Master of Errol Flynn's Yacht Zaca Captain Patrick C. Cother by Bonny J. Cother. Available on Amazon.com. $35.00. I just ordered a copy so haven't read it myself yet. Here's the description about it on Amazon:
“The words contained within the cover of this book reveal a lifestyle long ago, not known now, aboard Errol Flynn's Yacht Zaca. As Master of Zaca – Captain Patrick C. Cother was for approximately 18 months very close to Flynn. Cother and Flynn shared the love of the sea and during this extraordinary time there developed a close friendship between these two men who shared the same birthday June 20th. Although Flynn was often absent from the yacht, Cother kept in regular contact through long detailed letters of daily life on Zaca. His love of photography left a photographic historical view of life on Zaca. As a career sailor Cother kept a tidy ship and detailed log book. Little was known of this delightful time aboard the yacht, only gossip ever graced the tabloids. Flynn and Cother, my father, were Gemini men, who now we can see the twin each Gemini has. Enjoy this book you certainly will, searching for more answers to questions that will surely come to you. “
