Yes, just checked, 6.5. I have a 9'0 PU at 5.8kgs.
My 9'6 gun that was glassed medium heavy is about 7.4/7.5kg.
My 8'0 Gun that I'm riding in my icon photo is about 6.8kg, and that is glassed very heavy.
Sorry, but you have a heavy / bad glass job. But seriously, what else would you really expect from GSI? I'm guessing that the board was glassed and sanded by a bunch of guys working for about $7 an hour, and who have probably never surfed, although they have been taught to glass by guys who do surf... GSI...

Your choice to buy a board for a certain cheap price though. Don't mean to sound blunt and nasty... But GSI are NQR... Not Quite Right.
Open the wallet, ring up McTavish and order what you really want, and ask for a light glass job. Get a Bobsled 8'0, glassed light, with the resin squeezed out. Go for some tints, and ask for wet rub (no glass coat) to save weight.
