One 2-seater SeaDoo (Spark Trixx) on a single trailer

From Flow Water Rentals

The one-of-a-kind SPARK TRIXX™ are great skis for all skill levels. Comes with the added benefits of the iBR system (Brake, Reverse, and neutral). These machines are lightweight and easy to handle. The 2-seaters are a bit less stable and easier to throw around, ride wheelies, bunny-hop, etc. Most men and High School age (or older) boys love these machines!
