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)

Stewart Hydrocush Ripster
Stock Dimensions: 9'6" x 23 1/2" x 3 1/4"
Volume: 79.82 L
Fin included!
The HydroCush Ripster board takes “maximizing fun” to a whole new level! Don’t call it a soft top - these boards are so much more. The HydroCush line combines a hard bottom including all of the high-performance features that Stewart shapes are known for with a user-friendly EVA foam deck. The result is a board that is more durable than a glassed board, safer than a hard board, and rides way better than a foamie. What’s more fun than that?
Every Stewart HydroCush board is built to last and made to advance your surfing while putting a smile on your face!
A shaped EPS blank makes up the core of the Stewart HydroCush boards, hand-finished with precision and the highest attention to detail. Perfectly blended concaves and flawlessly foiled rails make these boards faster, looser, and more responsive than you ever thought a soft top could be. A real wood stringer from tip to tail provides the ideal flex and a wood veneer wrap maxes out strength and durability. Custom EVA on the deck gives it a surprisingly soft yet grippy feel. HydroCush is your magic carpet to fun — no need for messy wax. This unique construction will make your turns feel solid and stable, while the time-tested, tried and true Stewart shapes ensure responsiveness and unparalleled performance.
The best of both worlds, the HydroCush Ripster combines classic styling with modern technical design features, making it the ideal performance single fin!
A deep, long blended concave in the nose makes this board paddle with maximum glide to catch every wave. It also creates trim speed and lift down the line, beating sections like you won't believe! The rails are down hard in the tail, then soften as they go forward, making the Ripster turn incredibly well while also being forgiving. The hard edges on the tail release water, giving it ripping speed, and the foil holds it in the pocket. The heavy V in the tail runs up to the middle of the board, where it's perfectly transitioned into the nose concave. This makes rail to rail surfing easier, and beautiful back-to-back roundhouse turns effortless. Finished off with a clean & simple raked 9" single fin, for that classic look and optimal performance for this model.
Fiberglass center fin included.
