The best, cheapest, & easiest solution:
1. go to K-mart & spend $3 dollars on a 6 foot "fun noodle" pool toy.
2. find a 12 foot cam strap.
3. cut the noodle into 2 3-ft. segments.
4. run the tail end of cam strap thru one segment, but don't run it the entire way to the cam.
5. run the same tail end either through the holes in the back of your seat or the accesory cord loops at the back of your seat, from the near side of the seat across to the other side.
6. once the strap is through your seat anchors, run the same tail end thru the second noodle segment.
7. join the tail end with the cam down at the stern grabloop of your boat, & center the the noodle segments such that they are fitted up against the back of your seat inside your cockpit.
8. adjust the strap using the cam (you want the boat to sit high so that you don't kick your stern with your achille's every step).
9. BONUS: take the rescue belt off your rescue vest & run it through the security loops on the deck of your boat. you will use this as a "sternum strap", which will pull the ass end of your boat in tight to your back.
this method freakin' works & is super cheap & the most comfortable thing i've ever tried for hiking your boat long distances. it is also cool because you don't have to really disassemble it. simply undo the cam connection & jam both noodle segments (with the strap still through them) into the stern of your boat.
