I always launch where there's a dock...
* I back in until the transom just touches the water. (then I can stand at the winch without getting my feet wet)
* Tie the stern line to the last cleat on the dock.
* While holding the bow line, disconnect the bow tie down and winch line.
* Give the bow a slight push.
* Walk down the dock and stand at the first cleat on the dock.
* As the boat drifts by, tie the bow line to the first cleat.
* Pull in the aft line and retie it to snug the boat against the dock.
* park the car.
On retreival...
* Before backing the trailer in, pull out the winch line and attach the hook to the u-bolt mounted on top of the trailer fender.
* Back in until the last roller touches the water.
* Untile both lines - while holding the bow line, tie the end of the aft line to the dock.
* Pull the boat up to the trailer and attach the winch line (its already at the convenient spot)
* Bring the stem up so it just touches the last trailer roller.
* Crank the winch - until the boat is on the trailer.
(this may require going back and forth an extra time of 2 if the water is wavy at the time and the stem wants to jump off the
roller)
* Fasten the bow tie down.
* Untie the aft line and stow it in the boat.
* Drive off the ramp and fasten all of the other tie downs, secure the motor, etc.
