DETAILED DESCRIPTION
A set designed to get you on the water right away
Instead of piecing together your setup one by one, this complete set brings together the motorized mast, board, Front Wing, and stabilizer in a single, perfectly matched configuration. You choose the board volume, Front Wing surface area, and stab that best suit your body size and riding style; the rest of the electrical system is already there, including the harness, batteries, charger, and remote.
Powerful Assistance for Easier Take-offs
The eMast D/LAB mast delivers an impressive 33 kg of thrust via an integrated motor. This makes your take-offs significantly more accessible. You'll especially feel the assistance during the kick-out. This allows you to use smaller wings and effortlessly link sections in prone or downwind.
The Midfish: A Board Designed for Assist Foiling
With its mid-length shape and carbon construction, the 2026 Midfish promotes early take-offs and maintains a reactive glide once you're flying. Four volumes are available, from 38 to 78 L: smaller volumes are ideal for lighter or more experienced riders. Larger options provide increased initial stability and versatility.
Choose your Crest D/LAB Front Wing and stabilizer
The Crest D/LAB is available from 550 to 1050 cm². Larger surfaces offer earlier take-off and more forgiveness. Smaller sizes prioritize speed and aggressive riding. For the stabilizer, the PX D/LAB delivers glide and straight-line stability. The Tail S provides more responsive steering in turns.
Simple, secure control
The index-finger remote lets you adjust power without ever letting go of the board. A double-click prevents unintentional starts. Simply releasing the remote immediately cuts the motor. This gives you peace of mind when you take a tumble.
Range and care
The charger recharges both batteries in under an hour and includes a discharge function. This preserves their lifespan. Range typically falls between 30 and 60 minutes, depending on your usage, setup, and conditions. For routine care, a quick freshwater rinse after each session is all it takes.

FAQ
What exactly is included in this complete set?
This complete set includes the eMast D/LAB mast with integrated motor, the Midfish 2026 board in your chosen volume, the Crest D/LAB Front Wing in your preferred surface area, your selected D/LAB stabilizer from three options, the eHarness with its battery case, two 7A batteries, the charger and its connectors, and the eRemote Watch Ring remote. Please note that the fuselage and the board connection plate are not included.
Which fuselage should I choose?
The fuselage is not included with this set; it's the crucial component that connects the Front Wing and the stabilizer to the mast. The D/LAB mast utilizes the molded 3BS connection, so a Duotone Aero AL 3BS fuselage (available in 60, 66, 74, and 90 cm) will fit directly. If you're using an Armstrong foil, you'll need the Armstrong E-fuselage, which is available as an accessory. The D/LAB mast is only compatible with Duotone and Armstrong foils. If you have any doubts about compatibility with your current gear, please call us before ordering.
How is the price calculated?
The foil assist components of the set (mast, harness, batteries, charger, remote) form the base price. The chosen board volume, Front Wing surface area, and stabilizer are then added to this, with the displayed price updating automatically with each configuration change.
Who is this set for?
This set is ideal for intermediate to advanced riders who want a cohesive package without having to piece it together, and who are looking for take-off assistance for prone, surf foil, SUP foil, or downwind riding.
Which board volume should you choose?
The Midfish is available in 38, 48, 58, and 78 L. For a comfortable take-off, choose a volume close to your body weight in liters. Opting for a smaller volume will make the board livelier, but it demands more skill. Thanks to the electric assist, you can comfortably ride a smaller volume than you would with a classic foil.
Which Front Wing surface and stabilizer should you choose?
The Crest D/LAB ranges from 550 to 1050 cm². Larger surfaces offer earlier take-off and more forgiveness, while smaller sizes prioritize speed. For the stab, the PX D/LAB (37 or 40 cm) delivers glide and straight-line stability. The Tail S provides more responsive steering in turns.
What range can you expect?
You can expect a range of 30 to 60 minutes, depending on your use, setup, and conditions. The charger can fully recharge both batteries in under an hour and includes a discharge function to help preserve their lifespan.
How do you care for the set?
To ensure longevity, rinse the entire set with fresh water after every session. Make sure to completely dry the remote and battery case before storing them. Recharge the batteries regularly, and for extended periods without riding, utilize the discharge function. Always check the propeller, connections, and the tightness of all screws before each outing.
