In 1964, Mattel reissued The Yachtsman #789 again.  The 1964 edition included a Yachtsman's cap that was not available in the previous edition.  The stock number was changed to #0789.  This edition was only available in 1964, making it rarer than the previous edition that was available from 1962-1963.

Other editions were also reissued with the addition of a "0" in front of the original stock number.  Most editions were repeats of the original outfit, but four included variations, making them highly collectible since they were only available in 1964.

Repeated costumes (with new stock numbers) included:  #0784 Terry Togs, #0787 Tuxedo, #0788 Rally Day, #0790 Time For Tennis, #0791 Fun On Ice, #0792 Play Ball, #0793 Dr. Ken, #0794 Masquerade, #0795 Graduation, #0796 Sailor, #0797 Army and Air Force, #0798 Ski Champion and #0799 Touchdown.

Repeated costumes with variations included:  #0770 Campus Hero, #0781, Sleeper Set, #0782 Casuals and #0789 The Yachtsman.
