This means she should be:
LASS O'DOUNE (9187203), 150gt, completed Irnsum 6-1998
Her history per Miramar: 1998 AALTJE VISSER - 2009 SASHA EMIEL - 2015 LASS O'DOUNE
However, I am not convinced this is the full story!
At Esbjerg on 10 October 2011 I saw a trawler bearing the name JUPITER and fishing no. LT-34.
From what I could find on the internet subsequently she is this same vessel, and comparison of photos seems to confirm this.
Does anyone else have more specific information, please?
