MCs FOR SALE: A general note on used MCs. The MC is the smallest and probably the strongest of all modern scows. Older MCs are still stiff, at weight, and very competitive.The MC is a very popular one design, has a large national market, a well known boat builder (Megles Boat Works), 80 fleets across the country, and many professional racers that attend major regattas with boats to sell. If you don't believe that a used MC is a good value look at how slowly the MC depreciates over time compared to other "yachts".
