1968 O'Day Mariner Poem
This particular advertisement is from the January, 1968 edition of Yachting magazine and features Mariner #177. It also gives a rather interesting list of O'Day dealers across the U.S. as well as Bermuda and Puerto Rico.
Apparently, the O'Day Company tried to be clever by writing a poem called "The Owl and The Pussycat" to promote the Mariner's versatility.
To my knowledge, this was their first and last attempt at poetry.
