Which hull design is known to require more power to achieve the same speed as flat-bottom hulls?

The deep Vee hull design is characterized by its sharp angle and pointed bow, which allows it to cut through waves more effectively. However, this design also results in increased resistance when compared to flat-bottom hulls. As a result, more power is needed to achieve the same speed. The deep Vee shape promotes stability and a smoother ride in rough water, making it preferable for offshore or choppy conditions, but this advantage comes at the cost of requiring a greater amount of engine power to reach comparable speeds seen with flat-bottom hull designs.

Flat-bottom hulls, by contrast, are designed to provide stability on calm waters and require less power to achieve similar speeds, as they have a more efficient shape for moving through less turbulent waters. Other designs, like round bottom or multi-hulls, also have different performance characteristics, but it is the deep Vee hull specifically that requires extra power to overcome its inherent resistance in water.
