None of those aboard were wearing flotation devices. Missouri law requires boat passengers ages 7 and younger to wear life jackets on the water, but commercial vessels are exempt. They are required only to have enough flotation devices for all passengers and crew, and life jackets that fit every child on board, said Lt. Tasha Sadowicz of the U.S. Coast Guard.
