While Commodore Sullivan owned the "Witchcraft II", he modified her to suit his sailing style and to make her easier to handle. The Harlem Yacht Club featured her on their cover in December 1939.
Frank and his love affair with "The Witch" lasted twenty-two years. Sullivan took the "Witchcraft II" on any number of weekend cruises. Frank never married and he died in 1948 five years after selling the "Witchcraft II".
