The 333 differs from the earlier Mk I and Mk II Moody 33s primarily in having an aft cabin accessible from the saloon, with a double berth in place of the two singles on the 33s.
Besides the Thorneycraft, some were fitted with diesel engines by Perkins and Bukh.
Also available with single fin keel with rudder on skeg.
