. It has one conical end and one spherical end. To one side it has an outlet pointing upwards. Around the spherical end a brace is fixed, with a shackle with an eye for the anchor chain; there is also an eye in the middle of the spherical end. The buoy was supposed to float with the conical end pointing upwards.
Christiaan Verveer designed this buoy as an improvement on Logan’s buoy. He was awarded a gold medal for his invention by the Provinciaal Utrechtsch Genootschap in 1833, which sent the model together with the model of Boelen’s buoy (NG-MC-838) to the Navy Model Room.
Verveer obtained a 15-year patent in 1839. He offered to sell his patent to the Department of the Navy for 5,000 Dutch guilders, but they refused. The department did buy the patent from his widow in 1845, for a tenth of the original asking price. The buoy was used as an outer buoy for the passage of Brouwershaven.
The model looks very much to be made by the same hand as model NG-MC-841, which was made by Petrus van der Loo (1806-1864).
Scale unknown.
