CFD: Driving Continuous Innovation In Wakesurf Boards

Computational Fluid Dynamics, or CFD, is a game changer when it comes to designing anything that flies or floats. Why? The complex models that take humans weeks, months, or years to calculate, CFD can model in minutes or hours.  Engineers use these models to enhance designs and increase performance in aircraft, boats, and more. For example: have you ever noticed that almost all planes have slightly turned up wingtips? Using CFD, aerospace engineers discovered that adding these winglets to airplane wing design decreased drag and reduced the amount of fuel needed to fly.

When Force is Fluid: Using Fluid Dynamics to Inform Wakesurf Board Design

If you've ever tried a skim-style wakesurf board and then switched to surf-style, you’ve likely noticed that they feel and ride completely differently. It makes sense because the former is usually smaller and thinner, while the latter is larger, thicker, and has bigger fins. But why do these design differences change the ride? Is it that bigger boards have more contact with the water, while thinner boards have less volume and buoyancy?

Why does it matter that we define performance?

Why does it matter that we define performance?

Going back to the original idea we started off with I would like to add to it, "you can't improve what you don't measure and you can't measure what you don't define". As a sport and an industry we need to start defining what Performance is, otherwise we will continue to stagnate where the only improvement we will see is by way of randomly prototyping new ideas.

Wakesurf board simulation to define what wakesurf performance is

What is Performance?

Smith Board Co is on a mission to set the industry benchmark in an industry devoid of standardization while pushing it to new heights. The nuance of performance, from board design to rider experience, is complex. But put simply, performance can be defined as the relationship between three main aspects: speed, agility, and air.

What is Computational Fluid Dynamics?

What is Computational Fluid Dynamics?

Computational Fluid Dynamics, or CFD, is a computer modelling technique that analyzes the flow of fluid. It can be used to simulate airplanes in a wind tunnel, or air flow through a combustion engine. At Smith Board Co, we use CFD to simulate and analyze our wakesurf boards so we can build the best boards out there. Read the full article to get an idea of how CFD actually works, it's written so you don't have to be an engineer to understand it!

Unraveling the Mystery of Rocker in Surf vs. Skim Style Boards

Unraveling the Mystery of Rocker in Surf vs. Skim Style Boards

Have you ever wondered why surf style boards boast a significant amount of rocker, while skim style boards remain almost flat? A visit to any board shop might leave you with the simple explanation that "it's just how they are." However, there's more to the story of your board's rocker than meets the eye.

Blunt vs Pin Tail

Why Do Some Wakesurf Boards have Blunt Tails?

Surface Area Advantage: A blunt tail offers a wider surface area at the back of the board. This design translates into increased stability, an attribute especially beneficial for beginner and intermediate riders. It's like having a more forgiving board to maintain balance.

Mastering the 360: Choosing the Right Wakesurf Board for Spinning

Mastering the 360: Choosing the Right Wakesurf Board for Spinning

As your wakesurfing skills progress, you'll naturally be drawn to learning new tricks. One of the first major feats for many riders is mastering the 360 - a full circle rotation on the water, starting and ending in a forward position. Though challenging, understanding the characteristics of a board that aid in spinning can be a significant advantage.
