I don't have any knowledge of "Count me in" however, she may have been renamed since you sold her in 2001. there's another post on here listing some Lagoon
42's which may include your old cat: http://www.cruisersforum.com/forums/f139/tpi-lagoon-42-a-59922.html
I've also started collating information about them and will be updating a list on lagoon42.com
so it might be worth having a look and seeing if you can recognize any features from yours?
Good luck in finding your old friend!
