What type of boat is most likely to have a planing hull?

A ski boat is most likely to have a planing hull because planing hulls are designed to rise up and glide on top of the water when traveling at higher speeds. This design is specifically advantageous for activities like water skiing, where maintaining speed and stability is essential for the skier. The narrow and sleek shape of a ski boat allows it to achieve the necessary speed to get up on a plane, reducing drag and increasing performance.

Fishing boats, on the other hand, typically prioritize stability and storage over speed, and may not have the same hull design suited for planing. Pontoon boats generally feature a flat-bottomed design for stability and passenger capacity rather than speed, focusing on leisurely cruising rather than high-speed performance. Tugboats are designed for power and stability to maneuver large ships and typically have displacement hulls that allow them to push through the water, rather than rising above it. Thus, the design characteristics of a ski boat align perfectly with the requirements for a planing hull.
