eMast AL Cruise without Motor

Freeride

The eMast AL Cruise without motor is a durable alloy mast with the motor pod positioned 15 cm above the fuselage. It includes the Electronic Speed Controller (ESC), the top plate with a connector, and internally routed cables. Please note that the following components are required to use the product: motor, bell, propeller, cable, leash (not necessarily needed if you mount the battery box on the board), and fuselage adapter. This eMast is suitable for both expanding your existing setup and serving as a replacement mast if your current mast is damaged while the other parts are still intact.

FULL DESCRIPTION

The Foil Assist Cruise Alloy Mast is designed for beginners and intermediate foilers, making it an excellent choice for those looking to get into the sport of foiling, as well as for schools. With a length of 80 cm, this mast is slightly shorter than the Foil Assist Mast AL, enhancing its suitability for novices while still performing well in swell, choppy waters and waves.

With the Foil Assist Cruise Mast AL, the motor pod is positioned lower on the mast, precisely 15 cm above the fuselage. Despite this adjustment, it retains all the features of the Foil Assist Mast AL, including internally routed cables that ensure better glide and maneuverability, and a rigid, surf-inspired profile for precise control and instant responsiveness, minimizing drag for smoother and more efficient sessions.

Safety is paramount with the Foil Assist Cruise Mast AL; therefore, it comes with an optional propeller safety guard that attaches easily with three small screws to the motor. This feature is especially recommended for those new to foiling with electric propulsion. However, please keep in mind that using the safety guard increases energy consumption, resulting in more drag and reduced battery runtime. To counter this, we recommend pairing the mast with larger foil and board sizes.

Equipped with a powerful folding gear propeller, the propeller only opens and rotates when activated and automatically closes upon releasing the ring controller button, ensuring minimal drag and enhanced safety. If additional torque is needed, the plastic propeller blades can be replaced with more robust and also sharper aluminum power propeller blades.

The placement of the receiver in the battery box on the harness ensures optimal signal transmission to and from the remote, providing reliable power throughout your session.  
The batteries offer an average runtime of approximately  30 minutes, although actual ride time can vary based on skill level, weight, riding conditions, chosen speed, board and  foil size.

Designed for complete modularity, the Foil Assist Cruise Mast AL allows for effortless swapping of motor and connector cables within the entire Assist mast range. Its fuselage adapter system is compatible with most major foil brands, including Duotone, F-One, Armstrong, Gong, Axis, Lift, North, Code, Sab, AFS, and KT. This compatibility grants you the freedom to utilize your preferred foils while reaping the benefits of the advanced Duotone Foil Assist technology. Additionally, the mast can be attached to any mid-length foil-board featuring standard US foil tracks, enhancing its versatility.

To maximise battery runtime with your Foil Assist, we recommend using a front wing with a surface area of 900 cm2 or larger, along with a board that has a minimum volume of 35 L. For beginners and schools, we particularly recommend combining the Foil Assist with the Midfish Air board. This setup also allows the battery box to be positioned on the tail of the board, offering an alternative to using the harness.

While the assist system may not offer the range or full integration of traditional eFoils, it is significantly smaller and lighter, enabling configurations that dedicated eFoils cannot achieve. Most importantly, you can run this assist setup using your existing boards and foils. To increase the ride time, we recommend purchasing an additional set of batteries.

Wing Foiling Gear

I cannot sing enough praises for H2O Sports! I have over the years made small purchases because they’ve been the most competitive online but recently I bought some new wing foiling kit and there was some slight damage to the alloy mast - well H2O’s aftercare was second to none!! They were instantly chasing down a replacement part and happy for me to be using the old part (albeit a bit bent) whilst waiting for the replacement. So refreshing to experience such great customer service.
Many many Thanks! - will be ordering more and more from this company!!!

Duotone Unit SLS 2025

After purchasing this wing earlier this year it has noticeably made tacks so much smoother and overall upgraded my riding. I bought the 3.0 and 5.0 metre and my 3.0m flies very well in both underpowered and overpowered conditions

Duotone Carve DLAB and Unit SLS wing

I purchased the Unit SLS 2025 wing earlier this year and it has made tacks so much smoother and upgraded my riding. I also bought the Duotone Carve 3.0 D/LAB 2025 with the 800 front wing and once again it’s been a game changer, having a great amount of glide which works perfectly for both wingfoiling and kitefoiling!
All thanks to the H2O team that always have loads of knowledge, passion for watersports and go above and beyond!

Preferring not to throw away my (now discontinued) North Red boom which had a broken cuff, I called H2O to see if there was any way to salvage it. I spoke with Matt who was very knowledgeable and helpful but came off the phone somewhat resigned that I might not be able to get the part. However to my surprise a little while later I was blown away (with a force 5) when I got a call to tell me he’d sourced one for me. And here I am now, a week on, with all the bits I need to get back on the water; whoever said people don’t have time to help others! So the moral of this story is have a little faith and try H2O!

Light wind lift

Ordered a 1350 Glide 2.0 to progress on to from my 1750 aero free. Being a heavier rider I've found it's now my go to foil wing, initially a bit harder to get on the foil compared to the aero free but once up it feels completely effort less! Thanks to the team for getting me sorted out 🤙

Duotone slim 2.0 Dlab 2.0 carbon mast

My new mast arrived from H20. Sports and it was so worth the wait. You immediately notice how much stiffer it is compared to the v1 carbon version when riding. The foil feels more responsive and direct .It also glides longer in transition s and riding bumps.
Its well worth the upgrade in my opinion.

Duotone Float 5 m is a summer light wind weapon

I bpught this wing to replacr my Unit 5.5 m wing for tje summer breezes as i never liked using big wings. This wing is really powerful in the low end and allows you to pump really efficiently to get on foil with a bit of technique.
You can size down by half a metre with this wing compared to a Unit.
Its still fast and so good iwhen you roll into a tack.
Perfect quiver would be a 3 m , 4m & a 5 m in the Float for all conditions.
Its a great price too as lower than Dlab and SLS wings but with great performance.

Duotone sky surf/sky style, Duotone unit, Dlab foil range.

As one of the H2O riders I have really enjoyed the variety of kit H2O have available. Including the Duotone sky surf 35Ltr which quickly become my favourite board because of its shorter and thicker shape while being low in litres it still allows me to get it out the water in some lighter winds. However it comes into its own when the wind is strong and the waves are pumping with its incredible manoeuvrability. Paired with the Duotone units (that are light weight and precisely balanced) wave riding is a dream.

New to downwind boards and loving it!

I've been one of those riders who thought one board was enough. Turns out a downwind board has opened up so many more days on the water. I cant believe how easy this beast gets going in 6 knots. I use my 8' board with the 1100 and 1595 Duotone Glide. It's like a whole new sport. Whilst I've tried paddling up, I think I'll stick to winging for now (although can't wait to try the Stash Parawing).

Enhanced low-end power, stability, and maneuverability at a great price

Lots of the benefits of the DLAB Unit but without the price tag. Strong, light, and powerful. It's been great in all conditions, handles really well when over powered. I bought the 3.5, 4.5 and 5.5 to cover all eventualities. Personally I prefer the handle option which works really well with my harness. Matt and the team really helpful in deciding on the sizing.
