A ski accident left me with a few shoulder issues. The BoatLoader makes putting my boats up on top a non-event.
I foolishly bought two of these - one for each side. I soon found that, once a boat is on top, it can be "walked" on across to make room for the second boat.
My down-rating comes from this... Unless your bars are new or nearly new, you will have installation issues! My bars were about 4 years old and had been left outside (mounted) most of this time. There was enough corrosion inside the bar to keep the "catch" from moving. (HINT - it took a great deal of cutting to get the plastic end plug off.) I eventually got one bar to slide all right (although roughly). The second bar was too badly corroded. I did remove the plastic catch piece, and now it slides in and out. However, I must watch for the hole (which would have held the catch), then move the bar back in a few inches
Oh yeah, the sand dollar graphic on the end of the loader is great!
