I sketched out a design. (Incidentally one of my more complete sketches)
So, today I got myself four 4 foot lengths of 1/2" rebar to cut up and weld into the cart.
First I welded a rectangle.
Added a cradle to hold the boat.
Added some eyes to attach tie downs to.
Then I added the forks
The finished rack. Needs paint, tires and pool noodles.
Paint going on!
