Firewire Taylor Jensen TJ Twinzer Helium 7'2 × 21 ⅞ × 2 15/16 Surfboard

Meet the Taylor Jensen Twinzer, a collaboration between Stu Kenson & Taylor Jensen. An iteration on the iconic design from the San Diegan shaper: this is the Thruster, enhanced. Better transitions and more turns in this iconic design.

"I started making Twinzers right after seeing Martin Potter ride one in 1989 at Lower Trestles.

Back then, Twins were known to offer more speed and more maneuverability than single fins. These Twins were the foundation for what became Simon Anderson's Thruster. When I watched Martin Potter on a Twinzer that day at Lower Trestles, it was clear to me that a Twinzer setup had potential to become a solid innovation to a Thruster set.

About 10 to 12 years ago, I made some design changes to the designs I originally refined in the early 90s, such as updated fin placements, and minor changes through the overall shape of the board.

This R&D turned into a game changer. From fishes to eggs, up into mid-lengths and performance longboards, and now making them into step up big wave boards.

One of the other key things about the Twinzer is how well it works in a variety of surf conditions from small junk surf to well overhead powerful surf.

And...they work just as well on your backhand as they do on your forehand." —Stu Kenson

Wave Type

The Taylor Jensen Twinzer works well in surf 2 to 7 foot, in a variety of conditions.

Board Features

An innovation inspired by the performance of Thrusters and the desire to make them more fun, functional, and finessed underfoot.

Helium Core Technology

This is Firewire's best-selling technology, with a new updated look. A stringerless EPS core with flex controlled at the rails made from Paulownia and Balsa wood and our proprietary deckskins - this construction is light and lively underfoot, and excellent at generating speed in everyday waves. Rob Machado calls the parabolic flex control provided by the wooden rails in the Machadocado. Good for drive on rail and control in critical sections.

Helium 2.0 uses 0.8 lbs light weight Expanded Polystyrene (EPS) core with closed-cell waterproof structure skins, combined with high-density (PAULOWNIA) parabolic rail inserts, Polonia wood nose and tail blocks, and high-density fin box inserts. All inserts and components are bonded using expanding epoxy resin to form an airtight composite structure. The result is a lightweight, flex-tuned, waterproof, and impact-resistant blank.

Traditional PU boards use a single polyurethane blank with a central wood stringer. They rely on heavier foam and fiberglass for strength, resulting in more weight, lower flex control, and increased water absorption when damaged.

Helium Technology Core Construction

Helium blanks move through a multi-stage, precision-controlled build process designed to ensure consistency, strength, and tuned flex behavior:

1. Outline cutting and high-density component insertion
2. Deck cutting and deck skin application
3. Bottom cutting and bottom skin application
4. Final rail cutting followed by hand-shaped rail tuning

Helium utilizes a vacuum-laminated sandwich construction, featuring a 2.4 oz. fiberglass layer positioned between the EPS (Expanded Polystyrene) core and proprietary MPP (Modified Polypropylene) composite skins, followed by an external 4 oz fiberglass lamination on both the deck and bottom. The vacuum lamination process ensures uniform adhesion, reduced resin weight, and superior structural integrity across the entire board.

High-density fin box inserts are integrated during construction to reinforce fin attachment points and minimize the risk of cracking or flex distortion under load.

During lamination, the parabolic rail structure is locked into place under vacume, creating stored elastic energy within the blank. This “loaded spring” effect allows the board to actively return energy during turns, increasing projection and speed—particularly in small to medium surf—while requiring less physical input from the surfer.

Helium Technology Materials

Helium is approximately 25–30% lighter than PU boards, with a more responsive flex feel, waterproof EPS core, and lower VOC emissions thanks to epoxy bio-resins. It has a 3–5+ year lifespan and keeps boards out of landfills longer. Traditional PU boards are heavier, less flexible, and last only 1–2 years on average, with higher environmental impact.

Freshwater Performance & Buoyancy

EPS foam performs better in freshwater wave pools due to its higher relative gravity profile, which provides superior buoyancy. EPS/epoxy boards deliver approximately 2–3% more net flotation than PU boards of the same volume in freshwater, where reduced water density affects board lift.

Example estimates (freshwater, same volume):

• 30 L board: EPS +2.2% lift advantage (~0.6 kg)
• 35 L board: EPS +2.2% lift advantage (~0.7 kg)

Helium Technology Key Tech

• EPS (Expanded Polystyrene): Closed-cell foam that’s lightweight, waterproof, and recyclable — forms Helium’s core.
• MPP Composite Skins: High-density sandwich composite skins for dent resistance and flex control.
• 2.4 oz. e-Fiberglass (Internal Layer): Light fiberglass layer that distributes load evenly between core and skins.
• 4 oz. e-Fiberglass (Outer Lamination): Outer laminate providing durable finish and surface protection.
• HD Polonia Wooden Rail Inserts: High-density foam strips enhancing flex control and preventing rail cracking.
• High-Density Fin Box Inserts: Dense composite blocks integrated into the core to anchor fin boxes securely.
• Paulownia Wood Blocks: Light hardwood reinforcements for nose and tail strength.
• Epoxy Bio-Resin (Entropy): Bio-based epoxy resin system with superior strength and flexibility.

Helium Tech Summary

Helium Technology delivers an ultra-light, lively ride with a distinct sense of stored energy and rebound. Built around an EPS core and high density of Paulownia Wooden parabolic rail. Helium boards retain inherent kinetic energy in the rails, allowing for loaded spring-back out of turns and smooth projective flex. This gives surfers a sensation of speed, flow, and effortless projection.
