Volume directly tells you how much float your surfboard has. With the rise of shapers using CDC machines to help them shape, surfboard makers can now keep track of volume, though it can be imperfect at best. When boards were primarily hand shaped, no one knew how many liters were in a given board. Volume is a pretty new metric for measuring dimension and is measured in liters even though everything else in surfing doesn’t use the metric system. Thinner rails can more easily bite into the face of the wave giving you more control. This can make it hard to keep control if you are going fast or are surfing larger, powerful surf. Thicker rails are hard to engage in the water when you turn. It may seem like it’s always better to have thick rails then if it keeps your surfboard buoyant. Boards with straight rails that maintain a similar width through the whole surfboard will go much faster. However, these outlines are slower on the wave face. The more leaf-like the outline, the easier it is to have a wide base but still be able to turn. One other thing to mention about width has to do with outlines. But if you are becoming more and more experienced, you may find that you want to get a narrower board. It can feel like standing on a table which is a good thing if you are just learning how to surf. The downside of having a really wide board is that it becomes very hard to turn. The number you see for width describes how wide your surfboard is at its widest point. That answer will determine how long your board should be in a general sense of longer or shorter.Ī surfboard's width will determine how stable the board feels under your feet. When looking for surfboards, you want to decide what you need more: paddle power or maneuverability. This is why surfers prefer shorter boards in more critical surf. Since there is less length, there is less board in front of you that can nose dive in the water and through you off. Shorter surfboards are also easier to ride when the waves become steeper. Going back to our example, changing direction on the 6 foot surfboard is far easier than a log. When it comes to turning your board, the shorter board will be much easier to throw around. This is just due to the amount of momentum each is able to build and how well the board can plane on the water. If you get a 9 foot log, it will go much faster than a 6 foot shortboard. The longer your board, the easier will paddle. We have made some assumptions about the average size and shape of various surfboard styles, and used this to categorise the formula into the three surfboard shapes available in the calculator.Length most noticeably affects your ability to paddle and turn. The logic is derived from comparing a large amount of data of known surfboard dimensions and volumes, and then building a formula based on this data. The calculator takes a much more simple approach to provide an approximate value. There are alternate methods such as measuring the weight required to completely submerse the board, but this becomes tricky with Soft Top Surfboards and the variable boyancy. dunk your surfboard into a giant bathtub then measure how much is spilled onto the floor! Even the simple submersion method is still quite complex, as you need to submerge the surfboard into a vessel of water with a known quantity, and then measure how much is dispersed. To accurately measure the volume of a surfboard you need to use software to measure it from the CAD drawings or use a submersion technique. Surfboards that are too bouyant can also feel less stable as you feel like you are balancing on top of the water, rather than in the water. Imagine two copies of the same board, but one with the fins mounted at the other end and how different these would be to surf!Ī surfboard with higher volume will typically be easier to paddle and to catch waves, however it will usually be slower to turn and harder to duck-dive under waves. Two surfboards can share identical volume but feel quite different in the water due to where that volume is located in the board. It is however crucial to understand that volume on it’s own does not dictate the performance of a surfboard, and the shape has a major role. Surfboard volume is a major factor to consider when choosing your next surfboard and comparing the volume of similar shape and length surfboards is one of the best ways to understand really how much difference there is as it summarises all the measurements. As surfboards float, this means that more volume = more buoyancy. The greater the volume, the greater the amount of water that is displaced when trying to submerse the surfboard. Volume refers to the size of the total area of a surfboard.
