Found this photo on page 72 of the February 1948 issue of Motor Boating. The caption says:
"Bogart sails, Bacall bails: one of the film colony who really sails becasue he loves it. Humphrey Bogart both headed the rules protest board and tillered Slugger to finish somewhere in the Balboa dinghy fleet. Here Bogey's wife, Betty (Laureen Bacall)(sp?), performs as a good crew should, bailing Slugger out.
I'll always appreciate the artwork you'll find on the covers of these old magazines.
TOH to Google for their continuing effort at digitizing these old magazines.
