i'd like to know the proper placement of the mast step on a 17 foot Otca. If someone could tell me this measurement from the inner stem of the canoe to the middle of the mast step, that would be fantastic.I just purchased an ACA sail and plan to use the canoe in sailing competitions with the ACA sailors. As you know this is a 44 sq. ft sail and my canoe is a 1922 OT Otca that has been fully restored. Serial # 69207 P.S. i restored this canoe about 4 years ago and have been using it for paddling every year. It's really a sweet ride. Thanks for your help.
