Thank you folks, but no luck. I've checked out your suggestions and cannot find who makes this vessel, its length or model year. I believe it is likely between 44' and 52' with a beam of 18' to 20'. Following the suggestions, I visited some yacht trading sites and followed their links for catamaran manufacturers. There must be at least 100! Wow, it took me a couple of days part-time to look through each. I would appreciate any new suggestions/ideas.
