When I was a teen, my dad tricked me into trying to back the boat in the water by asking my to hold the brakes while he checked the plug. Everything was lined up and all I needed to do was back it straight back anouther 30yrds. Oh yea, it was 4th July weekend at the buisiest ramp in town. Well after listening to everyone yelling and cussing for 10 minutes, I shut off the truck and wandered down the river bank.
I practiced every chance I got. Started to back up and down the driveway when we would come home, later back it in off the street and into the garage. Its second nature now. At times, I still get crossed up or to close to the curb and have to stop and pull forward. That usually happens when Im in a hurry.
When I launch, I have a 30' dock line attatched to the bow and clipped to the trailer. I back in till the boat floats, pull forward slowly till I can walk between the trailer and water line. Unclip the boat and push to the shore.
When loading, I slide on my knee high rubber boats and wade at the back bumper and drag the boat on the trailer. It works real good when Im by myself. If someone else is along, I just let them hold the dockline.
