In an era of bow and stern thrusters on boats as small as runabouts, many skippers rely entirely on thrusters to get in and out of tough docking situations. But what if the thruster fails?

I remember the first time I climbed on board and poked around a Mainship trawler. It was an older 34-foot model, perhaps an early 80s vintage, docked in Cuba's Marina Hemingway. (Don't worry Mr. Taxman I had permission). It was tied up to the dilapidated pier and looking rather salty. The couple from Toronto had bought her for a very reasonable price and were in the middle of a one-year Great Circle cruise.
