Raise the bunks

I haul my kayaks on a 5' X 8' flatbed utility trailer. I built wooden bunks that fit right into the pockets that would normally be used for side rails. Two things to consider is to make the bunks for hauling the boats on edge (always easier on the boats) and raise the bunks high enough so the boats won't drag on certain types of drive ramps etc. Another benefit of raised bunks is that it puts the overhang high enough so following vehicles can't bump the boats unless they do it with their windshield. You will have to red flag the overhang, but that isn't much of a problem. For night time driving, you might also have to rig a red light on the overhang--depending on state law. Interstate rules require a 2'x 2' red flag for overhang. My state requires only a one foot square flag.
My trailer has a 3500 lb capacity, so when I'm hauling boats, I reduce the tire pressure to around 24 psi to soften the ride.
