What type of propelling gear is required on a lifeboat that is not motorized?

The correct answer is that the propelling gear on a lifeboat that is not motorized must be of approved type and sufficient power. This requirement is critical for ensuring the safety and effectiveness of the lifeboat in emergency situations.

Lifeboats are designed for use in emergencies, and their ability to maneuver and respond to situational demands relies heavily on their propelling gear. The requirement for the gear to be of an approved type ensures that it meets specific safety standards and regulations established by maritime authorities, such as the International Maritime Organization (IMO).

Moreover, the need for sufficient power ensures that the lifeboat can operate effectively during rescue operations or in adverse conditions. This power might come from oars, sails, or other manual means of propulsion, depending on the design of the lifeboat, but it must be sufficient to provide the necessary maneuverability.

Other options either do not provide sufficient criteria for safety and effectiveness (e.g., “of any type” could include unapproved or unsuitable gear) or incorrectly limit the means of propulsion to specific types that may not be applicable or practical in all situations.
