DETAILED DESCRIPTION
A set designed to get you on the water right away
Instead of assembling your setup piece by piece, this set combines the motorized mast, board, front wing, and stabilizer into a single configuration. You choose the board volume, front wing size, and stab to match your build and riding style; the rest of the electrical system is already included: harness, batteries, charger, and remote.
Powerful Assistance for Easier Take-offs
The eMast D/LAB delivers 33 kg of thrust from its integrated motor, making take-offs much more accessible. You'll really feel the assist during the kick-out, which lets you use smaller wings and link sections in prone or downwind without having to pump so hard.
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, while larger options provide increased initial stability and versatility.
Choose your Crest D/LAB front wing and stabilizer
The Crest D/LAB front wing is available from 550 to 1050 cm²: larger sizes provide early lift and more forgiveness, while smaller ones prioritize speed and commitment. For the stabilizer, the PX D/LAB adds glide and straight-line stability, while the Queue S offers sharper, 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, and simply releasing the remote immediately cuts the motor, giving 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 to preserve their lifespan. Ride time is typically 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?
The eMast D/LAB with integrated motor, the Midfish 2026 board in your chosen volume, the Crest D/LAB front wing in your chosen size, your choice of one of three D/LAB stabilizers, the eHarness with its battery box, two 7A batteries, the charger with all cables, and the eRemote Watch Ring. The fuselage and top plate are not included.
Which fuselage should I choose?
The fuselage is not included in this set. It's the part that connects the front wing and stabilizer to the mast. The D/LAB mast uses the molded 3BS connection, so a Duotone Aero AL 3BS fuselage (available in 60, 66, 74, and 90 cm) is a direct fit. If you are using an Armstrong foil, you will need the Armstrong E-fuselage, sold separately as an accessory. The D/LAB mast is only compatible with Duotone and Armstrong foils. If you're unsure about compatibility with your current gear, give us a call before you order.
How is the price calculated?
The foil assist components (mast, harness, batteries, charger, remote) make up the base price. Your chosen board volume, front wing size, and stabilizer are then added. The total price updates automatically as you select your options.
Who is this set for?
For intermediate to advanced riders who want a complete, matched setup without the guesswork. It provides take-off assistance for prone, surf foil, SUP foil, or downwind riding.
Which board volume should you choose?
The Midfish comes in 38, 48, 58, and 78 L. For an easy start, pick a volume in liters close to your body weight. A lower volume makes the board more responsive but requires more skill. The electric assist makes it easier to ride a smaller board than you would with a standard foil.
Which Front Wing surface and stabilizer should you choose?
The Crest D/LAB front wing is available from 550 to 1050 cm². Larger sizes provide earlier lift and more forgiveness, while smaller sizes are faster. For the stabilizer, the PX D/LAB (37 or 40 cm) offers great glide and straight-line stability, while the Queue S delivers more responsive turning.
What range can you expect?
Expect a ride time of 30 to 60 minutes, depending on usage, your setup, and the conditions. The charger recharges both batteries in under an hour and has a discharge function to preserve their long-term health.
How do you care for the set?
Rinse the whole set with fresh water after every session. Make sure the remote and battery box are completely dry before you store them. Charge the batteries regularly, and use the discharge function if you won't be riding for a while. Always check the propeller, connections, and that all screws are tight before heading out.
