Was 107 years ago. Probably not much specific to make it an icebreaker other than a metal strip on the bow.
The sunken ship was not an icebreaker the ship that found it was.
The ship was launched on 17 December 1912 and was initially christened Polaris after the North Star. She was 144 ft (44 m) long, with a 25 ft (7.6 m) beam, and measured 348 tons gross.[2] Her original purpose was to provide luxurious accommodation for small tourist and hunting parties in the Arctic as an ice-capable steam yacht. As launched she had 10 passenger cabins, a spacious dining saloon and galley (with accommodation for two cooks), a smoking room, a darkroom to allow passengers to develop photographs, electric lighting and even a small bathroom.
Every detail of her construction had been scrupulously planned to ensure maximum durability: for example, every joint and fitting was cross-braced for maximum strength.
