An icebreaker is a special-purpose ship or boat designed to move and navigate through ice-covered waters, and provide safe waterways for other boats and ships. Although the term usually refers to ice-breaking ships, it may also refer to smaller vessels, such as the icebreaking boats that were once used on the canals of the United Kingdom.

The Rheinsberg Lake Region with its many great and small lakes, lies in the richly-varied, gently rolling, forested countryside between the villages of Rheinsberg, Menz and Fürstenberg/Havel in the north German state of Brandenburg. It lies just to the south of the Neustrelitz Little Lakes Region, but has no natural link to the waterbodies to the north. However, the Rheinsberg Lake Region is linked to the Neustrelitz lakes via the Wolfsbruch Canal and Lock, the Müritz-Havel Waterway and the Upper Havel Waterway. It drains southwards to the River Havel through the Rhin and is bounded by Ruppin Switzerland to the south. The overwhelming part of the region belongs to the Stechlin-Ruppiner Land Nature Park. The Stechlin Nature Reserve, created in 1938, is well known.
