In which mode does a vessel cause a large wake and reduce operator visibility?

The correct choice is planing mode, which refers to the state in which a vessel is lifted out of the water as it gains speed. In this mode, the hull is designed to ride on top of the water rather than pushing through it. As the speed increases, the boat creates a significant wake due to the large volume of water displaced by the hull. This wake can be substantial, causing potential hazards for other vessels and contributing to shoreline erosion.

Additionally, when a vessel is in planing mode, operator visibility may be compromised. The speed can cause water spray, and the angle of the vessel can make it difficult for the operator to see ahead clearly. The combination of a large wake and reduced visibility in planing mode highlights the importance of careful operation and awareness of surroundings while navigating at speed.

Displacement mode, on the other hand, is characterized by the vessel moving through the water with the hull submerged, resulting in minimal wake and better visibility. Static mode refers to a vessel not moving, which obviously wouldn't create any wake or visibility issues, while steady mode does not specifically pertain to a recognized operational state that would impact wake or visibility.
