Duotone Falcon_Fin D/LAB (MTO, no fin) 2027

The FALCON_FIN D/LAB is DUOTONE's D/LAB-tier fin slalom race board for advanced and expert windsurfers competing on fin at PWA, IFCA and club level. Built on race-winning shapes and CUSTOM CNC SANDWICH TECHNOLOGY, it keeps your focus on speed and line, not on the equipment. Beyond Imagination.

FULL CUSTOM D/LAB TECHNOLOGY starts at the core: every EPS block is CNC-milled to its final shape rather than injection-moulded, removing mould-imposed tolerances and saving measurable weight from the start. SINGLE PROCESS TECHNOLOGY then vacuum-bags the top and bottom PVC shields against the core in separate steps — the split that drives the weight-to-stiffness ratio. PVC thickness varies by stress zone instead of running 3mm everywhere. The full layup tops 60 individual parts, nearly 20% more than SLS PREMIUM SANDWICH CONSTRUCTION, and comes in up to 500g lighter than the SLS version and up to a full kilogram lighter than a standard production board.

The material stack reinforces every gram: high-modulus and high-strength carbon fibers, the same high-modulus grade used in aircraft and Formula One; Innegra for tensile strength and ding resistance; exclusive S-glass for roughly 10–20% more stiffness than standard glass; and DUOTONE SENTEX® resin with silicon nano-spheres to cut weight at the resin level.

For this generation the fin box sits slightly further forward, sharpening acceleration and tightening upwind trim without compromising the board's proven balance.

The FALCON_FIN D/LAB comes in eight sizes: 89, 98, 111, 118, 119, 124, 130 and 139 liters. New for this generation, the 130 is derived from the magic 139 — the shape behind the board's light-wind, big-sail dominance — carrying that DNA into a more manageable volume. Sizes from 119 to 139 give you the range to plane early and drive large sails through light-wind heats.

Please note: The FALCON_FIN D/LAB is a Made to Order (MTO) product and is supplied without fin. We recommend checking our RACE D/LAB fin.

FULL CUSTOM D/LAB TECHNOLOGY

The FULL CUSTOM D/LAB TECHNOLOGY is a full custom technology which is one hundred percent identical to high-end custom made boards.

Instead of using a mould to bring the EPS foam core into its final shape each EPS block gets CNC milled. This ensures maximum precision and saves weight. 

Same as with high-end custom board makers the major advantage lays in the processing. We call this SINGLE PROCESS TECHNOLOGY and it is the key to our industry-leading weight-strength ratio. Instead of combining working steps to save time and money every single step follows its individual process. So for example instead of joining the PVC sandwich with the EPS core in a single shot we vacuum-bag the top and bottom PVC shields with the EPS core separately. 

Also instead of using standard 3mm PVC elements for the entire board we use thicker and thinner PVC plates as well according to the stress areas which makes the board lighter yet stronger.

For all D/LAB boards we use our most sophisticated layup which consists of more than 60 individual parts and components (nearly 20% more parts than used for our FULL CUSTOM SLS TECHNOLOGY). 

On top we are using the most high-end composite materials available to-date. 

1. All carbon fibres used are a mix of high strength and high modulus carbon qualities depending on the individual requirements of each board section. Our high modulus carbon used can also be found on high-end products like aircraft’s, Formula One cars or our Platinum SLS masts, booms and extensions. 
2. Innegra is a high modulus Propylene with unbeatable tensile and ding resistance. It offers a similar tensile strength to Kevlar, but is significantly stiffer. In addition, Innegra is the best composite fibre to prevent dents.
3. We use our exclusive high performance S-glass fiber with an extra high silica content which offers much higher tensile strength as well as about 10-20% greater stiffness.
4. And finally we are using our exclusive DUOTONE SENTEX® resin impregnated with silicon nano-spheres which helps us to reduce the weight even further without sacrificing durability. 

Instead of using a similar layup on all boards we use a DISCIPLINE SPECIFIC FLEX CONSTRUCTION for all our D/LAB boards since demands on the different disciplines (wave, freestyle, freeride, racing) and conditions vary quite a lot.

1. Racing boards are e made to offer maximum performance (instant acceleration and V-max). Therefore these boards need be as stiff as possible. To achieve this no compromise stiffness we use a super high carbon content on all FALCON D/LAB layups.
2. On wave boards though a certain „give“ is essential since these boards are very short and might become too stiff thus uncontrollable using a full carbon layup. Therefore the GRIP D/LAB boards come with a higher Innegra and S_GLASS+ content. These high-tech composites have a much higher tensile strength avoiding breakages after high landings. To still achieve an outstanding "spring-back" characteristics which makes the board more reactive and has a tremendous effect on the acceleration we use unidirectional Carbon reinforcements in longitudinal direction. 

Last but not least even every single board size has an individual layup. That’s the final stage of individualisation in construction.

The result speaks for itself since the D/LAB boards are up to 500 grams lighter than our SLS boards and up to a full kilo lighter than other semi custom production boards. And it’s the first time that a production board can compete even with the lightest custom made boards out there. 

Yet all of this is achieved without any sacrifice in durability since we always follow our core motto LIGHT DONE RIGHT.

Deck Shape

Flatter deck shape for comfortable stance and maximum control during jibes. 

Recessed mast track area lowering the rig connection, boosting control and aerodynamics by “closing the gap”.

Outline

RANGE SPECIFIC ASPECT RATIO (length vs. width) 

• The smaller the board the higher the aspect ratio >> maximum control plus reduced wetted surface for v-max
• The bigger the board the lower the aspect ratio >> maximum acceleration already at lower speeds

Rail Shape

> The apex of the rail in front of the front straps has been moved up. This has a tremendous effect on the control, as everything just becomes a lot smoother. Makes it very easy to maintain the perfect trim.

> Harder rails underneath the feet allow maximum push onto the fin to let the board fly.

Duotone Premium Strap 2.0

High quality closed cell neoprene for maximum longevity. Only black Lycra coating guarantees maximum comfort as well as maximum durability. The strap features measurement markings to allow you to quickly set up and replicate your individual size. Board specific attachments:

> All World Cup boards come equipped with double-screw plugs to prevent any twist and ensuring the most direct connection to the board

> All other boards come equipped with single-screw plugs to allow a faster repositioning of the straps plus a more comfortable ride due to a certain "give"

NEW - Completely revised and unique design:

+ 20% less weight

+ Significantly reduced elongation for direct connection and to avoid slipping in too far with risk of injury

+ Improved preforming for quick and easy assembly

Duotone Pro Pads incl. wedge

All sizes feature an additional pad wedge between the rear straps raising the toe area allowing to push harder and making the board fly.

The heat pressed diamond grooving pattern protects the EVA against abrasion and provides an extraordinary grip level.

Bottom Shape

FLYING V-SHAPE: increased V in front of the mast track and towards the tail makes the board ride high and loose plus improves control and allows varying jibing radius to attack at the buoy.

The 2 STEP CUT-OUTS reduce the wetted surface. This allows a wider tail outline and due to the further outboard rear strap position the rider can load more power onto the fin for more control and speed.

Rocker Line

Rocker lines developed over decades deliver top speeds in all conditions and ensure maximum control

AI_Fin_3D

Our software is based on math data-driven input. Apart from being much more accurate and faster, complex 3D design tasks such as the perfect profile transition in the crucial tip area, where the fin sweeps backward, would otherwise have been impossible to realize.

This allows us to cross-check the outcome using artificial intelligence to ensure maximum precision. This is the key secret behind the outstanding efficiency of our fins.

SYNCED CURVES CONCEPT

Outline, rocker and rail shape are the 3 key elements that determine how a board feels and performs. In every rocker- and outline there are spots with more or less curvature. The same applies to the degree of rail curvature which changes considerably. To prevent the 3 curves from working "against" each other, the highest priority is to synchronize these curves. Means that in zones with an increased rocker curve, the outline curve is also increased plus the rails have an increased curvature and vice versa.

To our knowledge this complex 3d task can only be performed by our own AI_BOARD_3D software. Testing this concept on existing boards the improvements to each board were so overwhelming that we incorporated this design feature into all 2026 boards.
