I raced an Equipe II XR for several years and I am not sure of it's weight but I think they were around 12-13kg. However, I have picked up a Phantom 320 and it seemed a lot heavier than the old Equipe.
I think they can make raceboards lighter, but for some reason they don't - Durability, cost?. My Equipe never had a durability issue except for the centerboard gasket.
