Moving and transporting by canoe and boat on rivers and canals is a cultural feature of the Mekong Delta and plays an important role in the economy and society. However, the management and use of equipment to support the monitoring of waterway  transport  vehicles  in  this  area  has  yet  to  receive  adequate  investment  and  attention.  Given  the  complicated evolution of the COVID-19 epidemic, it is critical to strengthen oversight of inland waterway management, as well as freight and  passenger  transportation.  This  paper  presents  the  design  and  implementation  of  an  IoT-based  support  system  for managing and monitoring passenger ships and tourism activities in smart cities. This study proposes a hybrid wireless communication  network  solution  that  takes  advantage  of  the  strengths  of  LoRa  and  Zigbee  wireless  communication technologies,  as  well  as  telecommunication  networks,  to  ensure  that  the  system  has  a  wide  operating  range  of  several kilometers, low power consumption, and can be deployed in areas where telecommunications are not available. Aside from tracking the journey and managing information about vehicles, drivers, and passengers, the system also aids in the collection of environmental parameters along river routes according to the travel route. An experimental evaluation of the system's operation was carried out for the tourist boat route between two famous tourist sites, Ninh Kieu Key and Cai Rang floating market in Can Tho city, Vietnam.
