According to this website https://www.shipspottersteve.com/sailing-ships.html
"She was built in 1953 at Sakuth, Heiligenhafen, Germany, a small fishing port on the Baltic Coast. It is believed Ursula was built as a cadet training ship but may have also played a part in the Cold War with sophisticated sonar and listening equipment originally installed on board.
Built to a traditional design with oak planking on oak frames, Ursula withstood the harsh Baltic conditions for many years, with lead ingots packed into the bow area for ice breaking.
After a major refit in the mid 1990's, Ursula spent 10 years operating in the Scottish Hebrides, carrying passengers on whale watching trips. During this time she was named 'Solais Na Mara' .
Overall she is 23.3m long with a 5.68m beam and 2.40m draft.
Sail area is 153m3.
Max speed 10 knots.
Gross Tonnage: 99.5 and DWT = 54.
Accommodation on board caters for 11 crew in 3 cabins, including 2 doubles.
Main Engine is a 250hp Perkins Sabre M215C.
I see she's on airbnb as well!
