What should be done after boarding a liferaft in terms of survival position?

After boarding a liferaft, assuming a huddled position for warmth is essential for survival. This posture helps conserve body heat, which is vital in a survival situation, particularly in cold water or environments where hypothermia could occur. By staying close together, individuals in the liferaft can share body warmth, reducing the risk of hypothermia and increasing the chances of maintaining body temperature.

In addition to conserving heat, this position also helps to provide a sense of security and stability within the raft, as it minimizes movement and helps maintain balance. The grouping of individuals enhances emotional support and camaraderie, which can be crucial in stressful situations.

The other options do not adequately address the critical need for body warmth and efficient use of space within the raft. Sitting or standing may expose individuals to the elements and may lead to quicker loss of body heat.
