⚡️ Quick Tips and Facts About Advanced Surfboard Construction

  • Weight matters: a 5 lb EPS blank can knock almost 10% off swing-weight vs. PU, but PU still gives that classic “wet” flex feel.
  • Epoxy ≠ stronger in every way: it’s tougher to ding, but polyester resin snaps back faster, so high-pro surfers often stay PU.
  • Carbon ≠ always faster: too much carbon can choke torsional twist—great for airs, bad for cutbacks.
  • Stringer-less EPS + carbon parabolic rails = the current “holy-grail” combo for small-wave aerial boards.
  • Vent plugs aren’t just for show—boards left in a hot car can build 3–4 psi internal pressure; a simple GOREÂŽ vent saves delams.
  • Sustainability is real: Marko Foam’s recycled EPS blanks cut CO₂ by 40% vs. virgin EPS.
  • 3D-printed fins (like Honeycomb Core by Futures) can shave 14 g per fin—noticeable when you’re pumping down the line.

Pro-tip from our test team: if you’re ordering custom, ask for “sandwich-deck, carbon tail patch, EPS core, epoxy lam”—you’ll get the light weight of EPS, dent-resistance of sandwich, and snap-back of carbon.

🧠 Understanding the Core: Foam Types and Innovations


Video: How to Surf | Top 15 Tips for Intermediate Surfers | Improve your Technique.








Polyurethane (PU) – The “Classic Coke” of Foam

  • Density: ~2.5 lb/ftÂł
  • Feel: Damp, familiar, “surfy”
  • Downside: Brown-outs (yellowing) and heavier than EPS
  • Best for: Shoulder-high to OH waves where feedback > buoyancy

Expanded Polystyrene (EPS) – The Lightweight Rebel

  • Density: 1–1.5 lb/ftÂł
  • Buoyancy: ~25% more float than PU = easier paddle
  • Downside: Spongy feel unless stringer or carbon is added
  • Pro move: Ask for fusion-grade EPS (Marko, Arctic) to avoid the “coffee-cup crumble” when you ding it.

Extruded Polystyrene (XPS) – The Dark Horse

  • Closed-cell = virtually no water absorption
  • But it delams easier because it off-gasses; most factories dropped it.
  • Exception: French winter slabs—XPS + epoxy survives ice-cream headaches.

Emerging Cores You’ll Brag About

Bottom line: PU for feel, EPS for float, recycled EPS for eco bragging rights. Match the core to your local waves and sleep better at night.

🛡️ The Shell: Fiberglass, Resin Lamination, and Protective Coatings

Think of the shell as your board’s immune system. Skimp here and you’ll be nursing dings instead of surfing.

Fiberglass Weights Decoded

Weight (oz) Layers Typical Use Vibe
4 + 4 Standard shortboard Balanced
6 + 4 Step-up Bullet-proof-ish
S-Glass upgrade +20% tensile strength Crisper snap
Vectorply Biaxial Carbon infused Torsional rigidity for big carves

Lamination Schedule Cheat-Sheet

  • Performance shortboard: 4 + 4 oz deck, 4 oz bottom, epoxy over EPS.
  • Daily driver: 4 + 6 oz deck, 4 oz bottom, carbon tail strip.
  • Big-wave gun: 6 + 8 + 8 oz deck, 6 oz bottom, double stringer, vacuum bagged.

Hot-coat vs. Gloss: Hot-coat = functional, sanded finish. Gloss = shiny Instagram model but adds ~200 g.

🔬 Resin Revolution: Epoxy vs. Polyester and Bio-Resins

Polyester Resin – Fast, Familiar, Fragrant

  • Cures tacky-surface → needs wax additive.
  • Smells like 1975 (styrene).
  • Shrinkage pulls tighter to foam = crisp rails.
  • Brittle compared to epoxy.

Epoxy – The Modern Workhorse

  • Tensile strength up to 3× polyester.
  • No stink—great for garage builders with nosy neighbors.
  • Longer pot-life = more time to finesse laps.
  • Downside: yellows under UV unless you add UV stabilizers.

Bio-Resins – Hug a Tree While You Shred

  • Entropy Resins SuperSap replaces 38% petroleum carbon with plant-based.
  • Performance delta: virtually nil; cost delta: +15%.
  • Certified “ECOBOARD” by Sustainable Surf if ≥25% bio-content.

Which to pick?
PU blank → polyester for classic snap.
EPS blank → epoxy (polyester melts EPS).
Eco-project → SuperSap or Wessex Resins Eco.
