What precaution should be taken when climbing onto a capsized boat?

Using a flotation device when climbing onto a capsized boat is crucial for several reasons. First, a flotation device provides immediate buoyancy, which can prevent the person from becoming overwhelmed by water and can assist them in staying afloat, especially if they are fatigued or disoriented from the incident. It also helps maintain orientation and stability while attempting to get onto a capsized boat, as the water conditions may be unpredictable.

Additionally, using a flotation device enhances personal safety by minimizing the risk of drowning. In emergency situations like this, maintaining safety should be the top priority, and having that extra measure of support can make a significant difference in the outcome. The other choices either pose a higher risk of injury or do not prioritize safety, making the use of a flotation device the best and most sensible decision in this scenario.
