It may look like a swimming pool, but towing tanks exist for a different purpose. They are a fundamental tool of ship design.
Hydrodynamics And Hull Design

Hydrodynamics and Hull Design

, , ,
A refined hull shape epitomizes the link between tradition and science. When we link the science of ship design with the experience of past ships, we identify the successes and isolate previous failures. This article glimpses into the background of hydrodynamics by exploring the link between the science of Bernoulli’s equation and the shape of ship hulls.

Splitting Waves and Hairs: Comparing X-Bow, Axe Bow, and More

, , , ,
We currently enjoy an explosion of variety in bow shapes, each suited to a different task. Nearly the same bow shape, used on a different hull, may work for entirely different reasons. This time we distinguish between four prevalent bow shapes: conventional hull, X-Bow, Axe Bow, and wave piercing.

How do I Select the Right Hull?

, , , ,
Monohull, catamaran, trimaran . . . so many choices. Which hullform to pick? This article provides a rational and design map for selecting hullforms applicable to any type of mission. This organized approach allows us to see past the limitations of historic examples and consider new alternatives.

Go FAST Boat: Pros and Cons of a Planing Hull

, , ,
Power. Speed. Performance. Planing hulls promise incredible capabilities. But seakeeping, slamming, and low deadweight capability frequently plague planing hulls with design challenges. But if you accept these limitations, the planing hull compacts large capabilities into a small package. Sometimes smaller is better.

The TRUTH of Hull Speed: How to Break the Sailing Speed Limit

, , , ,
Hull speed is bogus, but not because the math is wrong. This formula supposedly predicts the maximum speed of a yacht based solely on length. But don’t sell yourself short; there are ways around speed limits. Today we discuss the basis for hull speed and fill in the rest of the story.
