After the war the crew membership changed as their careers took them outside Auckland and they were replaced by a range of people over the years.

In 1949 Mitchelson was elected commodore of the RNZYS and Little Jim wore the commodore’s pennant for the 1949-1950 year. In 1951 and again in 1952 she won the RNZYS second division championship. Shortly after the war the RNZYS, given the variety of size vessels split the A class into two divisions. Little Jim was on the borderline between the divisions, but Mitchelson elected to be at the front of the second rather than at the end of the first. In 1950 with a new sail plan designed by John Brooke, Mitchelson altered her rig from a cutter to sloop with a f ractional rig.

In 1961 Mitchelson transferred ownership into his son James’s name. A major refit was undertaken in 1966 by Percy Vos which saw the removal of her cabin top and replaced with a higher and longer cabin top with a doghouse then in fashion. An engine was installed for the first time. Mitchelson noted the cost of the refit was greater than the cost of building in 1934.

 Bob Stewart redesigned and modernised her rig which resulted in a masthead rig being installed and her boom being reduced by several feet, and a larger and more powerful Genoa.
Little Jim’s long association with the Mitchelson family came to an end in 1976 with her sale to John Cronhelm, (Mitchelson, to preserve rights to a Westhaven Marina berth, held a 64th share until Cronhelm sold her to a broker several years later).

In 1982 she changed hands via a broker’s ownership to Lloyd and Linda Farrand who continued to cruise her and enter the odd race. Under their ownership she won her Anniversary Regatta race in 1987. The Farrand’s sold her in 1989 to Ron and Margaret Sharp who sailed her to their home in the Bay of Islands.
