Tail Shape
The tail is where your surfboard talks to the wave. Different shapes release energy differently, some hold in, some break free, some do both.
Squash
The all-rounder. Wide enough for drive and speed, with enough curve to release in tight spots. If you don't know what to pick, pick this.
Round
Smooth and connected. Holds into the face more than it releases, long, carving turns with flow. Best in better waves with wall.
Round Pin
The sweet spot between control and flow. Loves powerful, open-face surf where you want to hold speed in the pocket.
Pin
Built for power. Digs in and holds through serious speed, bigger waves, heavier surf. Made for threading barrels and clean lines.
Swallow
Two mini pins. Releases and slides when you need it, while still generating drive. Loose, lively, surfs bigger than it looks. A twin fin's best friend.
Diamond
Middle ground between swallow and squash. A little more tail area without the hard edge. Balanced and versatile.
Bat
Wider than a swallow with a dramatic concave cutout. Generates lots of lift and speed in weak, slow waves.
Square
Blocky and responsive. Lots of tail surface area = drive and quick pivot. Works well on shorter, wider shapes, retro fish vibes.
Wing
Cutouts on the rail ahead of the tail that tighten your turning radius. Often combined with other tail shapes.
Fin Setup
Fins are your steering, your drive, your connection to the wave. The number and type changes everything.
Single
One fin. Clean, flowing. Designed to draw long arcing lines. You steer with your whole body. Best on longboards and mid-lengths.
Twin
Two fins, no center. Loose, drifty, and fast. Skates across the water, great for speed in gutless surf and big open turns.
Twin Keels
Two big, wide-based fins. More drive and hold than standard twins. The engine of a retro fish. Makes small surf feel alive.
Thruster
The standard. Three fins, balanced, predictable, works in any condition. A safe choice that won't surprise you.
Quad
Four fins, no center. Speed and looseness of a twin with more hold. Excels in hollow, fast surf at full throttle.
2+1
Big center fin + two small sides. Dial the feeling from "almost single fin" to "almost thruster" by swapping the center fin size.
5-Fin (Convertible)
Five boxes, use some. Ride as twin, thruster, or quad depending on the day. Maximum flexibility.
Bonzer
Fins and concave channels work together, fast, driving, and connected in a way that's hard to explain until you've felt it.
Fin Box Type
What fins will physically fit in your board. Pick what you already own or prefer.
FCS II
Tool-free tab and slot. Fins click in and out in seconds. Huge range available.
Futures
Single screw, one-piece base. Many say Futures flex more naturally and feel more connected.
Glass-Ons
Fins glassed directly in, permanent. No box, no hardware. Board and fins become one. Purists love them.
US Box
Standard for single fin and 2+1 center fins. Slide the fin forward or back to change the feel.
Rocker
The curve of the board nose to tail when viewed from the side. More curve = more maneuverability. Less curve = more speed and paddle power.
Low / Flat
Fast. Catches waves early, glides through flat sections. Best for small, weak waves. Can feel stiff in hollow surf.
Low-Medium
The sweet spot for everyday surf. Fast enough to generate speed, enough curve to handle some power.
Medium
Balanced. Competent everywhere. A shaper's neutral starting point.
Medium-High
For more critical surfing. Better in hollow, powerful waves. You trade paddle speed for control.
High
For powerful, steep, hollow surf. Best left for good surfers in quality conditions.
Shaper's Call
Tell us how and where you surf, and we'll put the right rocker in. Usually the right choice if you're unsure.
Bottom Contour
Controls how water flows under your board, and water flow = speed, lift, and control.
Flat
Simple and fast. Stable, predictable, great for smaller waves. No drama, just go.
Single Concave
Lifts water up and focuses it out the tail, creating drive and speed. Makes a board feel alive. Works in almost any surf.
Double Concave
Two parallel concaves. Splits water flow to each fin, creating lift and acceleration. More maneuverable than single.
Single → Double
Single concave in front (speed), transitions to double in back (drive). The most common modern combo. Does everything well.
Vee
A slight ridge down the center pushes water to the rails. Makes the board pivot easily rail to rail. Looser turning.
Channel Bottom
Multiple carved grooves. Each channel grips the water and creates directional speed, like fins on the bottom. Fast and driving.
Hull / Belly
Rounded, convex bottom. Creates a smooth, gliding, connected feeling. Classic on old-style single fins.
Spiral Vee
Complex curved vee through the tail. If your shaper recommends this, trust them.
Rails
The edges of the board, the part that cuts into the wave. They determine grip, release, how the board enters turns, and how it handles power.
Boxy / Full
Thick, rounded. Very buoyant and forgiving, great for catching waves early. Found on longboards and fun shapes.
Soft / Rolled
Round and forgiving. Smooth and predictable. Works well for a mellow, flowy feel.
Medium
The all-rounder. Most everyday boards live here.
Pinched
Tapers to a narrow edge. Bites into the wave precisely, releases quickly. Best for experienced surfers.
Hard / Down
Sharp angle at the bottom edge. Maximum bite, maximum release, no forgiveness. Performance shortboards in good surf.
Foiled (thin)
Thinned-out rail profile. Light and fast, sensitive to weight shifts. Best matched to surfers with good technique.
Nose Shape
Affects paddle entry, wave catching, and how forgiving the board is when you're not perfectly positioned.
Pointed / Narrow
Cuts through chop and fits into steep, critical sections. Less early wave-catching, more precision once up.
Medium
Balanced option. Catches waves reasonably early, handles a range of surf. The default.
Round / Full
Wider and rounder. Generates more paddle surface, catches waves earlier. Common on mid-lengths and eggs.
Wide / Blunt
Maximum nose width. Paddles and catches waves exceptionally well. Best on mini-mals and longboards.
Beak
Slightly downturned nose tip. Cuts into the wave face and reduces pearling on steep drops.
Glass Schedule
The fiberglass wrapped around the foam. Determines weight, strength, and flex.
Light (4+4 / 4)
Maximum sensitivity and flex. Lighter, more responsive. Dings more easily. Best for experienced surfers.
Standard (6+4 / 4)
The most common glass job. Survives normal use. A good balance for most surfers.
Heavy (6+6 / 6)
Built to last. Holds up to heavy surf and abuse. Good for step-ups and surfers harder on equipment.
Stringer
The thin strip down the center that gives the board structure and controls flex.
Standard Basswood
Light, consistent, reliable. Most boards are built with this.
Cedar
Warm reddish grain that shows through clear glass jobs. Beautiful, similar flex to standard.
Redwood
Denser and stiffer. Adds rigidity. Often chosen for heavier glass schedules or step-ups.
Triple
Three stringers, adds torsional stiffness. Common on bigger boards. Stiffer, holds integrity in powerful surf.
Stringerless (EPS)
No stringer. Lighter, more even flex nose to tail. Used on EPS/epoxy builds. Snappier, livelier.
Parabolic
Curves out toward the rails through the middle. Even flex across the width. Smoother, more connected feel.
Blank / Foam Type
The core of your surfboard. Affects weight, flex, buoyancy, and overall feel.
PU (Polyurethane)
The classic. Warm, lively flex that most surfers grew up on. Pairs with polyester resin. Slightly heavier but for many that weight is part of the feel.
EPS (Expanded Polystyrene)
Lighter and more buoyant. Stronger and lighter with epoxy resin. Floatier, snappier underfoot. Great for higher-volume boards.
Color / Finish
Where your board becomes yours.
Clear
No tint, natural foam showing through. Clean, classic, timeless. The purist's choice.
Resin Tint
Transparent color mixed into the resin. Deep, rich, glassy. Think golden yellow, ocean blue, coral.
Opaque Color
Solid color, can't see the foam. Bold, graphic statements.
Acid Splash
Wild, organic swirls. No two are the same. The kind of board that turns heads in the parking lot.
Pinlines
Thin lines of color along rails. A classic finishing touch.
