One of the greatest things about ski boats and their trailers is that they are "drive on" trailers. No getting out of the boat and floating it on.

I have a "boat buddy", which means I don't even hook the winch until the boat is done with clean up and ready to drive down the road. I place the trailer to water just at the wheel wells and drive the boat on. Once I hear the click, my wife pulls us out of the water.Takes 20-30 seconds max.
