Hydro Stix, 1970s CA surfboards

My dad owned Hydro Stix, which was a surfboard company based in San Clemente in the mid-70s. I was wondering if anyone still had any of his boards? Or remembers his company? I am trying to find enough stuff to put together some kind of gift for him (pictures, stories, etc.). Have found everything I can online already and this site was recommended.

Hello bud, my name is sean. I have a garage kept lime green hydrostix board, dated 1979 I believe. Feel free to contact me at(626) 833-9427 about it.
