To those close to the foiling community, it may seem we’ve entered the
mainstream, but I believe that the sport is just getting started. We’re
finally starting to see small groups of surfers adopt the foil for their
small wave needs. In wind sports, wing foiling is officially taking over.
Kitesurfers are making a complete move, and windsurfers who haven’t
contemplated rigging a sail in the last 20 years are now coming out of
retirement to start winging on a foil board. In the world of electric, more
and more eFoils are starting to pop up in the wild and as houseboat
owners cruise around with multiple outdated jet skis on the aft deck,
they ask themselves, “Why don’t we have one of those?” The first
person foiling was a kook, when it was two people they were weird,
and now, with gangs of foilers at local breaks and WhatsApp groups
excitedly messaging each other about one-foot surf, we have ourselves
a movement. If you look closely at the strange trends, you can start to
visualize the evolution of a new sport with multiple segments.
I see two advancement trends in foiling. The first is the early advocates,
the ones who have been on the edge of the sport for years, who are
going to achieve levels of mastery that are simply beyond what we can
even comprehend today. I see it now with riders we work with at Lift.
Some are only a few years into foiling, some are still in high school,
but they’re doing flips and tackling waves that seemed insurmountable
to pioneers just a year ago. I firmly believe these riders are going to
be flying out of barrels, riding huge waves at incredible speeds, and
doing acrobatics similar to what we see in the world of snowboarding.
Have a look at what people achieve behind a boat on an Air Chair and
then combine that with fearless young surfers on large waves, light
equipment, and foot straps. These young guns may even adopt an eFoil
as the tool needed to get them launched into such surf...
The second is that we’re going to see the infrastructure building quickly
for further mainstream adoption, education, and enablement of new
riders in all types of foiling. This is going to mean more brands jumping
into the sport, more schools and lesson opportunities, and an increased
desire from people of all skill levels to try foiling. The multiple branches

A NOTE FROM LIFT FOILS FOUNDER
of foiling—surf, SUP, wake, kite, wingdings, eFoils—are what will create so
much attention and what will offer an avenue for everyone. We’ve signed
up hundreds of schools and rental areas to represent and showcase Lift
eFoils in the last two years alone, and that speaks to the excitement
that’s going to continue across all areas of the sport.
Foil designs and equipment will continue to evolve. Wing designs will
start to be refined for more specific applications. Just as you have
different surfboards for different kinds of surfing, the same is true
of hydrofoil designs. I think the most exciting will be the adoption of
smaller wings as foilers discover an incredible amount of speed and
maneuverability in more powerful surf. Glider wings will allow for the
endless riding of small waves and the ability to tap into open ocean
swells and chop. It will no longer be people riding at specific breaks but
instead riding their entire coastline...
Winging will allow for a new wave of excitement in the world of sailing
as new people take an interest once again in the ancient art of riding
the wind. What’s most exciting is that “non-surfers” will learn to wing
foil and surf open ocean swells in a matter of a few lessons—something
that traditional surfers have never dreamed of. Skilled sailers will create
rigid wings (true foils) that allow them to reach new speeds and a whole
new category of racing. The world of electric foiling is endless and new
crafts will appear that will excite just about everyone. The combination
of tech and tradition will soon meld into new levels of the sport. Just wait
and see what we have in store for you.
At the end of the day, it’s no longer a question of whether or not foiling
will become a mainstream sport; we’re past that phase. It’s a question
of how far we can take it. I have so many ideas flowing that as
soon as I finish one new design, I’m seeing three more in front of it. The
potential is crazy, and as the community continues to expand, everyone
will contribute more and more to the development of the sport. That’s
the most exciting part of it all: community, and finding new levels of
stoke with your peers, and sharing new ideas that shape the next level
of surfing for everyone.

3. WINGS
The wing is critical for the stability of the foil. The wings maximize control
and stability without unnecessary drag. The wing selection is based on
the rider’s weight, riding style, and conditions.
150 Surf V2
An excellent choice
for sportier eFoil
riding. The 150 has
a perfect wingspan
to match this year’s
board lineup.
It offers excellent
speed, carving, and
efficiency.
A shop favorite!
200 Surf V2
For eFoiling, the 200
Surf V2 is what we
call our “bread and
butter.” Foiling is not
about going fast or
slow. It’s about the
balance under your
feet and the glide.
This wing is the true
magic carpet that
does it all and feels
amazing. Try a few
different tail wings to
mix it up a bit.
250 Surf V2
The big brother to the
200 Surf V2.
If you’re a larger rider
and need some extra
float and stability,
this is a great option.
For eFoiling, this
wing can offer a lot
more stability and
lower riding. You can
also pair it with a
shorter board to gain
maneuverability at
lower riding speeds.
