I come into the windward side of that ridiculous dock with my boat bumpers on the appropriate side of the boat. Even prior to launching, I make sure that the bumpers attached to the dock pilings are adjusted properly on both sides of the dock since the wind shifts often out there. The piling bumpers are often cockeyed and have their metal buckles positioned to scrape your new boat. After landing the boat, I tie it off on both ends, back in the trailer and pull the boat far enough onto the trailer to attach the boat winch and crank it onto the trailer. That has to be the most insanely idiotic design for a boat dock in all of Christendom. Even with the above diligent preparations, your boat will seldom be unscathed when loading/unloading there.
