IGFA Rules For Butt Length of Fly Rods
Captain Fly Navarro of Fly Zone Fishing and IGFA President Jason Schratwieser cover the rules pertaining to butt length of fly rods.
Regardless of material used or number of sections, rods must conform and cast according to generally accepted fly fishing customs and practices. A rod shall not measure less than 1.82 meters (6 feet) in overall length and any rod that gives the angler an unsporting advantage will be disqualified. Overall butt length (including any extensions) may not exceed 15.24 centimeters (6 inches) when measured from the center of the reel foot to the end of the butt. Overall butt length for two-handed or spey rods longer than 3.35 meters (11 feet) may not exceed 25.4 centimeters (10 inches) when measured from the center of the reel foot to the end of the butt.
