Question 150Safety & Environmental - QMED

The correct answer is A) unbalanced rudders. Most lifeboats are equipped with unbalanced rudders, which means the rudder is attached to the boat in a way that makes it asymmetrical. This design helps the lifeboat maintain better control and maneuverability, especially in rough seas and high winds, which are common conditions that lifeboats may encounter. The unbalanced design gives the rudder more leverage and responsiveness compared to a balanced or straight rudder. The other options are incorrect because balanced rudders are typically found on larger vessels, contra-guide rudders are a specialized design not commonly used in lifeboats, and straight rudders would not provide the same level of control and maneuverability required for a lifeboat.
