Yes, you can tow a Sea-Doo in the water. There are a few things to keep in mind when doing so, however. First, make sure that the towing device you're using is rated for use with a personal watercraft (PWC). Second, be aware of your surroundings and take care not to exceed the towing capacity of your PWC or put yourself in danger by towing in rough waters. Finally, always follow the manufacturer's instructions for safe towing.
