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 desirable.
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 foil-oriented 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 windsurfer. 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 as not to be outgrown.
VOLUME
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 the foil.
LENGTH
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.
WIDTH
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 65-75cm wide, and designed for similar width foils.

PREDATOR _FOIL STYLE
MAXIMUM PERFORMANCE. MAXIMUM STYLE. The Predator is a dedicated windsurfing foil board that transcends boundaries. More aggressive than the Alien, it’s engineered to carve, jump and slice through the air with decisive precision. Redesigned for 025, the Predator now delivers enhanced in-flight stability through strategic volume distribution and a lower centre of balance. The purpose-designed nose area is a defining factor in controlled flight and landings. This added stability opens new realms of expression – from foilstyle aerial rotations to foil wave riding. Length is kept short to reduce the lift required to keep it flying and to increase maneuverability. Premium construction keeps the weight significantly below industry standard for real performance. Strategic inboard-only rear footstrap positioning keeps the rider’s weight directly over the foil during jumps and maneuvers, reducing leverage and minimizing breakage risk. As a true windsurf board, a deep-tuttle box is used for reliability, consistency and ease of use. Excess inserts and finboxes have been eliminated, increasing simplicity and reducing weight. Match the Predator with the R4D for the ultimate combo. / 025 UPGRADES / New outline profile / Upgraded materials / Re-shaped nose / Higher stability / Fresh color scheme matching Psycho, R4D, Freek / New size range / Improved weight SIZES: 100 / 115Severne Alien CPT 125ltr + Starboard Windsurf Foil Package
