Launched my boat for the first time today. Putting it in the water was pretty easy.I backed the boat down the ramp until all the bunk boards except the front 4 inches were under water and then pulled the trailer forward and the boat slid off the trailer. When I was ready to pull the boat out of the water I backed the trailer down the ramp the same distance with the front 4 inches of the bunks out of the water. Then I started to winch the boat up to the two Y shaped bumpers in front of the winch , but the cable was dragging across the bottom bumper. This didn't seem right so I tried to pull the trailer up the ramp to let back of the boat go down (at this point it was floating). When the back of the boat went down and the front came up the boat still needed to come forward to the winch about 1 foot. I could pull it with the winch, but it seemed like was really taking a lot of force. My question is should I be backing the trailer deeper in the water and is having to pull the boat forward after pulling the trailer up the ramp normal procedure. Any insight would be appreciated.
