From my Ian Allan book of British Trawlers, 1963, it would appear that this is the original Hondo GY 668. Owned by Diamonds Steam Fishing Co Ltd, built 1961, 300 gross tons, motor trawler. Amazing, 45 years on!
Correct IMO5153981. Do not forget that the MoD had her for a while in the 80s as a target vessel - MAGPIE. At that time 2006, she was owned by Rowanwood Ltd, 48/50 Broad Street, Peterhead (Anglo Spanish principals).
