I believe the owner of 'Seaward Fox" was working with Lars Bergstrom in Sarasota Florida. I think they had an aluminum and a carbon spar testing for the boat. Lars is no longer with us, but the company may have some info or materials. The name of the company was Bergstrom- Ridder, I think? If interested I can have my father-in-law contact them.
