Everything you need to know about surfboard design and performance by our shop.


You don't have to be a surfboard shaper to be an accomplished surfer, but information and knowledge are never too much. In this particular case - surfboard science, surfboard art - you might make the difference if you add up awareness and comprehension to your physical and natural water skills.

A surfboard is a hub between water, waves and people. A surfboard without a surfer is nothing. A surfer without a surfboard is never a surfer.

To understand better how surfboards work, we have to learn about the forces that act on them, the variables of , the general construction types and techniques, the core materials, and the types of surfboards.

For a more in-depth look at what's inside a surfboard, get "The Surfboard Book," a fundamental perspective on design, shaping and performance by Simon Anderson, Dick Brewer, Steve Lis, Bob McTavish and more. These are a few rules of thumb that you will find useful when buying a new board or when picking one from your quiver:


1. More buoyancy means easier paddling above water;
2. The more area of the surfboard is in contact with the water, the more friction drag will exist and, the slower the surfboard will be;
3. The greater the rocker, the greater the drag force;
4. The greater the velocity or speed, the greater the lift;
5. Bottom shapes with concaves and channels produce an upward force or lift;
6. Wave faces flow and move in orbital fashion and create lift;


1. More surfboard area means more planing potential, less sinking and bogging;
2. The elements of a template are total and half length, nose shape and width, outline curve, location of the wide point relative to the center, width, tail shape and width;
3. More curve in the outline means easier turning;
4. Longer boards provide faster paddling, greater risk of nose diving and more effort required in turning;
5. Wider surfboards plane better in dead or slow wave spots;
6. Wider boards turn easier at slow speeds but have poorer rail-to-rail transitions;
7. Wider templates have poor hold in the wave face at high speeds on rail;
8. Wider surfboards are stiffer;
9. Rounder noses provide more lift and buoyancy, but create form drag;
10. Pointed noses suffer less "baseball bat effect" and are easier to hold in rail turns;
11. Pin tail surfboards have extremely low surface area and high holding power;
12. Square tail surfboards have high planing area and looseness;
13. Thicker boards have greater buoyancy and have easier paddling;
14. More thickness in the middle of the board means difficulty to lean on rail;
15. Thicker tails are looser at slow speeds;
16. More rocker means easier turning, harder paddling, and slow speeds in a straight line;
17. More rocker means less nose diving;
18. Vee bottoms create less lift and are slower than flat bottoms in neutral position;
19. Vee bottoms allow for easier rail-to-rail transitions;
20. Single concaves create more lift and speed and are harder to turn;
21. Double concaves keep the rails free and are looser and faster;
22. Harder rails plane very well but have a stiff, less smooth response to turning;
23. Soft rails are slower but provide better hold in subtle turns;
24. Tucked under edge rails balance the characteristics of hard rails and soft rails;
25. Greater fin area means better holding power;
26. Streamlined fin foils have higher holding power;
27. Asymmetrical side fin foils provide better directional holding power;
28. Greater fin base length/rake resists lateral turning;
29. Greater fin height creates greater resistance to rail-to-rail turning;
30. Further forward fin placement will loosen up the board;
31. Further back fin placement will create more holding power and drive;
32. More space between the front and rear fins means more torque required for weaving;
33. Toed-in fins create more drag and are easier to turn;
34. Bigger fin cant/camber means looser turns;


1. Traditional construction includes solid timber and hollow wood. They are strong, but they are heavy;
2. Sandwich construction puts strength only where it is needed, and offers high strength relative to weight;
3. Conventional manufacturing is all about moulding a foam blank from polyurethane beads, hand shaping the pre-moulded foam blank, and applying fibreglass and resin by squeegee;
4. Shaping machines cut foam to a predetermined shape designed in a computer software;


1. More weight means more force needed to accelerate and turn;
2. Greater density cores add more strength but are less flexible;
3. Foam core is roughly half the weight of a surfboard;
4. Balsa is five times heavier than foam;
5. Doubling core stiffness is doubling the strength, but the flex remains the same;
6. Increasing foam core density means increasing strength and weight;
7. Carbon fiber is two times stiffer, two times stronger, and only 1.1 heavier than glass;
8. S-glass and E-glass are three times more flexible than carbon fiber;
9. Extra layers of glass can triple the load capacity of a board;
10. Choosing epoxy over polyester resin has negligible impact on strength, stiffness, weight, but epoxy is more impact resistant;


1. Longboards offer easy paddling and wave catching, and stability, but are harder to turn;
2. Shortboards require more effort to paddle, but they trim and turn without having to move feet;
3. Fish boards plane well, side-slip on steep fast waves and can keep the speed over slow sections;
4. Twin fin surfboards have less fin drag than a thruster on rail, are relatively easy to turn on medium waves, but tend to side-slip on waves of consequence;
5. Thruster boards have more drive and hold than a twin fin, are looser than a single fin but manage to perform well on bigger vertical waves;
6. Quads have less fin drag than a thruster on rail, offer a stiffer rotation comparing to a twin fin, but won't side-slip on bigger waves;
7. Guns are easy to paddle for catching big waves, and they're not easy to turn, but hold the wave face in steeper drops;
8. Tow-in surfboards are short, narrow and heavy, and come equipped with small thruster/quad setups designed to reduce drag;7
