Why Does My Paddle Board Sink in the Middle?

July 27, 2022 4 min read

If your paddle board sinks in the middle, you may not have a good construction. Here are some tips. Check the stringer, High volume, EPS foam, and construction methods. Often, it's not the builder's fault. Instead, it's the board itself. If your paddle board sinks in the middle, it's probably a combination of these problems.

High Volume

A high volume paddle board is a great choice if you want to have more buoyancy than a low-volume model. Inflatable paddle boards are typically 160-380 liters. A board with too little volume will feel unstable while one with too much will drag through the water. A good rule of thumb is to multiply your weight by 1.4 to determine the maximum volume. If you are carrying around ten pounds of gear, look for a 266 liter model.


There are several reasons why Stringer's paddle board sinks in its center. A wooden paddle board tends to sink at the middle, while a carbon one tends to rise in the middle. The two types of paddle boards differ in construction, but the majority of paddle boards are made with wood stringers. A carbon or wood stringer can increase the overall strength of the paddle board. The most important thing to consider when purchasing a paddle board is the stringer's construction.

When you are standing up, keep your knees bent and your core centered over the board. It will be easier to keep your balance if you bury your paddle into the water, but you should also keep in mind the importance of balancing on the board. If you fall, try to get back up slowly and correct yourself so that you don't fall on your board. Practice paddling with one foot at a time until you find a stable spot.

EPS Foam

If your SUP is sinking in the middle, the problem is likely with the EPS foam. If this is the case, you should look at the EPS foam's density and make sure that it is at least 3mm thick. Padding can also be helpful in preventing the board from sinking too much. The padding can also prevent the edges of the paddle board from catching on your feet while turning.

When a SUP board starts sinking in the middle, it could be because it has a crack or other damage in its EPS foam. If this happens, you should stop paddling it immediately and check for cracks. You may see foaming or bubbling around the cracks. The board could also be leaking from its fin box. If it has a crack, check the fin box for leaks before relaunching.

Construction Methods

Inflatable paddle boards may sink in the middle. This can be caused by the construction methods used. Single layer construction, for example, is much lighter and cheaper, but it's also not as durable. Single-layer construction utilizes a single layer of drop-stitch material on the top and bottom, and a layer of PVC on the rails. However, single-layer dropstitch material is not airtight on its own. Therefore, a second layer of PVC is poured over the top of the drop-stitch material, forming a seal that keeps the board stable and upright.

Paddle boards constructed with wood or carbon can also sink in the middle. Luckily, some manufacturers have found a solution to the problem. Inflatable paddle boards can be made with EPS foam, which is a closed-cell material that doesn't absorb water. The same material is used to create coolers, which are also airtight. By eliminating the layers of glue or adhesive, Paddle boards are incredibly durable.

Buying a Case

Inflatable SUPs don't always come with a carrying case, so make sure to purchase one. A carrying case will help keep your board and paddle together, as well as any extra accessories. Make sure your case has a cinch strap so nothing will shift and get lost inside it. And don't forget to buy a carrying case with straps around the shoulders and waist!

Inflatable standup paddle boards are made of multiple layers of PVC fabric over dropstitch fabric. Hardboards are a bit more durable than inflatables, but they're also less stable. Because of their thickness profile, inflatables are great if you don't have a lot of room to store them. Inflatable paddle boards can also fit in a suitcase and on a plane. And they're much less expensive. Hardboards are made of fiberglass and epoxy resin, and some are hollow or plastic.

Common Mistakes Made By First-Timers

Among the most common mistakes made by first-timers when using a paddle board is not knowing how to properly position their blade. While this topic is usually covered in paddle board lessons, it's important for first-timers to follow the steps outlined in this article. To avoid making any of these mistakes, it's best to take a few minutes to read through the guidelines for proper blade positioning before getting on your board.

Incorrectly holding the paddle. Most paddleboarders hold the paddle backwards, causing it to wander. In order to prevent this, you should hold it vertically. This will ensure maximum forward projection, minimize sideways movement, and help you paddle faster. Here are some other tips for proper paddle board technique:
