My thoughts were that it was maybe the first name for the sceptre 20' that didn't stick. I also thought it might be an old rare model that a few were only made. It would be neat to know the story is behind it. Now that all of these scampi's have turned up it would be cool to find out that the seaquarius is even a rarer model of all the seacrafts, even more rare than the elusive 27' seavettes. Then we all can hit google earth in search for one of these birds!
