SWE 181 was the second boat to be built on the original male plug for the Norlin Mk III. It was built in Gothenburg and finished in Florida on the way to WC in Sarasota 1990. This boat was later to be used as plug for the Norlin Mk III produced i Finland. Unfortunately I have very few pictures of this boat. From what I know it was sold to Australia where it hopfully still sails.
The picture below is probably from WC in Melbourne 2000 sailed by the long time owner Claes Hultling.
If you have any more info or pictures of this boat I would be happy if you get in touch.
