"Øster Riisøer 3" is a cannon dinghy, or you could call it a "mini-warship". It was built in 1991 by students and is a replica of the old cannon dinghys from the early 1800s.
The boat is very treasured in Risør, and it has been a central part of the wooden boat festival for years.
It took part in the reconstruction of "Slaget ved Lyngør" (The battle of Lyngør) in 2012. This event was filmed and a TV documentary has been made about the battle in the Lyngør sound in 1812.
