Introducing the FAI 4si
Fai Va’a is proud to unveil our best V1 design to date: the FAI 4si, an outrigger canoe that combines innovation, comfort and performance in a seamless package.
It is the world’s first one-piece monocoque construction autoclave-cured prepreg carbon fiber V1, giving it an unmatched combination of strength and lightness.
For well over a decade, we had been working on refining the design of the successful FAI 3 design during what we called the “FAI 3X” project, which was to become a series of prototypes designed with the end goal of designing the best V1 we could as the FAI 3’s successor and set a new baseline for Va’a Hoe: the FAI 4si. Over these years, this endeavor led us on many trials with countless hours of testing and observations on the water, countless discussions about design with our team paddlers, our construction team, our designer and builder friends at home and abroad. Many different design concepts were tested individually and evaluated in order to pinpoint the impact of each change. Continually bringing modifications, we shaped many prototypes, most of which never made it to the public, always thinking about ergonomics as well as performance, refusing to let the status quo govern design choices.
The FAI 4si capitalizes and builds on everything we have learnt over the years spanning the FAI 3X project, from the first official FAI 3X prototype design in 2011 to the FAI 3Xsi design in late 2019 that made it to production or the many unreleased FAI 3X/KCJ prototypes the team paddlers tested over the years.
As V1’s are used in a multitude of conditions (whether it be downwind, upwind, side wind, flat, surf...), we aimed to optimize the performance in the most challenging conditions for paddlers.
The FAI 4si showcases a refined hull with a new cockpit design, streamlined deck, redesigned snap-in iatos and receiver system, new ama and more.
The cockpit was redesigned from the ground up in order to keep a drier cockpit, improve comfort and provide adjustability.
The volume of the cockpit open to the elements was reduced dramatically, allowing much less water to enter in a huli situation and requiring less energy to move the canoe and less time emptying cockpit when huli’ing. This directly contributed to the paddler’s safety while out in the open ocean.
As requested by many team paddlers, the coaming height was increased slightly to contribute to the paddlers’ connected-to-the-boat feeling as well as keeping a drier cockpit in rough conditions, also allowing paddlers to gun bigger conditions.
Wanting to improve on ergonomics, we wanted to promote adjustability by the paddler so they can improve their performance while providing a new level of comfort that would lessen fatigue.
An adjustable and ergonomic EVA foam seat provides better support while cradling the paddler for enhanced comfort and a feeling of being more connected to the boat for better control. The adjustability of the seat allows each paddler to move their center of gravity forward and backward to fine tune their canoe’s balance and enhance their performance based on their individual stance in the canoe or to adapt to conditions. The EVA foam makes the seat comfortable on long paddles and its material allows paddlers to customize it to their specific needs.
The foot rest can be quickly adjusted based on the paddler’s height, accommodating a wide range of paddlers. This allows paddlers of vastly different heights (like a parent and their child or a different members of a club) to share the same canoe. The foot rest has its own integrated foot pump system, enabling paddlers to bail water out with each stroke taken as the leg drive unconsciously activates the pump.
The deck was completely streamlined for better aerodynamics, removing all protrusions and cavities that might alter fluid pathlines. In order to do so, the iatos, the angles at which they enter the deck and the iato receivers all had to be rethought. No more fiddling with hard to press pins on the boat side: an innovative twist-to-lock system was engineered. You twist the iato to adjust or remove it.
With the help of Kevin CJ’s feedback, the ama was entirely redesigned and streamlined to reduced drag, increase stability, avoid swamping and provide better performance in different conditions. More volume directly where most of the paddler’s weight is loaded provide enhanced buoyancy, stability and performance in big conditions. A more rounded hull decreases surface area and drag. An increased tail rocker provides better release and avoids digging in and dragging. A slightly reduced rocker in the front section allows for better performance in a variety of conditions in order to get an all-around ama design.
The hull was refined and continues to provide adequate buoyancy in the bow and great maneuverability to prevent excessive pearling while easing paddlers from bump to bump without losing momentum. As its predecessors, the cross section aft of the cockpit adopts a slightly more V hull allowing for great performance on the flat while giving great control in the surf. The rocker allows for performance in all conditions and retain the glide Fai Va’a designs are well known for.
The FAI 4si reaches an incredible cruising speed and keeps its glide effortlessly. It is very agile and responsive. This Va’a will impress even the most seasoned V1 paddlers in all water conditions. But make up your own mind and take it for a spin to fully grasp the glide this V1 can provide.

~ 20.4 - 20.7 lbs
FAI 4si pro ~ 8.48 - 8.73 kg
~ 18.7 - 19.2 lbs
The FAI 4si comes in 2 versions: standard and pro.
Both standard and pro versions are built in a one-piece monocoque construction with 100% prepreg carbon fiber cured in autoclave at high temperature and high pressure.

FAI 4si “ When creative freedom and personalization matters most for those seeking a light, strong and fast Va'a“
The 100% prepreg carbon fiber construction layup is ideal for the V1 aficionado, looking for a light, strong and fast Va'a whether for fun sessions on the water or for racing against the best Aito and Va'ahine!
You can customize your FAI 4si with 16 colors for the hull, ama and logos in any combination you’d like. You can add customizations such as a deck/hull split, a colored cockpit, graphics from our catalog or a custom graphic you bring. The FAI 4si comes with fitted dust covers for its hull, ama and iatos.
FAI 4si pro “ When every ounce counts to gain a competitive edge “
The pro construction layup was created for paddlers looking for the best in Va'a construction in order to gain a competitive edge as well as those looking for the lightest V1 possible in order to make carrying and transporting it a breeze.
The FAI 4si pro model is lighter than the standard FAI 4si by an average of ~ 0.77 kg (1.7 lbs).
Most of the weight reduction stems from the paint used and painting process, limiting the amount of paint applied and sanding it down to a thin layer, giving the pro model a distinctive sanded-through look.
To keep the weight low, pro model hulls can only be 5 colors (pro Grey, pro White, pro Green and pro Yellow) and customizations options are limited to coloring the cockpit and logos. The ama can be any color and, unlike the standard model, the iakos can be colored.
The FAI 4si pro comes with thicker, UV resistant fitted acrylic marine canvas covers for its hull, ama and iatos for better protection.
