The correct answer is A) They are more seaworthy and less likely to be swamped or broach to. Lifeboats are typically designed as double-enders, meaning they have the same shape at both ends, because this hull form is more stable and seaworthy in rough seas. The symmetrical bow and stern allow the lifeboat to easily ride over waves and avoid being swamped or broaching (turning sideways to the waves). This design feature is important for the safety and effectiveness of lifeboats, which must be able to operate in harsh maritime conditions. The other answer choices do not accurately explain the primary reason for the double-ended design of lifeboats.
