I learned the hard way on my first roller trailer with a Lund Alaskan. We were going duck hunting on Erie and i unhooked everything and put the boat on the ramp, i only missed the water by 20 feet. I can put my boat in the water fast also, i believe its because i put a boat in for duck hunting, fishing in the winter, and fishing all summer. My biggest b**ch is the guy that cant back a trailer up. If you can pull it down the road, you should be able to back it into the water the first time. If you arent sure, go to a parking lot and practice!! That would save alot of time and dirty looks your way!
