The following quote is from the 2016 Boaters Guide, page 27

"Waterskiing includes the towing of any person behind a vessel under
power, such as waterskiing, tubing, wakeboarding, wakesurfing, etc."

Doesn't that mean if waterskiing is not allowed, no tubing, regardless of the presence or absence of tube handles should be allowed?

see boaters guide
