Who is legally allowed to operate a vessel with more than 25 horsepower?

The correct choice highlights the specific regulation regarding the operation of vessels with more than 25 horsepower. In New Hampshire, individuals under the age of 16 may operate such vessels, but they must be accompanied by an adult who possesses the proper boating safety education certification. This rule is in place to ensure that younger operators have adult supervision while gaining the skills and knowledge required for safe boating.

This approach balances safety concerns with the desire to allow younger individuals to participate in boating, ensuring they learn responsible practices under the guidance of experienced adults. By requiring that only certified adults accompany younger operators, the law helps to instill important safety measures and boating etiquette, thereby reducing risks associated with operating more powerful vessels.
