why does my shortboard seem so heavy?

I just made a 6’4" thruster. It weights about 10 lb. What is the typical weight for this board? Should I sand more hot coat off? Thanks alot Nick

Did you use 6oz glass instead of 4oz? You can sand down to where you start to see slight weave to remove excess resin then coat with acrylic to hide weave…

…my bet is…your lam went off slowly and the blank saturated loads of resin. …Typical wt.s of a board your size are between 4-7 lbs.Herb
