I was in an 18ft. Donzi classic doing about 50 in light chop up in Puget Sound when all of a sudden right in front of me I saw floating a 4x8 sheet of 3/4 inch plywood that was made invisible by the chop until I was right on top of it. I closed my eyes and watched my life go before me (along with the engine, outdrive and transom). Turns out it was a piece of cardboard. The lower unit cut thru it clean as a razor. Good thing too because it wasn't my boat.
