It's an expensive mistake if ya have one welded up and don't like the geometry.
This is great advice.
One question to ask when determining your frame width, is what would you like to put in your boat. If you have a cooler and dry box in mind that are a reasonable size for you boat, then build the width to fit them, since the other way around would be difficult.
To at least give you a ball park for frame width, a 66" frame seems about right to me, with the frame lengths sitting on the center of your tubes, you would have 44" between tubes for cooler and or dry box, witch is a reasonable size in a 14'. You could probably go wider, but eventually that means you start having to run longer oars, with 66", give or take a bit, that should put you in the 9-10' range.
