So I am hooking up with a guy in St. Augustine to have a fish replica made of my wife's Permit she caught a few years back in the lower Keys for her Birthday! He makes them out of Cyprus and his artwork is amazing! My only issue was the Permit was never measured and was out of the water maybe 30 seconds then back in! It was heavy and I would say easily over 25lbs and my only constant I have is her shoulders measure 18" wide. Any thoughts on getting an somewhat accurate measurement off this photo??
