Model van een ijsbreker

anoniem, ca. 1750 - ca. 1807

Op deze praam is een raamwerk gemonteerd met een grote rij bijlkoppen. Door het raamwerk met touwen aan te spannen en vervolgens weer los te laten, vallen de bijlkoppen op het ijs. De rood-wit-blauw gestreepte paal is de jaagmast: met een lijn kon de ijsbreker vanaf de oever door paarden of met mankracht worden voortgetrokken.

Entry

Polychromed wooden block model of an icebreaker.

The model consists of a long pram with two wing-shaped side platforms at the rear on which capstans are placed, and a large frame balancing in a stool with an axle on the foredeck. The part of the frame overhanging the bow is weighted with a heavy wooden structure that resembles an overturned roof; a large number of axe heads have been mounted on its beams. The rear of the frame hangs above the aft deck; it can be pulled down by tugging a number of the ropes. By releasing the ropes the front section will fall and break the ice with the axe heads. This can also be done with capstans, but these were mainly used for propulsion. Alternatively the craft was towed by horses or manpower: a mast used for towing is then placed against the bulkhead of the forecastle, with a traveller running to the top. The craft has a rudder at the stern.

Jochem Pietersz Asmus (1755-1837) mentions a model of an icebreaker in his private collection in 1807.3NA 2.01.29.02 Dept. Marine, Aanhangsel I, inv. no. 20, La. E no. 24. The Amsterdam Museum has an identical model in its collection.4Amsterdam Museum, inv. no. KA 14052.
