I do have the Hobie heavy duty cart but they dig in really badly in the soft sand in the places that I launch when fishing the bays, I'm afraid I am putting far too much stress on the scuppers and the hull itself. I also don't like the idea of dragging it across the sand after spending so much on it I am trying to getthe most life I can out of it.
What really sucks is the tires on the Trax 2 cart wont fit on the stock cart as the trax wheels have a 1/2" arbor and the stock one is 3/4"!
