Ultralight maybe. The minimum differential speed you're going to see with any Lakes' Freighter and a 152 with buffet in your finger tips is going to be >20kts. Basically you will have a maximum of 50' of space before you come to the end. If you are lucky the end will be off the side of the ship; if not second best will be you drop the mains between the containers. Since most stacks aren't even, this isn't likely. The most like result is that within 50' of touching your wheels you'll be stoped by a piece of steel that is a minimum of 3/8" thick, and likely of high structural integrity. With a 20+kt speed differential, not likely.
All ships are equipped with a fast rescue boat that is easy to launch, no worries, they are trained to use it. What you want to do is come from their stern quarter on the upwind side and cross his deck at wheel house level at about a 10* angle along with him heading off his leeward side. This will cause him the least course deviation to provide a lee for the rescue if the sea conditions are up. The bigger they are, the more speed you want to cross them with. A big ore carrier or container ship will take over a mile before she gets slowed down down and her boat over, so if you have the altitude to spare go ahead and take some extra speed on the way down.
