What is the characteristic shape of a planing cathedral hull?

The characteristic shape of a planing cathedral hull is best represented by the classic Boston Whaler shape. A cathedral hull is designed with a unique multi-hull configuration that provides excellent stability and lift while allowing the boat to plane efficiently at speed. This design typically features a flat bottom with sharp, distinctive edges and wide, splayed out sections at the bow, which help in achieving planing with minimal power and creating a smooth ride over waves.

The Boston Whaler, often associated with this type of hull, showcases the effectiveness of the cathedral design, emphasizing stability and versatility in various water conditions. The shape allows for better fuel efficiency and increased load capacity, making it an ideal choice for recreational boating and fishing. In contrast, other hull shapes like round or V-shaped hulls prioritize different aspects, such as stability or speed, rather than the specific advantages derived from the cathedral hull's design.
