I know of someone who was launching at S.P. There was no wind, very calm. They went to launch their boat and said " I can push it in slowly and run up on the dock and tie it up. Well the boat was faster than he was, honest there was a slight gust of east wind . The boat was adrift in the middle of the harbor. He then asked another boat "I can you push mu boat back to the dock? " That brave sole tried to push it bachelor
He had a 17 ft aluminum boat yo push a 24 ft fiberglass boat. I watched him bounce off the fiberglass boat. Finally after numerous tries both boats were at the slip. I'll never admit to that. But from now on I always have s line attached._
