Another things to take into consideration:
- The towing vessel must have the capacity to carry everyone on board including the tubers. If you have 6 tubers, 2 observers, and an operator, your boat must have the capacity for 9 persons.
- Though it may be an extreme circumstance, if multiple people are thrown from the tubes and possiblly injured from coliding into each other, who will you rescue first or last?
- Remember the tubes you are towing are considered an extension of your boat and must follow all the navigation rules including Unsafe Passage.
