Williwaw was built and launched in Algonac, MI in 1958. Her hull number is 42-217. She was originally delivered to the Cooper Boat Works in St. Clair, WI. She is classified as a Constellation, Flush Deck Motor Yacht and has always been a documented vessel. She is believed to have been christened the "Miss Exide" and owned by the Exide Battery Company of Detroit. In the early 1960's she was shipped to Seattle and purchased by Tom Kipper of Kipper & Sons Engineering. She was renamed the Williwaw at that time and flew the Meydenbauer Bay Yacht Club burgee.
