No.

Apparently the only boat to make it through was a tug captained by the last of the Newfoundland sealing skippers.

Oh for pities sake! Seventy years ago the USA had a dozen dedicated icebreakers that worked in the Great Lakes, New England, Alaska and Antarctica. Now we are down to a vessels pulled out of the disposal list and rebuilt originally constructed in 1976, one halfway modern Arctic class breaker commissioned in 2000, and one new small breaker in the Great Lakes to keep the waterways open on Michigan/Huron/Saint Claire and Erie and the rivers tying them together.

Meanwhile the country with an actual vision of what Ice breakers are good for has a half dozen purpose built icebreakers, several of them nuclear powered for unlimited range, and is adding a dozen or more double ended merchant ships to haul everything from liquefied fuels to bulk cargoes to containerized cargo.

The USA icebreaker capabilities at this point are almost equaled by Norway! I love Norway but the country is small with a tiny population compared to the USA with our interests on three oceans!
(Norway has 2 Icebreakers, both launched in the 21st century.)

Well, for Pete's sake, we're doing everything we can to melt the ice so we don't need ice breakers. A billion saved is a billion earned.

That was interesting, but probably they are for the Baltic shipping rather than Arctic shipping. One of the probable roots (on which Finnlines currently sails) is just north* of the island we are living on, and we occasionally see one of their ships (or one of two other passenger lines) when we have to take the small ferries between islands.


* measured in just 100s of metres/yards - the fair-lanes here can be very very narrow!

The thing to remember IMO is nce a design is built and proven using it as a model for additional units is generally cheaper than the first prototype or protype run of vessels. RO-RO ferries are a pretty common type and having a top grade ice class design for copying should be a useful event. For example the ferries that cross Lake Michigan are all very old and shut down during winter season. A ship of this new design could make the Michigan-Wisconsin run year around. Not to mention ferries to Newfoundland from Nova Scotia Canada or up the west coast from Washington to Alaska and British Columbia.
