I did just the opposite, mrs johnr is the absolute best trailer backer at the lake. She spent about 2 hours 10 years ago backing up and down the ramp, (we were vacationing, it was a Tuesday morning, and no one was in line).
She gets me in and out of the water in literally seconds, she backs down, unhooks the front strap and safety chain when we are about a foot from the water, resumes backing down rather swiftly, the boat hits the water, I am floating back off of the trailer before I even have the motor tilted down she is pulling the truck and trailer up. She parks, and is at a mild jog heading back towards the ramp before most guys have even scratched their nuts.
This is all possible because we have a bunk trailer(so you can unhook before the boat is in the water), and we spent the time learning professional backing skills.
Everyone is envious of how easy I have it at the ramp.
God bless America...
