HIGHLIGHTS
Built Stronger. Ride It Longer
The Midlength Mk II introduces a new approach to board construction, focused on long term performance and durability.
The molded process ensures every board is produced with consistent shape, flex, and strength, while significantly increasing stiffness and reducing weight. The result is a board that not only performs at a high level but maintains that performance over time.
Direct Connection
A thinner profile combined with increased stiffness brings riders closer to the foil, creating a more immediate and responsive feel.
Energy transfer becomes faster and more efficient, improving control through turns, smoother transitions, and more stable recoveries. The board feels smaller and more agile without sacrificing volume or stability.
Light Where It Matters
Reduced swing weight transforms how the board moves. It feels lighter in motion, easier to control through direction changes, and more responsive during pumping and manoeuvres.
This lighter, more agile feel allows riders to progress with confidence, while maintaining the stability expected from a midlength platform.
Pure Strength Construction
At the core of the Midlength Mk II is a construction built for real world use.
With multi density PVC rails, reinforced standing areas, dual carbon stringers, and integrated carbon foil tracks, every element is designed to handle repeated stress without fatigue or softening.
It is a board built to last, without compromising performance.
Calm, Connected Ride
On the water, the Midlength Mk II feels composed and predictable. The increased stiffness delivers a clean, connected sensation underfoot, allowing riders to stay fully in tune with the foil.
Touchdowns release cleanly, takeoffs feel efficient, and control at speed is improved. The result is a smoother, more intuitive riding experience across a wide range of conditions.

COMMON QUESTIONS

Where's My Order's Tracking Link?
Tracking info is shared via email within 72 hours of most orders being placed. Be sure to check spam or "Promotions" folder in your Inbox, as sometimes our messages land there.
No Tracking Info Displays on Shipper's Website ...
It can take 48 hours for tracking info to display. Rest assured, your package is en route. Make sure to enter the BOL # (Bill of Lading) with no spaces in the tracking field.

Alaska, Hawaii, Puerto Rico?
Yes, we have shipped to these locations for decades by quote. Please share your address, the item(s) you needed shipped, and if an airport cargo depot pickup is possible.
Canada and International Locations?
We ship to Canada lots, and the Caribbean some. Get a quote. We rarely ship items to Europe, Asia, and Australia as it's spendy. Quotes for international orders do not include import duties.

How Can I Be Sure My Board Arrives Intact?
Opt for our $99 "To Nearby Airport" shipping option at checkout. It relies on passenger planes, and offers our safest delivery. More far below.
What if My Board Arrives Damaged?
We'll work with our shipping partner to get you a repair credit or a replacement board. Please send photos of the damaged board (and box) to shipping@bigwinds.com.

My board made it ...
But no foot straps, fins, or vent plug?
Look closely through the packaging. Fins, foot straps and vent plugs are often concealed in a sheath of cardboard that's easy to discard. Also, check inside the board box, and shake the box to be sure. You'll likely dislodge a small box containing the missing items.
