Which of the following actions could help prevent a capsizing?

Taking the wake from another boat head on, or off the bow, is an effective action to help prevent capsizing. When a boat encounters a wake from another vessel, approaching it head on minimizes the impact and the angle at which the boat hits the wave. This alignment allows the boat to ride over the waves more smoothly, significantly reducing the risk of rolling or tipping over. By facing the waves directly, the boat maintains stability and control, which is crucial in preventing capsizing.

Maintaining speed in tight turns can actually increase the likelihood of capsizing due to the forces and momentum at play, while carrying extra passengers to distribute weight does not necessarily balance the boat effectively. Keeping the boat near the shoreline might help in certain situations, but it does not directly prevent capsizing in the face of rough waters or wakes.
