Mainship's 45 Trawler is so popular that you probably can't buy one, at least not in the U.S.: A company rep told us there was only one new 45T on the market, a 2009 model at a dealership in Grasonville, MD. And that one might be gone by now. While most boatbuilders today are struggling to sell their products, Mainship's 2010 inventory of its $600,000 flagship is cleaned out. Why? What does this company have that others don't? And why won't you be able to buy a 45 Trawler next year, either?
