Here is a site with a ton of info: Intercat 1500 Catamaran Forum - Index
I don't think Americat made many hulls before going bankrupt but they are very similar to the Intercat 1500 and EndeavourCat30. I have a EndeavourCat 30 in Florida. Our family loves her. We mostly day/weekend sail. She was in disarray when I bought her but a lot of elbow grease brought her up to speed. Good luck and let me know if you have any questions.
