GG 564 Roxen of Önnered, Sweden.

is that an ice-class bow she's got?

Yes it is as she was originally built for an owner in Finland and was used to fish/trawl in the Baltic during winter for herring.
Built in Stettin Poland in 1990 as Silva
1998 Sold to Sweden and R/N Roxen
Replaced by an bigger and more powerfull new ice strengthened Silva built by Kartensen of Skagen

Thank you for that information Nicolina. I was wondering about that bow myself, really. ;-)
