Board volume, and why the shortboard is the wrong first surfboard

Walk into any surf shop and the boards on the wall that look like the ones professionals ride are the ones beginners want. They are also the ones that will make learning to surf take three times longer than it needs to.

Volume is the number

Every modern board has a volume in litres printed on it, usually near the tail. It is the single most useful specification and the one people ignore in favour of length.

Volume determines flotation, which determines paddle speed, which determines whether you catch waves. A surfer who catches twice as many waves per session improves roughly twice as fast, and everything else — turning, style, wave selection — comes later.

The rough guidance used by shapers relates volume to body weight and ability. A complete beginner may want a volume well above their body weight in kilograms; an intermediate somewhat less; an experienced surfer considerably less again. The exact ratios vary by source and by wave type, but the direction is consistent: less experience means more volume, not less.

Age, fitness and how often you surf all shift it upward too. Someone surfing twice a month needs more float than someone surfing daily.

What the wrong board does to you

A board that is too small does not float you properly. You paddle slower, so you catch fewer waves. You catch them later, so you are always taking off in the steepest part. You spend the session in the whitewater, get tired sooner, and get out having stood up twice.

Meanwhile someone on a board with plenty of volume caught fifteen waves, stood up on ten, and got an hour of actual practice at riding.

Progress in surfing is a function of waves ridden. Almost nothing else matters at the start.

The sensible progression

Foam board, generously sized. Soft top, thick, long. Catches everything, forgiving of poor technique, and — importantly — safe. A hard board with a sharp nose and fins is genuinely dangerous to the rider and to anyone nearby while board control is unreliable.

Stay on this until you can consistently catch unbroken waves, stand up reliably, and angle along the face rather than going straight.

Then a mid-length or a funboard. Still plenty of volume, more responsive, harder rails. This stage teaches turning and wave selection and it lasts longer than most people want it to.

Then, gradually, less volume. Small steps, over seasons. Each reduction should be consolidated before the next.

The rushed version of this progression is the single most common reason people plateau or give up.

Length, width and thickness

Length gives paddle speed and stability in a straight line, at the cost of manoeuvrability.

Width gives stability and flotation, particularly through the middle, at the cost of rail-to-rail speed.

Thickness gives volume without length, which is how modern shorter boards achieve float. It also makes rails thicker, which can make them harder to engage.

These interact, which is exactly why volume is the useful summary figure rather than any single dimension.

Rocker, rails and tails, briefly

Rocker is the curve from nose to tail. More rocker fits steeper waves and turns tighter; less rocker paddles and glides faster. Beginners want flatter.

Rails — the edges — determine how the board holds in a face. Fuller, softer rails are forgiving; thin, hard rails hold better and catch more easily.

Tail shape affects release and hold. Wider tails plane and are looser in small waves; narrower, pintail shapes hold in steeper, faster water.

These matter genuinely at an intermediate level and almost not at all before that.

Match the board to your waves

Not to the waves in the video. If you surf small, weak beach breaks most weekends, a board designed for hollow reef is the wrong tool and will make every session worse.

Most people are better served by a board that works well in the conditions they actually get eighty percent of the time.

Second-hand is fine, and a good idea

Boards hold up well and you will outgrow whatever you buy first. Buy used, ride it for a season, sell it, buy the next one. Check for delamination, water ingress around the fin boxes and leash plug, and pressure dings that have gone through.

And borrow before you buy where you can. Half an hour on a board tells you what an hour of reading cannot.
