Suspenz EZ-V Universal Kayak Blocks: Best Overall

The Suspenz EZ-V blocks stand out because of their signature V-shape, which cradles the hull and distributes weight across a larger surface area. This design prevents the pressure points that often lead to indentations or hull distortion in rotomolded or composite kayaks.

These blocks are constructed from high-density EVA foam that resists compression even under the weight of heavier fishing kayaks. They remain stable on most indoor surfaces, making them ideal for someone who needs to set up a quick, secure storage station in a garage or basement.

For the serious paddler who values gear integrity above all else, these blocks are the gold standard. They bridge the gap between heavy-duty wall mounts and makeshift solutions, offering professional-grade support that is easy to move and store.

Malone Universal Kayak Block: Most Versatile

When versatility is the priority, the Malone Universal Kayak Block shines as a reliable multi-purpose tool. While these blocks excel at cushioning a kayak on the garage floor, they are equally capable of serving as temporary roof rack padding during transport.

The blocks feature a non-skid underside, which is a critical feature when placing them on slick concrete or painted wood surfaces. By preventing the blocks from sliding outward, the design ensures the kayak remains perfectly balanced while being loaded or unloaded.

Choose this option if the storage solution needs to pull double duty for travel. It provides enough stability for long-term indoor storage while maintaining the portability required for weekend road trips to the launch site.

Seattle Sports SUP Blocks: Top Pick for Paddleboards

Stand-up paddleboards require a flatter support surface than kayaks to avoid damaging the deck pads or fin boxes. The Seattle Sports SUP Blocks are engineered specifically with this profile in mind, offering a wider, flatter base that accommodates the sleek lines of a surfboard or SUP.

Because these blocks are made from closed-cell foam, they do not absorb moisture or harbor mildew if placed on damp concrete. This is a vital consideration for anyone storing equipment in a basement or near a utility sink where humidity levels might fluctuate.

Anyone protecting an expensive carbon fiber or epoxy board should prioritize these blocks over generic V-shaped options. They provide the necessary surface area to ensure the board remains flat, effectively preventing the dreaded “oil can” effect that ruins board performance.

Rad Sportz Kayak Storage Blocks: Best Budget Option

The Rad Sportz blocks prove that effective storage does not have to be an expensive endeavor. These basic, functional foam blocks offer a straightforward cradle for your boat without the added cost of proprietary materials or complex geometry.

They are lightweight and incredibly easy to tuck away into a drawer once the paddling season begins and the boat moves back to the water. While they lack the premium density of top-tier brands, they are more than adequate for lightweight recreational kayaks that aren’t prone to heavy deformation.

If the goal is to keep a boat off the ground for a low price, these are the ideal choice. They provide exactly the right amount of clearance to keep the hull safe from moisture and debris without breaking the bank.

attwood Universal Kayak/Canoe Holders: Top Value

Attwood has long been a staple in marine recreation, and their universal holders represent a sensible balance between cost and build quality. These blocks are slightly firmer than average, which helps them maintain their shape over extended periods of time.

The design is intentionally simple, featuring a grooved top that accepts both narrow and wide gunwales. This adaptability makes them a fantastic choice for multi-boat households where the storage space might need to accommodate a canoe one day and a kayak the next.

These blocks are best for the user who wants a “set it and forget it” solution. They offer enough durability to justify the purchase, yet they are affordable enough to buy multiple sets for organizing an entire fleet of watercraft.

Onefeng Sports V-Shape Blocks: For V-Hull Kayaks

Not all kayaks are created equal, and those with pronounced V-hulls often struggle to sit securely on flat or generic foam blocks. Onefeng Sports addresses this with a deep-channel V-design that encourages the boat to nestle into the center of the foam.

This deep cradle effectively prevents the kayak from rolling side-to-side, which is a common hazard in high-traffic garages. By locking the hull into the center, the block reduces the mechanical stress placed on the kayak’s sides during storage.

For owners of high-performance touring or sea kayaks, these blocks are a necessity. The deep V-shape provides the structural support needed to keep delicate, thin-walled hulls from warping under their own weight.

How to Properly Position Blocks Under Your Kayak

Proper positioning is just as important as the quality of the block itself. Place the blocks near the bulkheads or at the stiffest points of the hull, usually about one-third of the way in from the bow and stern. Never place support blocks under the very ends of the boat, as these areas lack the structural integrity to support the weight and may crack.

Ensure the blocks are aligned perfectly parallel to one another. If they are skewed, the boat will sit at a torque, which leads to permanent hull distortion over a single winter season. Always check that the hull is centered in the cradle; an off-center kayak puts lopsided pressure on the gunwales.

Finally, keep in mind that indoor floors are rarely perfectly level. Use a small shim under the base of one block if the floor slopes toward a drain, ensuring the kayak remains perfectly horizontal. This attention to detail prevents internal tension from building up while the boat is in storage.

Choosing Blocks: Foam Density and Shape Matter

Foam density is the primary factor in how long a block will last. Low-density foam often flattens out after only a few months, effectively rendering it useless for long-term weight distribution. Seek out closed-cell EVA foam, which holds its shape against constant pressure and resists tearing.

Shape should be determined entirely by the hull design of the craft. Deep-V boats require deep-channel blocks, while sit-on-top kayaks with flatter bottoms benefit from blocks with wider, shallower cradles. Using the wrong shape creates pressure points, which can lead to stress cracks in plastic or delamination in composites.

Do not overlook the base of the block either. A textured or rubberized bottom is necessary to prevent the storage system from migrating across a smooth garage floor. Stability is the foundation of safety, so prioritize high-friction materials on the underside.

Storing Your SUP or Surfboard on Foam Blocks

Storing an SUP or surfboard on foam blocks requires a different approach than a kayak. Because these boards are designed for buoyancy and rigidity, they must be supported across a wide, flat span to avoid stress fractures. Never rest a board on its side; always store it deck-up or bottom-up on at least two wide, flat-topped foam blocks.

Place the blocks no more than 24 inches from the nose and tail to support the board’s structural rails. Avoid storing these boards in direct sunlight, even indoors, as UV rays will degrade the foam blocks and potentially overheat the board’s core if it is a heat-sensitive epoxy construction.

For long-term storage, check the board periodically to ensure the blocks haven’t compressed unevenly. A quick rotation of the board—flipping it from deck-up to bottom-up—every few months can prevent long-term pressure marks from developing in the foam padding.

Can I Use Pool Noodles Instead of Storage Blocks?

While it might be tempting to repurpose pool noodles for storage, this is generally ill-advised for long-term use. Pool noodles are made from low-density, open-cell foam that is designed to support the weight of a person in water, not the static weight of a rigid boat on solid ground.

Under the weight of a kayak, a pool noodle will compress instantly, losing its shape and failing to provide the required support. This results in the hull coming into contact with the hard floor, which defeats the entire purpose of using a barrier in the first place.

Furthermore, most pool noodles lack the UV resistance or structural integrity required to stand up to temperature fluctuations in an uninsulated garage. Stick to purpose-built, high-density blocks that provide reliable, consistent support for your gear.

Proper storage is the best way to extend the lifespan of your paddle gear, ensuring it stays in peak condition from the first warm day of spring to the final paddle of the season. By selecting the right foam blocks for your specific hull shape and weight, you create a stable, protected environment that prevents costly structural damage. Keep the gear off the floor, keep it balanced, and you will spend far more time on the water and less time repairing your equipment.
