We consider it immpolite (and it could raise security concerns) to name or discuss the individual owner's of yachts. You can research their documentation, but the owner's name will seldom appear.
Many iterations: Starting with the Feadship hull 620 in 1979, followed by Feadship 760 in 1988. Then came the Intermarine (Savannah) #2409 in 1999 and the Palmer Johnson PJ 231 in 2000. But better known have been the Trinity series of Mia Elise yachts: 2001 T-14 Relentless (ex: Victory Lane; Mia Elise) 2002 T-17 Carpe Diem II (ex: Mia Elise; Imagine; Carpe Diem) 2003 T-26 Pipe Dreams (ex: Mia Elise; Cakewalk; Vita) 2005 T-27 Mustique (ex: Mia Elise) 2010 T-55 Mia Elise I believe for the purpose of our new member; Lise Grønskar, the question relates to the 2010 Trinity T-55. And as NYCAP writes above there is public record. In such you will find TT 164 LLC, of the Cayman Islands. That nondescript cul-de-sac is as about as far as anyone here is comfortable with. Good luck Lise... it's a heritage of beautiful yachts that share your name.
I think she was referring to this YF review: http://www.yachtforums.com/review/trinitys-180-mia-elise.4004/
