Hi Guys.....I have the correct info now.
I was wrong...it was not a "Trimaran" (my sister said she "thought" it was a Trimaran).
My uncle had my cousin call me. Here is the info:
It was the America's Cup race with Dennis Conner's 1988 Catamaran (Stars & Stripes) vs a New Zealand team. My cousin had a boat manufacturing company called RD Boatworks and they built the "boat" part of the catamaran. His speciality was catamarans, but now he is in a different area of manufacturing.
So...sorry for any confusion. (The misinformation was not my CA relatives fault...it was my families fault for not knowing what we were talking about)!
