go to nada click boats, and follow prompts, find your boat, it will show dry weight. this is as it came from the factory, without your add ons, and gas. if you have an outboard you can find it and it will have wt. of motor.
I have a 1992 Grady Tournament 190 (not 192 ) centerline 18'11" weight with out Engine I believe is 2075. If you go to www.gradywhite.com you can look at past year brochures with specifications. In skimming literature I think I spotted a 200-400lb swing between model years.
