Hemp in the surfboard: Why the new eco-wave is more than a green label

From hemp laminates and bio-resins to recycled cores and green hardware: the surf scene is looking for boards that ride well – and leave less of a mess behind.

Surfing feels natural. But the classic surfboard itself is often anything but natural.

Surfing feels like freedom: salty water, sun on your face, barefoot vibes. At the same time, it’s a bit absurd what most boards are built with: foam cores made of petrochemicals, fiberglass, polyester resin—materials that can be hazardous to your health in the workshop and are difficult or impossible to recycle in the end.

Board builders are openly addressing this paradox. A scene that relies so heavily on nature, water, coastlines, and weather must inevitably ask how sustainable its materials actually are.

The good news: a lot is happening in the surf scene right now, and hemp is playing a surprisingly big role. Not as a hyped-up fiber, but as a serious material for performance and sustainability—from hemp laminates and bio-resins to hemp-based fins.

Why the classic surfboard is an environmental problem

A modern standard board usually has a similar construction: a foam core made of PU or EPS, fiberglass reinforcement, and a resin system made of polyester or epoxy. It's light, stable, and has been the industry standard for decades—but it's not exactly "sweet" when it comes to ecology and health.

Laminating and sanding create fumes and dust. On top of that, you end up with a product that is hardly circular. A broken board can often be repaired, but rarely truly recycled.

And that's exactly where the new eco-wave comes in: fewer toxic vibes in production, more renewable materials, more recycled content—without the board feeling like a soggy cardboard box.

The most exciting development in board building isn't just "greener." It’s more technical, more conscious, and often closer to real performance than many think.

What hemp in a surfboard really adds

Hemp in a surfboard might sound like an eco-story at first. In fact, the material is much more interesting. Hemp is not only fast-growing, but as a fiber, it is also robust, resilient, and technically exciting when combined with resins.

The important thing to note is that a natural fiber doesn't automatically outperform fiberglass in every category. But when processed cleverly, it can deliver a really good mix: solid stability, pleasant flex characteristics, and a unique ride feel.

Vibration damping: less chatter, more flow

Natural fibers like hemp and flax often have higher vibration damping in composites than classic synthetic fibers. For sports equipment—and yes, surfboards absolutely count—this is exactly what makes them interesting.

Translated to the lineup: The board can feel smoother, especially when the water gets choppy. Less chatter, more control, more flow.

Hemp isn't just a sustainability choice. In composites, the fiber can also change the way the board rides.

Hemp vs. flax: Why you see "flax" so often

When you read about eco-boards, flax—linen—comes up extremely often. The reason is pragmatic: flax is widely available in consistent composite quality, whereas hemp can fluctuate more depending on the supply chain and quality.

A composite specialist put it roughly like this: Hemp has potential, but standard mass-produced hemp fibers don't always beat standard flax—at least not without special processing.

However, this doesn't mean hemp is out. Rather, it means hemp is a material you have to choose deliberately—which is exactly why it remains exciting.

Eco-upgrade #1: Bio-based resins

Even if you laminate with hemp, if you use a classic resin, a large part of the environmental load remains. That's why many eco-concepts push bio-based epoxy systems.

Big names in this field include Entropy Resins and Super Sap. The brand emphasizes bio-based, certifiable content and works with life cycle analyses to make the impact measurable. Such resins are also used and discussed in the context of surfboards.

This point is important because many people only look at the fabric when talking about sustainability. But resin is often the game-changer for toxicity, emissions, and footprint.

When it comes to an eco-board, it's not just the fiber that decides. The resin is often half the battle.

Eco-upgrade #2: Cores, recycled content, and smarter foam

The core is the volume you paddle—and also a huge part of the material used. Many eco-approaches therefore rely on recycled or partially recycled foams, improved EPS cores, and alternative experimental material systems.

An example of how concrete this can look is shown by Notox from the Basque Country: one of their eco-constructions utilizes a foam core with recycled content and a resin with plant-based ingredients.

Case study: Notox and the journey from eco to big-wave capable

When many people think of sustainable boards, they first think of soft, cozy, and perhaps for small waves. But that is no longer the case. Notox is a good example of how eco-materials have long moved into high-performance contexts – right up to boards that show up in truly heavy conditions.

In 2024, reports emerged of tow-in boards built for Nazaré and big-wave competitions that utilize more sustainable material combinations.

The material mix is also exciting: natural fibers, often flax or linen in the case of Notox, combined with bio-based resins and, in some cases, recycled or upcycled components. So, it's not dogmatically 100 percent plant-based, but performance-first with impact reduction.

In modern board building, sustainable does not mean less performance. It means making better choices for every single component.

Hemp isn’t just for the deck: fins and hardware are also getting greener

Let's be honest: many eco-boards are celebrated – and then people screw fins underneath that are completely standard. Things are starting to move there as well.

There are fin series that work with a hemp base, cork core, and bamboo tip. Sounds like Pinterest, but it's actually quite logical: hemp provides stability, cork saves weight, and bamboo controls flex.

Specialist media have also described bio-composite fins as a field of development, because stiffness, weight, and performance have to be just right. Sustainability only works here if the material performs well in the water.

The certification corner: ECOBOARD as a reality check

If you don't want to read every data sheet yourself, the ECOBOARD Project framework by Sustainable Surf is a well-known orientation system in the surf world. It’s not about "we are green, trust us," but about defined criteria.

This includes, for example, resins with bio-based content and low VOCs, core material with recycled or plant-based components, verification, transparency, and sometimes references to life-cycle analyses.

Many brands communicate ECOBOARD levels like Gold as a signal: we meet defined minimum standards, not just marketing.

Future stuff: Can you grow a surfboard?

Now it gets wild – but in a good way: In 2018, the Technical University of Denmark reported on a team that uses hemp fibers and fungal mycelium to grow a biodegradable board in a mold.

The idea: Mycelium grows as a natural binder, hemp provides structure. Is this already mainstream? No. But it shows where the journey is heading: away from pure petrochemical materials and towards material systems that take circularity truly seriously.

The future of the surfboard might smell less like a chemical factory – and more like material systems that grow, dampen, hold, and eventually disappear again.

What you can look for when buying

You don't have to be a materials scientist to make better choices. Often, just a few questions are enough to distinguish true eco-thinking from green window dressing.

For DIY crews and shaper nerds

Hemp fabric can behave differently than fiberglass during lamination. Resin absorption, handling, and finish can be more demanding. This has been discussed in the board-building community for years – often as a hybrid layup of hemp and glass or in specific zones, such as for deck patches.

When a shop offers accessories, this is exactly where interesting product worlds arise: hemp fabric, bio-based resins, eco-fins, protective equipment, and repair kits.

Sustainability does not mean less performance. It means better choices for every single component.

Hemp in board building is not "plug and play." But that's exactly where it gets exciting, where materials are used consciously.

Conclusion: Hemp is not a gimmick

The surf industry is currently in a phase where style and science meet. Natural fibers provide new riding characteristics, bio-resins reduce toxicity and footprint, recycled content makes cores smarter – and individual projects are even thinking in terms of completely biodegradable structures.

Hemp is not the only hero here, but it is a pretty strong character in the cast. It represents a new way of thinking about materials: not as green decoration, but as part of a board that brings performance, aesthetics, and responsibility together better.
