Safety features to consider change based on who will be riding the towable. Small kids should use towables with cockpit seating and a low center of gravity. Wide towables, especially those with wings, are more stable than other shapes. Also consider the placement and number of handles as well as the presence of padding. Drivers who are towing the tubes should avoid going too fast or in a way that could make the tube become airborne. You should never attach more than one towable to a boat at a time.
