splitditch,
Kudos building that in a season. It took me almost a season to restore a 8' pram (glass/wood). Just curious about the oars- they look a little short, specifically the loom (from the grip to the locks). I followed this formula (based upon beam not LOA surprisingly... 1/2 x beam(at the oarlocks) +2" /7 x 25 (in inches)
