Moody sailing yachts have been designed by Bill Dixon and by Dixon's mentor and boss Angus Primrose since forever, so there is a great deal of continuity in the design approach of Moody over the years. Unlike, say,
Oyster, who changed designers entirely a couple of times.
Bill Dixon is one of the foremost half-dozen or so yacht designers today, known especially for his one-off superyacht designs.
Dixon's teacher, Angus Primrose, was another of the great figures of yacht design, having designed the
Gypsy Moth IV and all the early Moodys. He died with his boots on, to, at the
helm of his own Moody 33 in a storm in the middle of the Atlantic.
Moodys are very common in the UK and much less so in the US. They are very strong seagoing
boats much loved by their owners, and I am not aware of any bad models. Obviously the older ones benefit less from general progress in yacht design and technology than the newer ones, but Primrose/Dixon were using
hull forms which would be considered modern today from a very early date, as early as the '80's.
Almost all of them, even the small ones, are
center cockpit designs with nice aft owners' cabins.
They are supposed to be a cut below the Swedish and Dutch boats, not to mention
Oyster and Swan, in quality but quite a bit better than what the Brits call AWB's -- Average White Boats. I am very pleased with the quality of my own Moody and have not discovered any corner-cutting anywhere.
