I came across this picture on the internet. Why do you think the owner would have done this, or was it likely unintentional? I could see if you had to do some prop work and let the boat go dry, but I would rather have the boat pulled and not risk the roll over. The boat looks like a 36' Calvin or Wayne Beal, sure is a nice looking boat with great lines. I've visited Maine's working water fronts a number of times and never seen this before.
