You know, at first I laughed at Sean for this stupid attempt, then I began to feel guilty - he's at least trying to do something while I sit here in front of my monitor, doing nothing.
Then it dawned on me the damage he could do with this stunt. He could sink and require rescue, he could rescue someone and THEN sink, he could wander into a nest of looters and get himself and anyone with him killed, etc.
I'd forgotten the cardinal rule - know your limitations. Render assistance if you have the ability - if not, stay the h*ll out of the way.
Thankfully, it looks like Sean has reconsidered his trip and I'm back to chuckling at him.
I bet the guy who sold him the boat is still laughing.
