A good looking "working horse" (Sorry, not proper to mention horse in maritime matters)

Hi Manuel, no she isn't the oldest one still sailing. There's Landrath Küster, built in 1889:

But I must admit that I don't know if Landrath Küster is the oldest...

Really great shot!
It might be the oldest still sailing Sietas?

Wonderful photo, Gerolf! The ship and I were born in the same year... but she looks much better at the age of 50:-)
A beautiful little ship... Sietas rocks!

Cheers,
Jens

Nice shot of this old little coaster 50years on sea
