The 28 Kingfisher I recently sold has seen 8 years of service launching on the beach at Ninilchik. It is rough on the boat and really hard on the trailer. The boat is on it's second trailer and is due for a third soon. Lower units also take a beating if the guy on the log skidder doesn't do things quite right. The captain on my boat was pretty good at hitting the trailer with no misses. We learned last summer he had no concept of pulling up to a dock. He had only run boats off the beach.
