One of my secret guilty pleasures in life is a fascination with tugboats. I blame my grandfather for infecting me with the tug bug. One day while we were out on his bass boat, he pointed to a huge barge. "What do you think pushes that big, heavy barge?" he asked. No older than ten, I replied, "A humongous gigantic ship!" He laughed, and then the tug boat, dwarfed in size by the barge, came into view. This unexpected sight made quite the impression on me, I was thoroughly amazed with the tug's power. They quickly became mythologized in my mind as tireless, hard-working, under-appreciated folks of the boat world, while useless divas like yachts got all the attention.
