I have a good friend who has the largest jet ski and boat rental operation in St. Augustine. 20 - 25 skis on any given day.

Here are the regulations:

1. Riders must go thru a quick review of safety procedures and designated riding areas
2. Riders under 18 take a short written exam that gets then the required certification to run a watercraft
3. The rental operation must have an employee on a ski with a radio in the riding area to enforce the riding area and no wake zonesrequirements.

A bit too regulated for Jamaica?
