Evgen>> Коллеги, мой товарищ из Уругвая ищет чертежи на такой ледокол - было что-нибудь?
Bornholmer> Glacier был в нете, шесть или восемь листов. Не оно?
@Evgen and @Bornholmer:
I think your referring to USCGC Mackinaw (WAGB-83). This is a half-sister of the "Wind Class" icebreakers, especially built to operate on the Great Lakes. These were WW2 designs. The Glacier is of a later design
More info on Wikipedia
Drawings for Mackinaw (set of 11) can be found here

Thank you for the John C Butler upload, but you shouldn't have done it, as there was already a link to that file, and the collection it's part of, here
Posting a link is quicker than downloading a file and uploading it somewhere else...... might cost you some "likes" though
