At the coastal resorts of Florida, there are some sports that the average moviegoer in 1931 likely had never heard of. Besides outboard-motor boat racing, there are teams of woman trying to get a big balloon over the goal, tobogganing, and men punching each other until one falls into the water. He's the loser. A bit more fancifully, there's polo, with rubber floating horses and fewer drowned ponies, hitting a competing skier with sticks (called aqua-jousting) and a form of steeplechase.
What they all have in common is the racket of the outboard motors moving these people about. That noise is almost certainly why there's no narration, just title cards naming these novel sports.
