Which hull type produces a larger wake due to its box-shaped hull?

• A. Planing hull
• B. Catamaran
• C. Displacement hull
• D. Semi-displacement hull

Answer: (C)

Wake size comes from how much water the hull has to push aside and how abruptly it disturbs the water as it moves. A box-shaped hull presents flat, vertical sides and a broad cross-section that displaces a larger volume of water and disrupts the flow more suddenly. That energy goes into forming waves behind the boat, so the wake tends to be larger. Planing hulls lift up and ride on the surface, reducing underwater disturbance and often producing smaller wakes. A catamaran splits the flow with two slender hulls, which also tends to reduce wake height, and a semi-displacement hull sits between the two. So, the displacement hull is the one that typically creates a larger wake due to its boxy form.
