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

Axe bow, X-bow; slim size, thin size.  We currently enjoy an explosion of variety in bow shapes, each suited to a different task.  These may all look the same with a cursory glance, but don’t get fooled.  Nearly the same bow shape, used on a different vessel may work...
How do I Select the Right Hull?

How do I Select the Right Hull?

Monohull, catamaran, trimaran . . . so many choices.  Which hullform to pick?  Can we draw upon any science to guide our choices, or shall we beg Lady Luck to guide us?  Although hullform selection does involve some experience and artistic preference, naval architects...

Go FAST Boat: Pros and Cons of a Planing Hull

ZOOM!!!  No better way to describe planing boats.  They pack very fast speeds into a very small package.  Many planing boats achieve speeds well beyond the limits of larger craft.  How do they do it?  And what are the penalties for this extreme speed?  Discover if a...

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.  It gets discussed frequently in sailing yacht communities.  Surprisingly, hull speed is partially correct, with a very...
