E3 Wing / Prone / Downwind


We are excited to be releasing our new line of E3 foil boards. The E3 designs are an evolution of our E2 foil boards but have significant new design features.

The E2 range was designed to maximize stability within the shortest platform possible to accentuate maneuverability and lift off.

The new E3 range is designed to maximize early lift off by increasing the efficiency of the hull. Simply put, this has been achieved by elongating the subsurface footprint and eliminating all horizontal edges that increase drag at sub planning speeds.

The longer and more interesting process to get to this point starts here…After the release of the E2 range Dave went down a rabbit hole of chasing the dream of downwind prone foiling.  No Paddle. No ski. Just the wind, a board, and a foil.

Now we know that this application of foiling is, shall we say, unique and reserved for a small group of board riders who happen to live in areas with suitable conditions (like the north shore of Maui). But stick with us here, just like the landing of man on the moon…the real contribution to society was not the actual landing on the moon but all the technological breakthroughs learnt along the way to get to the moon that have been passed along to us.

And just like the journey to the moon, Dave’s goal of chasing the dream of making downwind prone foil boarding a possibility led him to focus on the efficiency of the board. Many prototypes and humbling sessions on the water have resulted in a new line of boards that have directly benefited from this Journey. Dave learnt what designs and features worked, and more importantly what did not. All this knowledge has been incorporated into the E3 line of foiling boards.


Inherent design features of the E3 Kalama Performance designs.

Full carbon, high density foam molded PVC sandwich construction.

All boxes and foot strap inserts are reinforced with high density foam insets and additional carbon.

We use a resin tint finish layer resulting in a tough and paint chip free construction.

Tip to Tail (T2T) dynamic hull design

  1. The hull is designed to minimize drag from horizontal edges at sub planning speeds.
  2. Foiled subsurface outline to increase initial acceleration.
  3. Progressive vertical bottom edge to promote early lift-off.
  4. Progressive chine towards the tail reduces drag at lift-off.

Chine rails

  1. Promote early lift-off.
  2. Reduce drag on touch downs.
  3. Allow sharper turn angles without touching the water.

Rounded and soft nose edges

  1. Greater level of efficiency at sub planning speeds.
  2. Early lift off through greater acceleration at initiation of take-off.

High Volume Designs

  1. Higher paddling efficiency
  2. Earlier lift off through higher buoyancy
  3. Increase stability to width ratio

E3 Foil Wing / Prone / Down Wind

The Wing / Prone boards are a breakthrough in prone foil surf and foil downwind. They are also very suitable for Wing sailing.


The Wing / Prone boards come in 4 sizes. 5’3”, 5’9”, 6’1”, 6’5”. These boards are longer but narrower than the E2 prone foil boards. The additional length promotes prone wave catching and downwind bump hunting. Kind of like the longboards (or mid length shortboards) of prone foiling.
