1973 O'Day Gold Medal Fleet
This advertisement was taken from a 22-page O'Day brochure in my own collection. Besides the Mariner, it provides detailed information and colored pictures of the O'Day 23 (Fixed Top and Pop Top), O'Day 22, Rhodes 19, Day Sailer II, Javelin, Widgeon, and accessories for "The Gold Medal Fleet for '73".
You can always spot a "Gold Medal Fleet" O'Day boat by the gold anodized aluminum mast and boom.
