help

well shaped my very first board today.one thing i failed to keep in mind was my thickness in the tail for fin cups.praying there’s enough foam there.questionable for sure.what would i do just glass some on.does thickness matter then.been trying to search here through archives for close to 2 hrs. couldnt find anything.figured now a good a time as any to say hello.everyone always speaks up when they need help!this seems to be the best place for it thanks.

how thick is the tail measured from these 2 points, 3 inches up and 12 inches up? if you post we can tell you wat fin systems will fit, glassons will work with anything good luck http://www.surfboardglassing.com
