JUDICIOUS HULL #10 was weight for IRC handicap in UK using Royal Ocean Racing Clubs calibrated load cell. This weight included batteries and cushions but excluded sails and any ropes not actually attached to the rig.
The weight came out at 3285Kilogrammes which if i have done my conversions right equals 7227lbs. The boat is out of the water every winter and is not waterlogged etc.
We are competetive under IRC having won our class in Cork regatta (Ireland) a couple of years ago.
