Designing Your Surfboard

Designing your own surfboard? Sweet! It’s a great chance to express your creativity. Here’s a guide on how to make it right.

  1. First, pick the materials that suit you.
  2. Then, mould the board according to your fancies.

Let’s get going!

The difference between board shapes

Surfboard shape is key when it comes to how it behaves in the water. Let’s look at the six most usual shapes:

  1. Shortboard: Small, light, and made to do high-performance surfing. It has a pointed nose and a narrow tail, allowing for easy turning and quick manoeuvring in waves.
  2. Fish: Wider and shorter than shortboards. Round nose and swallowtail. Ideal for small waves and good for speed, not as good for turning.
  3. Funboard: Suitable for all skill levels. Wider than a shortboard, with a rounded nose and fuller rails for stability and catching waves.
  4. Longboard: Great for beginners. Stable and easy to paddle. Longer and heavier than a shortboard, with a rounded nose and tail, for a smooth ride.
  5. Gun: For riding big waves. Long and slim, with a pointed nose and a narrow tail. Often made from special materials to cope with massive waves.
  6. Hybrid: Combines two or more traditional shapes. Good for surfers who want both worlds.

Tip: Select the right board shape for the best surfing experience. Try different shapes to find the one that feels comfy and works for your style.

Determining board dimensions

Designing a surfboard? Super important to get the dimensions right. Here’s how:

  • Weight & height, plus your skill level, decide the volume.
  • Think about the waves & destination conditions.
  • Shape, length, width, thickness – all based on your style & preference.

Pro Tip: Get help from a surfboard shaper. They know what works best for you.

Selecting the perfect rocker curve

The rocker curve is a key design feature of a surfboard that can make or break your surfing experience. Finding the right balance between speed, maneuverability, and stability is important. Here are some tips:

  • Flatter rocker: Faster and more stable – great for beginners and small waves.
  • Curvier rocker: More maneuverable and better for larger, steeper waves. Sacrifices some speed and stability.
  • Hybrid rocker: Combines features of both flat and curved rockers. Versatile and can handle a range of wave conditions. Good for intermediates and advanced surfers.
  • No one-size-fits-all solution. Experiment with different curves until you find the best one for your style and conditions.

Shaping Your Surfboard blank

Gather the tools and materials needed for shaping your surfboard. This includes:

  • Fiberglass cloth


  1. Decide where to put the fins and leash plug on the bottom of the board.
  2. Use a cutting blade to make holes, being careful not to cut the deck or bottom.
  3. Sand the area around the holes.
  4. Cut a piece of fiberglass cloth to fit over the board and the holes.
  5. Mix resin and catalyst according to the instructions.
  6. Apply it to the board and cloth.
  7. Place the fins and leash plug into the holes and secure with the key and rope.
  8. Wait for the resin to cure before sanding the bottom.

Pro Tip: Regular maintenance of your surfboard, including attaching fins and leash plugs, will extend its life and improve your surfing experience.

Curing and Testing Your Surfboard

Your surfboard is out of the mold – now it’s time to cure it! This is a must. To guarantee your surfboard can handle the waves, you need to cure and test it. This way, you can make sure your board has the strength and qualities you need for a great surfing experience.

Allowing for proper curing time

Curing a surfboard is essential. It’s when resin and hardener chemically react and harden. Here are some tips:

  • Follow the manufacturer’s instructions for mixing correctly.
  • Put the board in a warm, dry place and leave it alone.
  • Check it regularly during the curing process. Keep it away from extreme temperatures and humidity.
  • Do a tap test when the curing time is done.

Pro tip: Patience is key. Allow enough time for a sturdy surfboard.

How to test your board in the water

Before you go surfing on your new board, it’s important to test it in the water. Here’s how:

  1. Choose a calm area with small or no waves.
  2. Wear a leash and fins and paddle out to waist-deep water.
  3. Lie on your board and experience its buoyancy and stability.
  4. Test turning by leaning to the sides and feel how it responds.
  5. Practice catching small waves.
  6. Notice any defects or issues, like roughness, soft spots, or instability.
  7. Return to shore and fix them.

Regular testing of your board can help keep it in good condition and increase performance.

Making adjustments for a better ride.

Tweaking your surfboard can have a huge impact on your surfing experience! You can customize it according to your skill level, wave type, and preferences. This leads to a better ride. Start by inspecting the board’s shape, fins, and rocker.

If too short or narrow, it won’t provide enough buoyancy. If too long or wide, it’ll be hard to control. The fin setup should depend on the conditions and your style. You can also adjust the rocker to get more speed or make it easier to maneuver. Make sure the board’s weight and balance feel comfy to you. Testing it in different conditions can help you decide what needs to be changed for the best experience.

Pro tip: Write down every adjustment you make and how it affects the ride. This’ll help you refine your board to maximize performance.
