Folks,
Going from ancient memory, icebreakers go after "white ice" and not "blue ice", or ice that's extremely thick. If I remember correctly, this is to prevent the ship from riding up on the floe it can't break through and become trapped. If this happens, then pieces of the floe it's already broken through (called "bergy bits"!) can get sucked under the stern and shatter the props. Is this in fact correct?
Also, would these ships be displacement vessels, or semi-displacement vessels? And what speed would they be traveling at--six knots? Slower? Faster?
I'll be paying my good friend Mr. Google a visit in a bit, but in the meantime, if someone has some info...please share!
Thanks.
