Final answer:
In Virginia, all human-powered vessels are exempt from titling and registration, while motorboats, sailboats, and powerboats typically require it.
Step-by-step explanation:
The vessels that are exempt from being titled and registered in Virginia are all human-powered vessels. In Virginia, motorboats, sailboats, and powerboats generally require titling and registration due to their use of motors or sails for propulsion. However, vessels propelled solely by human power, such as canoes, kayaks, and rowboats, do not need to be titled or registered.
