Update: Being naturally curious, I have spoken to both a Norwegian and a Swedish Two Star owner. Both confirmed that it is infact a Two Star 36, and it has had modifications done to the rear to make it longer.
There was a few examples of a TwoStar 38 made as well, but this is not one of them. The 38 has a rear closely resembling the 36, just two feet longer. The rest of the hull is the same (different keel, though).
At least one of the 36's has had an extension made to the rear from a design by the orginal designer of the 36/38. Others have made their own.
