What is strictly prohibited when renting an MWR vessel?

The correct answer highlights a key regulation within the MWR vessel rental guidelines. The prohibition against sharing the vessel with non-registered persons is based on safety and liability concerns. When you register to rent a vessel, your information is documented, and the rental agency needs to ensure that all individuals aboard are accounted for in case of emergencies. This approach helps maintain control over the activity and ensures that all passengers are briefed on safety protocols.

Following the 1/3 fuel rule, which refers to keeping one-third of the fuel in reserve for safety when returning to shore, is actually a best practice for boat operation and is encouraged rather than prohibited. Leaving valuables on board, while typically advised against for security reasons, does not inherently violate the rental agreement but poses personal risks. Unauthorized use of the vessel can jeopardize the safety of the individuals on board and violate legal agreements, making it a serious offense within rental terms. Thus, the prohibition against sharing the vessel with non-registered persons stands out as an essential rule to follow for safety and liability purposes.
