Model of an Icebreaker

anonymous, c. 1750 - c. 1807

A frame with a large row of axe-heads has been mounted on this flat-bottomed boat. Ropes are used to raise, then release the frame, causing the axe-heads to fall on the ice. The red, white and blue striped pole is the towing mast: a line attached to it enabled the icebreaker to be towed from the bank by horses or men.

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.
