What is outside width of your gunnels where you want the wheels?

I learned how to weld at night, but not last night. (despite how my weld looks)

My boat is a Grumman Sport Boat. It's 112 lbs., 15' 4" long, 43" wide at the widest point, 32" across the back transom, the wheels would be towards the back half of the boat, which is approximately 40" across. This would push the wheels out around 4-6" away from each side...so total width of 52" inches wide with the wheels on.

I just scientifically tested 1" square 1/8" (.120" wall)supported at two points about 60" apart and when I stepped my 240# on it I measured 3/4" deflection. Definitely would not fail, but would be a little on the springy side for my taste, which may cause undesired camber. 1" sq .120 wall is 34# for 24' while 1 1/2 sq 14ga (.083 wall) weighs 38# over 24' and would be more rigid. Even 1 1/2 16 ga (.065)wall would be fairly rigid and is 30# for 24'. In the pictures I think they have 3/4-1" sq tube. While more springy, that would not fail (as in break into multiple pieces). I think the trick will be the connection to the "d" bracket you described. If that is securely mounted to the seat and the wheel secured to it, a lot of strength will be gained. I would think making sure the toe in/out alignment of the wheels is fairly neutral would be crucial to an easy to move rig. Tack weld it all up then affix your boat to it and load the sucker down and try to roll it around your yard. Adjust as required. Post pics as you go.

Thanks for all the advice, I appreciate it. I'll be getting to work on this project in about 3 weeks when the Minnesota weather turns a little warmer.

I checked the extended forecast, PA shows snow maybe 5 days of the next 30 with this week being in the 40s 50s and 60s at some point. We've had snow on the ground for probably 5-7 days so far. It's not going to start snowing until April at this rate
