The series was shot almost entirely in California so a partial mock-up of a real vessel, floating but dock bound, was used. The real vessel was used for the stock seagoing shots of the character boat "Tiki III" and it had a history. The "Pilgrim" was an eighty-five foot Alden Schooner which had sailed around the World starting in the Summer of 1932, a voyage that was chronicled in National Geographic in 1937. It was subsequently owned by several celebrities and others, including reputedly for a time Gardner McKay. In 1980 it met a sad but colorful end when it sank in the category five hurricane Allen in the Grenadines.
