Surfboard Volume
Find Ideal Volume
Volume should be a guide, not a rule, and this chart can help you figure out a good ballpark volume for you to base your boards off of.
Ability/weight/volume numbers are not exact science, but will give you an idea of where to start. This chart is assuming that we are talking about a basic performance board to be ridden in average/good waves.
- Generally speaking you would want to ADD volume for a board designed for smaller, weaker conditions
- You would ADD volume for a step-up board for use in bigger, more powerful waves
- Wearing a lot of rubber (thick wetsuit, booties, etc.) adds to your weight and diminishes paddle power, so ADDING a little additional foam will help you.
- You want to balance the added ease of paddling (more volume) with sensitivity and performance (less volume)

Timmy Patterson S-Twin Surfboard
Experience the Refined Power of the S-Twin by Timmy Patterson
Crafted by renowned shaper Timmy Patterson, the S-Twin surfboard is a masterclass in blending classic design with high-performance innovation. Drawing inspiration from the timeless Sherman round nose fish outline, Patterson has continuously refined this shape through close collaboration with surfers around the world. The result is a board that feels fast, responsive, and remarkably versatile—whether you're paddling out on the North Shore, surfing the beach breaks of Brazil, or chasing lines in California.
At the heart of the S-Twin’s design is its distinctive single wing swallow tail, which allows for a more pulled-in tail block. This design detail, paired with a wider outline, creates exceptional rail-to-rail responsiveness and maintains impressive drive and speed down the line. A subtle single concave runs through the front of the board and transitions to a vee off the tail, helping the board stay quick and nimble even in weak, gutless waves. The vee bottom enhances control, locking the board into turns with smooth, fluid transitions.
Engineered with a low rocker, the S-Twin is built to shine in smaller, softer surf, yet remains a reliable go-to for year-round conditions. Designed specifically for a twin fin setup with a small center trailer, it invites creativity and unlocks a playful, skatey feel without sacrificing control. Whether you prefer added volume in a longer board or want to push limits with a shorter, fuller template, the S-Twin offers flexibility in size and performance. Built by Surftech using their advanced Fusion Pro EPS/Epoxy construction, this board delivers a lightweight yet durable ride with enhanced responsiveness and longevity.
The Fusion Pro build ensures that every turn, carve, and pump is met with lively feedback and lasting strength. The S-Twin is more than a surfboard—it’s a platform for progression, designed by one of the best and constructed to perform.

JACK'S SURFBOARDS
SURFBOARD BUYING GUIDE
Choosing your next surfboard isn’t about chasing trends — it’s about finding a board that matches your skill level, wave conditions, body type, and surf goals. This guide was created by the Jacks Surfboards team to help you confidently choose your next board, whether you’re building your first quiver or fine-tuning a well-earned lineup.
