Ice navigation occurs wherever a waterborne vessel transits through sea ice.One of the more common regions for ice navigation is the Baltic Sea, where vessels visiting the Baltic States will make their way through first year ice in the winter months, often with an icebreaker, or with ice reports, charts and data provided by meteorological offices.
The curved bow allows Polar Star to ride up on the ice, using the ship's weight to break the ice. [ 4 ] The 13,000-ton (13,200-metric ton) Polar Star is able to break through ice up to 21 feet (6.4 m) thick by backing and ramming, and can steam continuously through 6 feet (1.8 m) of ice at 3 knots (5.6 km/h).
The ice navigation ships are also often referred as ice-strengthened vessels. This term has no international standard and its definition may vary in different countries.
