Help Identifying 1970s Trimaran

Hi all!

I have been desperately trying (and failing) to obtain any kind of identifying information (model, builder, etc.) on the trimaran shown in the photo below.

The only info (other than the photo itself) that might be of use (according to my mother) is that my grandfather purchased the boat from someone in Miami, FL around 1972, give or take 1 or 2 years.

I also might be able to dig up/post a few more photos if they’d be helpful.

Thanks in advance (either way) for your time and help!!
Tri-ID|322x500

Maybe this may help?
