The Next Generation in Surfboard Construction

The Aviso Technology Platform allows for the identical duplication of a hand crafted surfboard using a proprietary method of manufacturing. The primary elements of the boards include carbon fiber of varying orientations, specialized high density foam, and epoxy resins. The boards are completely hollow. A High Temperature Fiber Placement Process allows the boards to be some of the lightest and strongest boards ever designed and produced. Nothing ties the top and bottom components of the boards together except for the rails. This enables the deck and bottom to work and flex independently. This unique feature acts as a suspension system to launch the surfer from one turn into the next with remarkable control and momentum.

Since the deck is not directly connected to the bottom, the deck absorbs and stores potential energy and kinetically propels the surfer swiftly and efficiently, allowing an almost constant state of acceleration to be realized by the rider. The flex characteristics of the boards are significantly positive and confer independent flex dynamics. Carbon fiber has remarkable flex memory with a ideal “coefficient of restoration”, a property inherent in any rigid structure that allows it to return to its original state after a physical force is applied (How much a material flexes & how fast it flexes back). Analogies in sports include the technological transition from wood to carbon graphite tennis rackets and bike forks from aluminum to carbon fiber.

Aviso obtains highly tuned master designs from shapers for the creation of their surfboards. As of June 2007, Aviso had alliances with 14 separate shapers, offering over 40 different surfboard designs. On average Aviso has increased the number of different surfboard designs by 2 boards each month and has consistently extended their list of shapers every year.

Materials used in the construction of Aviso surfboards:

The three predominant materials used in the construction of an Aviso surfboard are the following:

  • Carbon fiber of varying orientations
  • High density, closed cell foam
  • Epoxy resins

Cross Section

The materials are coupled together and fused in a proprietary tooling process that provides an elevated temperature and pressure environment for proper curing of the materials.

Carbon fiber is used because it has a number of characteristics that make it ideal for the construction of a surfboard:

  • Lightweight
  • High tensile and load bearing strength based on orientation of fiber
  • Remarkable refl0ex memory, ideal coefficient of restoration
  • Extremely low flex fatigue over time
  • Carbon fiber is non flammable and stable in the environment.

High density closed foam is used for a number of reasons including:

  • Compression ding resistance, up to 3-4 x polyurethane
  • Waterproof
  • Compatible with epoxy resins
  • Process does not include sanding, negligible VOC, environmentally sound

Epoxy based resins are used for the following reasons:

  • High strength to weight ratio, Stronger and lighter vs. polyester
  • Overall superior material properties
  • Environmentally more sound vs. polyester resins, low VOC

Benefits to the Surfer

  • Favorable Flex Dynamics
  • Carbon Recoil Creates Momentum, Drive, & Maneuverability
  • Natural Buoyancy Characteristics, not corky
  • Strength & Durability (2.5 X standard)
  • Lightweight but Stable in Big Surf
  • 14 World Class Shapers—Over 40 Shapes
  • Swift, powerful surfing

The Ride:
The surfer must allow time to adjust to the percussive nature of a core-less board– this requires more psychological adaptation than actual physical responses to how one rides the board. An Aviso board will allow the rider to properly surf in a more rail-to-rail fashion, allowing the surfer to capture what flex and recoil is translating into drive. The construction of Aviso’s surfboards allows for projection through turns and transitions with speed and efficiency.

Differentiating factors of Aviso’s Surfboards:

Q&A — Common Misconceptions

Will water damage an Aviso?

No.   Every aspect of Aviso construction makes it resistant to any type of water damage, both inside and outside the board and if the board suffers a ding.

Do Aviso’s have different buoyancy characteristics vs. foam boards?
No.   Buoyancy is an issue of weight and volume. An Aviso will have the same buoyant force as a PU board of similar shape and dimensions under a surfer of similar weight.

Will an Aviso sink if it fills up with water?
No.   It is physically impossible to sink an Aviso. If it fills up with water due to a large ding the board will still float. Therefore an Aviso will not drag a surfer underwater if water gets inside the board. The board may be sluggish, but can be ridden sideways, top up, on the surfers belly to the beach.

Does Aviso technology only apply well to fishes?
No.   Aviso boards, in all board size and shape categories, possess remarkable flex qualities, handling characteristics, and strength. From the 5’1’’ shortboard to the Dale Velzy 9’6’’, Aviso boards provide a more performance driven experience that extend life to a quiver.

The professional surfers are not convinced of Aviso?
No.   Professional surfers providing positive feedback on our boards include, but are not limited to, the following;   Chris Ward, Pat O’Connell, Tom Carroll, Dave Rastovich, Shea Lopez, Tamyo Perry, Dustin Barca, Christian Wach, Christian Fletcher, Shayne McIntyre, Beau Young, Jesse Heilman, Punker Pat Towersey, Ryan Carlson, CJ Nelson, and a plethora of other rippers. This list is rapidly growing.

Are the materials and methods used in the construction of Aviso boards bad for the environment?
No.   Both the materials and manufacturing practices of Aviso are far more environmentally sound vs. traditional board building. Low volatile organic content output (VOC) and epoxy is much more environmentally healthy vs. polyester.

Terms & Definitions — Aviso Surfboard Properties

Polar Moment of Inertia (PMI) — The “Pendulum Effect” Aviso has a lower PMI which results in a board that responds faster to the rider’s control.

Moment of Inertia (MOI) — Distribution of material in a section which is adjustable by design, Aviso does NOT change over time and use like normal boards.

Coefficient of Restoration (COR) — How fast a structure springs (or snaps) back to its original shape. Aviso has a High COR, which produces more acceleration out of turns. Regular boards are low COR. Aviso’s dynamic flex and recoil, propels surfer through turns and dead spots in a wave.

Modulus The rate of stretch or compression in a material from a load

Carbon Fiber is 34-35 million psi vs. E-glass stiffness is 10 million psi
It takes about 1/3 the amount of Carbon to produce the same Flex as Glass.
The higher carbon content increases ding resistance.

Density — The Weight per cubic inch of a material. Carbon is 2/3 the density of Glass

Fiber Orientation Aviso uses a “High Temp Fiber Placement Process” to put the load carrying fibers in any directions and quantities required to achieve “the desired performance”. This means Aviso can create a wide variety of board performance out of any given shape.

Flex Characteristics — The unique Aviso process and material flexibility allows the flex characteristics of the board to be optimized for each shaper.

Aviso can quantify performance using FEA for values, foam & skin.

Aviso surfboards perform nearly the same as when new over the life of the board. Poly boards never stay the same after the first weeks-month of ride.
