Moody S31

The Bill Dixon Moody S31 was an evolution of the earlier Moody Mk I and Mk II. With her increased waterline length and greater beam, the design was Moody’s version of the popular French cruisers of a similar size. Below decks, she offers a much larger volume of accommodation than the earlier designs while being a quicker performer under sail.

Based in Largs, the Moody S31 NOKOMIS has been with her current owners for over 20 years. Frequently seen cruising the waters of the Clyde and Scotland’s west coast, she proved to be an ideal cruising yacht for a couple with occasional guests. Maintained meticulously throughout her current ownership, she is now reluctantly offered for sale as her owners prepare to retire from yacht ownership. Her extensive inventory highlights include:
