William John Smith, 37, was last seen on the water off Port Rowan, Ontario, on the afternoon of June 23, 1983, at about 5:30 p.m. He was operating his white 31-foot 1977 Bertram hardtop cruiser with a flying bridge and twin Mercruiser 330 hp engines, hull identification number 3121641B. The boat was observed heading into the north channel toward Lake Erie and was never seen again.

William was described as a Caucasian man, 73 inches tall, 220 pounds, with blue eyes and balding short hair. He wore a dark-colored shirt, white shorts with red stripes, size 9.5 shoes, a watch, and prescription sunglasses. Despite an extensive search, neither William nor his vessel, nor any wreckage, were located.

The circumstances of his disappearance remain unclear and the case is unsolved. If anyone saw William or that Bertram on June 23, 1983, or has information about where the boat might have been, please come forward.
