How many transmissions are equipped on the boat?

The boat is designed with two transmissions to ensure optimal performance and reliability in various marine conditions. Having dual transmissions allows for redundancy, meaning if one transmission fails, the other can take over to maintain functionality. This feature is particularly important in rescue operations where reliability is critical. Additionally, two transmissions can enhance maneuverability and control, which is vital when navigating challenging environments or executing complex rescue maneuvers. This setup provides the vessel with increased torque and thrust, aiding in rapid response and precise movements during rescue missions. Such considerations highlight the importance of having multiple transmissions in a rescue boat, underscoring why two is the correct answer.
