Which of the following is NOT a type of commercial vessel?

The correct choice is personal watercraft because it is typically considered a recreational vessel rather than a commercial one. Personal watercraft, such as jet skis or similar small, powered water vehicles, are primarily used for leisure activities and personal enjoyment, not for commercial purposes or profit.

In contrast, fishing boats, freighters, and tugboats are all designed to fulfill specific commercial roles. Fishing boats are utilized for commercial fishing activities to catch and sell fish. Freighters, also known as cargo ships, transport goods and materials across bodies of water, serving a vital role in global trade. Tugboats assist in maneuvering larger vessels in harbors, on canals, and through tight spaces, playing an essential role in commercial shipping operations. Understanding these distinctions is crucial for anyone studying for a commercial boat license, as it highlights the various functions of vessels in a maritime context.
