That's Manhattan in the picture-notice the statue of Liberty in the background. The Denison's where based in west michigan and Ft.Lauderdale. The Denison's were the Broward Marine people.Class V was billed as"Cost-Efficient Racing",the closest thing to pure production racing at the time.Hulls had to be 17' or longer,engines limited by c.i.d.and boats had to be available to the general public 60 days before a race.Hope this helps!
