It is the old rescue vessel from the North Sea which today is the houseboat and distant behind the old naval base in Copenhagen and the name was when she was in service the Vestkysten. Has never had the name H.V.Ravn, because it is a completely different ship which is being preconditioned

David, send you a picture on Clydemaritime

I don't think that this is the same ship as H V RAVN (or was there more than one?)
See http://www.axelnelson.com/skepp/ravn.htm

I think that she could be ex-ALBA II ex-GORM ex-VESTKYSTEN No.2 eX-VESTKYSTEN.
Same yard, 1944
IMO 5379236

Grateful for confirmation.

It´s a old tender ship from the DANISH MARITINE SAFETY ADMINISTRATION (FARVANDSVAESENET) Name: M/S H. V. Ravn build on Nakskov Skibsværft fra 1938-1945

She looks to be in the lines of a converted trawler
