I've started to think that the dealer when the sells the boat and trailer should be giving driving and etiquette lessons to the owner. Some people just have no experiance with towing. Unfortunatly waiting until the own their own boat and are at the ramp is not the best time to learn.
I started years ago with my dad's old pick up and a small snowmobile trailer in an empty church parking lot. The smaller the trailer the harder they are to back up - small corrections go a very long way. Also keeping the trailer attached to the truck helps too, and making the boat secure to the trailer is a plus.
