Sorry, although similar this picture doesn’t show the SV. NIKOLAY / СВ. НИКОЛАЙ ( SV. is the short version of SVYATOY)

SV. NIKOLAY
http://www.shipspotting.com/modules/myalbum/photo.php?lid=167687

Compare both pictures and you will discover that they are two different vessels. Go to the original size pictures.

I have a picture of her name board, there it reads: СВ. НИКОЛАЙ (SVYATOY NIKOLAY).
On the name board of the acutal picture: СВт. ПЕТРа (SVYATOY PETR).

Petr means Peter but please never translate ship names, you’ll confuse those searching for a specific ship. In most cases Russian ships show a transliteration of Cyrillic names into Latin characters, it mostly is into English spelling.

Looks very like Polar Odyssey's SKT NICOLAS. Is it a later copy - or renaming?

Russian inland vessel ''Sankt petr I'''
it's from the Russian-Finnish the Polar Odyssey sailing club.

The translation from kyrillic looks like SKT. PETR(a)?
Sankt Petr ?
