 The law also requires all personal watercraft users to wear a life jacket as well as anyone towed on skis, tubes, boards, or other similar devices. However, state law allows an individual engaged in barefoot skiing or surfing to wear a wetsuit. A life preserver must be on board the towing vessel. And a person who is at least 16 years of age can windsurf or board sail without wearing a PFD. Water users should make sure to wear life jackets that are the appropriate size and in good condition.
