OK... Let's see if people are brave enough to tell the world the single dumbest thing you have done in boating. Can't tell on "someone else". It's what the dumbest thing YOU have done over the years. (and don't say "I bought a boat")
Here's mine:
I got my 480 DB in 2003 and was not used to not being able to see everything around when undocking like the Sundancer. My wife and kids had untied the lines but I forgot to unplug the 50 amp power cord from the power tower. Ripped the power tower right off the dock and dragged it right out of the marina before I realized what had happened. Didn't hear a thing and I'm sure it was a sight to watch as I pulled out of the marina.
