Class / Specialty Boards

Retro boards / Specialty Boards /

Description and Range of Conditions: Retro boards are shortboard designs from the 60s, 70s, and 80s for the whole spectrum of surf conditions. The seductive feeling of a surfboard gliding like a pelican on the updraft of a moving wave risks being lost in some lower volume designs. Shortboards from the late 60s to the late 80s maintained the glide / trim component of the longboards that proceeded them. Retro boards feature low rocker profiles, fuller outlines, mellow bottom contours, and a complete variety of fin configurations.

Rocker: Low with some variation by the design.
Profile or Foil: Moderate foils. Various decks depending on the design.
Outline: Fuller than most contemporary shortboards.
Bottom Contours:Varies by the design - convex and concave.
Rails: Varies by the design.
Fins: Single fins, 2 x 1s, Twin fins, Bonzers, Thrusters, and Quads.


Single fins / Specialty Boards /

Description and Range of Conditions: Surfboards during the first to decades of the shortboard revolution / evolution (with the exception of the development of the Fish in the 70s and Twin fins in the 80s) were single fins. Rockers, profiles, and outlines varied by the design, but they all had one fin. Employing contemporary rockers, profiles, outlines, bottom contours, and rails – adjusting them for various conditions and a single fin – yields a "bitchn" Specialty Board.

Rocker: Varies by the design.
Profile or Foil: Various foils and decks depending on the design.
Outline: Varies by the design.
Bottom Contours: Varies by the design - convex or concave.
Rails: Varies by the design.
Fins: Single fins.


Twin fins / Specialty Boards /

Description and Range of Conditions: Designed for knee high to overhead waves in all conditions. Twin fins first developed in the late 60s, but were somewhat overlooked until Mark Richards embraced the design in the late 70s and early 80s. The narrow tails of single fins could limit performance with their lack of surface area. The extra tail width of the twin fin offered more surface area and flotation, and the twin fin configuration produced a fast loose and responsive surfboard. Twin fin design is a combination of rocker, outline, tail shape, fin positioning, and fin shape.

Rocker: Low entry, speed box, and low tail rocker.
Profile or Foil: Moderate foil. Crown, flat deck, or concave deck.
Outline: Balanced with slightly full nose and tail. Swallow tail.
Bottom Contours: Tri plane to vee or single to double concave to vee.
Rails: Moderate crown.
Fins: Twin fin.


XX Volume Grovelers / Specialty Boards / NC "Malolos" & "Abalones"

Description and Range of Conditions: Designed for flat to overhead waves in marginal to good conditions. XX Volume Grovelers are extremely high volume surfboards. The lower volume of contemporary shortboards can limit performance in tiny gutless waves with the exception of world class professional surfers. The substantial extra width and volume of XX Volume Grovelers produces a great paddling, wave catching, fast, and responsive surfboard.

Rocker: Low entry, speed box, and low tail rocker.
Profile or Foil: Moderate foil. Crown, flat deck, or concave deck.
Outline: Balanced with full nose and tail. Squash, Thumb, Round pin, and Swallow.
Bottom Contours: Single to dominant double concave with peak of double concave under the surfer’s stance or dominant single to double concave in fin array with single concave under the surfer’s stance.
Rails: Moderately full.
Fins: Thruster or quad.


Bonzers / Specialty Boards / NC "Bitchn Board"

Description and Range of Conditions: Designed for knee high to overhead waves in all conditions. The Bonzer was pioneered and developed by Duncan and Malcom Campbell beginning in 1969 - 70 in response to their perception of the limitations of speed and control of early shortboards particularly in powerful surf. The key elements of their design are the “triangular” multi fin array and the single to double concave bottom with moderate to deep "channels" running parallel to the keel fins. The Bonzer fin configuration and bottom contours can be applied to most surfboard designs.

Rocker: Relaxed entry, speed box, and moderate tail rocker.
Profile or Foil: Moderate foil. Crown deck.
Outline: Balanced shortboard outlines. Squash, Thumb, Round pin, and Swallow.
Bottom Contours: Single to dominant double concave with peak of double concave under the surfer’s stance or dominant single to double concave with single concave under the surfer’s stance. Two or four channels (depending on the number of keel fins) running parallel to the keel fins.
Rails: Crowned.
Fins: Two or four "Keel" Bonzer fins plus 6 ½" single fin.


Class / SUPs

SUP Flat Water /

Description and Range of Conditions: Designed for cruising, speeding, or racing in open ocean, bays, rivers, lakes, - basically any open body of water. Flat Water designs are high volume SUPs with length, width, and thickness maximized. They are designed to plane with minimum drag. There are variations of Flat Water SUP designs depending on rider experience and water conditions.

Rocker: Relaxed rocker throughout.
Profile or Foil: Moderate foil. Crown deck, flat deck, or concave deck.
Outline: Balanced with maximum surface area for all around boards. Narrower overall with pulled in nose for "speed" or "racing" boards. Squash, Thumb, or Round pin.
Bottom Contours: Tri plane to panel vee.
Rails: Full.
Fins: Single fin or 2 x 1.


SUP Wave /

Description and Range of Conditions: Designed for knee high to triple overhead waves in all conditions. SUP Wave designs vary depending on rider experience, fitness, and skill and the venue, size, and type of waves. Small wave boards resemble somewhat longer and notably wider Longboards or Eggs. SUP wave boards for overhead to triple overhead waves resemble shortboard designs for the equivalent size waves.

Rocker: Relaxed rocker throughout for smaller surf. Extended shortboard rockers for head high to triple overhead surf.
Profile or Foil: Moderate foil. Crown deck or flat deck.
Outline: Balanced with maximum surface area for small surf. Narrower overall with pulled in nose and tail for larger surf. Squash, Thumb, or Round pin.
Bottom Contours: Tri plane to panel vee or tri plane to spiral vee.
Rails: Full.
Fins: 2 x 1, Thruster, or Quad.


Class / Foil Boards

Prone Foil Boards / Foil Boards /

Description and Range of Conditions: Designed for knee high to overhead waves in all conditions. Prone Foil Boards are designed to perform two primary function: paddle extremely well for it's length and perform as an integrated part of the foil system once out of the water. Paddling is essential for catching waves and paddling back to the take-off area of the lineup. Maximizing surface area and volume provides paddle power. The bottom rocker, deck rocker, and profile are designed to run in a parallel plane with the foil's "fuselage" thus integrating the board into the foil system. The surface geometry of a Prone Foil Board is designed as a "wing" with balanced lift to add speed and control.

Rocker: Extremely low nose to tail. Rocker at the foil is perpendicular to the foil’s mast or parallel to the fuselage.
Profile or Foil: Notably full nose to tail. Concave deck.
Outline: Full and notably straight with maximum surface area. Squash, or Thumb.
Bottom Contours: Tri plane to panel vee.
Foil System: Track Boxes.


SUP Foil Boards / Foil Boards /

Description and Range of Conditions: Designed for ankle high to overhead waves in all conditions. SUP Foil Boards are very short for an SUP. They are designed to catch waves and perform as an integrated part of the foil system once out of the water. Paddling is essential for catching waves and paddling back to the take-off area of the lineup. Maximizing surface area and volume provides paddle power. The bottom rocker, deck rocker, and profile are designed to run in a parallel plane with the foil's "fuselage" thus integrating the board into the foil system. The surface geometry of an SUP Foil Board is designed as a "wing" with balanced lift to add speed and control.

Rocker: Extremely low nose to tail. Rocker at the foil is perpendicular to the foil's mast or parallel to the fuselage.
Profile or Foil: Notably full nose to tail. Flat deck or Concave deck.
Outline: Full and notably straight with maximum surface area. Squash, or Thumb.
Bottom Contours: Tri plane to panel vee.
Foil System: Track Boxes.
