That's Bill at the wheel of his custom built Elco Express cruiser. Originally christened the Alberta B, it's 37 feet long and was powered by a 200hp Hall-Scott engine. It could hit 35mph which was very fast in the 1920's for a boat of that size. But Dodi Knapp's "Miss Demure" Sea Sled went 45 mph So out came the Hall -Scott and in went a Liberty V-12 aircraft engine which proved to be too much for the hull. I have learned that although they were good pals, Dana and Dodi always had a rivalry going on when it came to boats. The name was changed to "Wa-Hite "in 1930 after Bill and Alberta divorced. I have an unconfirmed report that Wa-Hite means "up yours" which would be understandable as there was great aniomosity between the divorced couple that followed Bill to an early grave in the New Year of 1939.
After Bill died, Ella sold the boat and it went through several hands and major neglect. Master marine mechanic, Dan Acierno of Sayville, LI. discovered it in the woods decades later and rescued it. The boat was fully restored using the original factory blueprints that Dan still has, though he no longer owns Wa-Hite . Today it is in Lake Tahoe and reportedly up for sale for close to the amount of money Bill left Ella in his will.
Dana had three Rolls Royces * , two that I have paperwork on were, a 1920 Silver Ghost chassis # 14 C.W. and a 1926 Phantom # 73 D.C. Although these are not photos of his actual cars, You can see home movies of one of his Rolls here. In the 1920's you purchased the chassis from Rolls and then had the body of your choice installed by a custom coach builder. I am sure at least one of them if not both was an open car because John LaBaire said Bill had oarlocks installed in the dashboard and door trim to hold the shotguns they used for hunting. LaBaire said that Dana and Dodi really were hard on cars back then. Plus the roads were terrible and the cars were always driven to the limits on and off them. I have copies of several repair bills from Rolls Royce of America in Garden City for Dana's actual cars. One has a $750.00 estimate to repair the chassis on the Ghost in 1927. Had to be a hell of a pot hole or was it a lopped tree he drove over?
