The outline is the overall shape from nose, mid through to the tail. The outline directly changes the performance, controlling how the board glides and reacts to the water. A board’s outline can change significantly in width and length dependent on the style of riding. A long board generally provides better glide, a shorter board delivers more maneuverability and a wider board gives improved balance. As the water flows around the outline, the nose shape will enhance speed and reactivity, while tail shape creates maneuverability and release.


Provides stability from wide nose and tail and is generally suited to smaller less hollow waves.


Narrower nose and tail for speed and control to fit in tighter pockets on larger hollow waves.


Longer straighter shape extends the waterline throughout the length of board for increased speed down the line .


Follows a continuous curve from nose to tail for tighter turning.


Combines a curved nose to guide through turns, parallel rails in the mid section for speed down the line and a pulled in tail for tight pivotal turns.


Combines a shorter narrower tail outline for greater turning with a fuller long board nose for stability. The nut outline curve accelerates water flow for fast acceleration and speed on wave.


The bottom shape dictates how the water flows under the hull from nose to tail, influencing glide, lift and rail-to-rail turning. Different style boards will mix a variety of bottom configurations to enhance the performance whether its cruising, surfing, or racing.


Planes on top of the water to generate speed but limited in maneuverability. Generally combined with a concave to add speed and are suited to smaller conditions and heavier riders.


Generates lift, drive and speed as it channels the water from nose to tail. Suited to large cleaner conditions.


Splits the water into 2 channels for a looser ride with flowing maneuvers. Normally combined with a single through to a double.


Lowest point provides a pivot point for easy rail-to-rail turning.
Normally positioned from the mid point on bigger boards through to the tail on smaller boards.


Creates a very flat rocker in the centerline of the board allowing water to flow effortlessly in a linear direction for
optimum speed, The outer planes of the board away from the channel, benefits from a more generous rocker allowing the board to be controlled in the wave. Center channel also provides extra stability by placing most buoyant area away from center line (Catamaran effect).


The rail of the board controls how the board turns and performs in the water. The speed of the board will influence the rail shapes and the amount of grip, drag and release required. Combinations of different rail shapes are used from the tail, midpoint and nose and dependent the type of outline shape.


• Used at the tail of boards to create a sharp edge for water to flow off quickly to create speed.
• Combining a sharp bottom shape with thinner rails delivers more responsive and reactive performance, with more control and grip to turn the board when wave riding.
• Used in Race and performance surf sup.


• Round rails are smooth and allows water to wrap around
the rail for grip but are generally slower in speed.
• Round rails are normally used in the mid section and therefore thicker in profile.
• Round rails are more forgiving and provide grip when entering turns.
• A round rail struggles to hold an edge in steeper waves.
• Used in all round and larger surf sups.

60/40 RAILS

• Semi sharp rails that are forgiving yet responsive in performance.
• Used in the mid section to the nose.


• Provides two tuck lines for greater stability so you can ride a narrower board and have increased control to turn direction in the surf.
• The Chamfer rail boosts acceleration and speed as it funnels the water creating a clean release with less drag from the water wrapping around the rail.
• Used on Touring, Freeride, All Star and Sprint.


Tail shapes control how the water releases from the bottom shape and around the outline. The tail Is one of the most critical parts of a SUP as it is the pivot point for surfing.


Narrow width increases water flow for a smooth release, delivering improved tracking and directional control at high speeds from the reduced surface area. Typically used for Gun style boards that require control and speed on big hollow waves.


Wider tail shape increases the surface area providing more lift for looser and easier drawn out turning. No hard edges make it ideal for rail-to-rail surfing and versatile both steep and softer wave conditions.


A popular and versatile shape for high performance surfing, the added width provides more lift and helps maintain speed at slower spots on wave. Rounded corners give bite and squaretail makes it very responsive for sharp pivotal turns.


Wide tail maintains speed and generally suited to softer smaller playful wave with a loose performance to slide the tail.


Wide and stable with less curve in rails and sharper edges for increased ability to make pivotal and vertical projections.


Combines the reactivity and moderate volume of a squash tail with the control and speed of a pintail.


is the amount of curve from the nose to the tail of the board. A board’s rocker will change dependent on the style of board, for example a longer board generally has a flatter rocker to maximize glide, while shorter boards generally have more curve for surfing and maneuverability.


A flatter and straighter rocker maximizes the board’s waterline increasing glide and speed with every stroke. A flatter rocker is suited to cruising, touring and racing boards, as they require fast overall speed. Most boards will still have moderate amount of nose kick at the tip of the board to handle small waves and light chop.


A curved rocker reduces the waterline slightly minimizing overall glide but increases the maneuverability of the board. A curved rocker is used in the surf and downwind racing to allow the board to catch and ride waves without the nose-diving. Curved rockers will normally have tail and nose kick for trim control when turning and wave riding.
