Purely designed as a windsurf foil board, the Alien enables all the variables to work in harmony
and move beyond simply balancing on a foil to WINDSURFING on a foil. A functional foil board
with refined details that makes foiling both accessible AND desriable.
The Alien development program was initiated when the disappointment of bolting a hydrofoil to
a normal windsurf board was realized. By analyzing and gaining a deep understanding of the
new variables that foiling introduced, we saw that specific foi-loriented equipment was required
to elevate the experience to a true windsurfing sensation; blasting in control and carving turns
rather than balanced on top, nervously trimming.
The differences between the Alien and a normal freeride are many; shape, length, rocker, stance,
pretty much everything. But this new geometry works in conjunction with the foil and rig to
deliver balance, and a new windsurfing world to any competent wnidsurfer. It opens up more
locations to windsurf, and can double or triple your days on the water.
Stable enough for your first flights, the Alien has the considered details to deliver performance so
The volume distribution is very important on a foil board as it can be used in much
lighter winds than you need to waterstart. So uphauling is an important consideration,
and the Alien has enough volume forward to allow traditional uphaul technique with one
foot either side of the mast base. A lot of volume in the back half of the board allows
you to get into the straps before the board is even moving, and then kick-start up onto
Shorter length reduces the leverage and lift required by the foil to get the board out of
the water and keep it there. So the Alien is much shorter than normal freeride boards,
but still has enough length to be able to use the nose area for down-force at high
speeds, balancing the lift from the foil. Having some length at the front also softens
re-entry, minimizing catastrophic touch-downs.
The width of the board matches the widths of the foils it’s designed for. Too wide and
the board has too much leverage over the foil and it’s easy to overpower the foil or not
have enough support. Too narrow and the foil can dictate where the board goes. So
we balance it up – Alien widths are 65-85cm wide, and designed for similar width foils.
The board is but a single part of the foiling windsurfer, and must work in harmony with other components; the foil and the rig.
The geometry of all 3 components (Foil, Board, Sail) work together to promote an upright stance. This requires only small
movements for the rider to trim the ride – less effort and a quicker response to control increasing or decreasing lift.
With everything working together, the balance of flight is effortless.
To achieve balance, the mast track is positioned further back to keep the rig standing vertical rather than the traditional raked
back position. A vertical rig is more stable, and positions the sails’ CoE directly above the lift of the front wing.
The rider’s feet are positioned either side of the front wing, and straps are positioned closer together for a more upright
stance. This allows smaller movements to maintain foil trim, and keeps the riders weight directly above the foil lift.
The foiling stance is more rotated outwards towards the rail. Less load on the rig means the twist angles necessitate more
