There is not much quite like the adrenaline rush and the freedom of being on a personal watercraft like a Jet Ski. It is important to have it insured. Costs can vary depending on the type of personal watercraft (PWC) you have. Each person’s situation is different and there are many factors that go into the cost of PWC or Jet Ski insurance. These include the year, make, model, horsepower, engine type, maximum speed, market value, after-market modifications, where and how it is stored, how you use it, and your personal claims, credit and accident history.
