The SeaDoo Spark is lightweight and playful! It can tow a tube with one person on it, and we include one with your rental for no extra charge. Each jet ski is equipped with a frunk (trunk in the front) for you to pack the essentials for a day on the water. With a weight capacity of 450 pounds, we recommend 1-2 riders per jet ski. While you are not responsible to return the jet ski with a full tank of fuel, the cost of fuel used will be charged to your card after it's returned.
