Today I learned of the 1985 Polar Sea controversy. The US Coast Guard sailed an icebreaker through the Northwest passage claiming it as international waters and sparking Canadian public outcry. One group planned to put Canadian flags in the path of the ship while another threw notes aboard asking them to leave. en.wikipedia.org/wiki/198…
In 1985, an icebreaker ship was used to save 2000 beluga wales which were trapped in a small area by a swath of ice too wide for them to cross under in one breath. The wales did not want to follow the ship through the channel until they started playing classical music over the loudspeakers. en.wikipedia.org/wiki/Mos…

There are ships called IceBreakers which go through polar or ice-covered waters.They are designed to direct the broken ice around the vehicle. The hull of an icebreaker is often a compromise between minimum ice resistance, maneuverability in ice, low hydrodynamic resistance... en.wikipedia.org/wiki/Ice…

Today I learned of double acting ships, a type of icebreaking ship designed to turn around 180Β° and proceed backwards in heavy ice conditions with the icebreaking side of the hull facing the front. In open waters, it's open water vessel bows are more hydrodynamically efficient than icebreaker bows. en.wikipedia.org/wiki/Dou…
