I've found that this isn't really much of an issue. The bunk carpeting makes it really easy to slide the sunfish along the length of the bunk. The dolly I use is homemade and pivots so the bow rests between the bunks and I can slide the sunfish onto the trailer. The dolly I made is very similar to Jim Manta's dolly except I added an additional crossbeam above the axle. I also upgraded the wheels to Harbor Freight 13" wheels since the plastic wheels tended to wobble.
