In 1947, the yacht Natoya was built by Defoe Shipbuilding Company of Bay City, Michigan for Harold DuCharme of Grosse Point, Michigan. One of five Defoe Cruise master yachts, the Natoya was 118 feet long and 18.5 feetwide. In the mid to late 1960s, the vessel was sold and migrated out of the Great Lakes to Florida. Renamed Our House III, the yacht eventually fell on hard times and was relegated for use as an artificial reef by Broward County. Renamed in memory of Wendy Rossheim, a 21-year old Fort Lauderdale resident who died of a sudden illness in December 1991, the yacht was scuttled north of Port Everglades on January 29, 1992. The Wendy Rossheim rests in 70 feet of water approximately 100 feet southwest of the Robert Edmister.
