2026 Appletree AppleSlice Prone

AppleSlice Prone

Sizes: 4'0" / 4'2" / 4'4" / 4'6" / 4'8"

ADVANCED PRONE FOIL BOARD

Mix together the well-trusted foil board shapes of Appletree's line up, add a dash of ambition, and you have a prone board for riders looking to amp their progression. If you're chasing performance in the surf, the AppleSlice Prone delivers the lift, control, and carving response you need.

A fuller outline paired with balanced lift distribution makes offers more pronounced front-end lift for easier pop-ups. The beveled rails and tuned bottom edges have more clearance for aggressive turns and more control in transitions. The V-nose and soft water entry reduce chatter and glide you through those most critical sections.

With a wide range of sizes, the AppleSlice Prone covers nearly every surf foiler style — from the versatile surf setups to ultra-small boards for kite and wake use to larger sizes with a forward foil box for better balance with small foils in areas with stronger conditions. If you're looking for a board that can handle the steep waves, support you in transitions, and push you forward in your progression, the AppleSlice Prone is built to keep up.

What Appletree has to say:

The AppleSlice Prone is born from the DNA of Appletree’s most trusted shapes, fused into a single platform for prone foil riders looking to push their progression. Whether you're an ambitious intermediate or a seasoned pro, this board delivers the explosive response, early lift, and refined control needed in steep, high-speed surf.

Designed for Progression

With a fuller outline to support efficient paddling and a carefully tuned lift profile, the AppleSlice Prone allows for smooth, confident takeoffs. The addition of increased nose lift improves control on steeper drops, while aggressive bevels and harder edge lines support smooth rail transitions and quick release. Even when carving at speed or navigating foam.

Versatile Sizes

The AppleSlice Prone is available in Appletree’s signature carbon finish or with custom color options. Sizes range from compact prone setups to ultra-small models suitable for kite and wake use.

Features:

• V Nose: Adds front-end stability during paddling and takeoff, reducing chatter in critical moments.
• Performance Rail Line: Tuned bottom edges for smooth, high-speed carving transitions.
• Beveled Rails: Extra rail clearance during aggressive turns to prevent catches.
• Soft Water Entry: Gentle rail-to-water engagement for uninterrupted flow.
• Balanced Lift Distribution: Pronounced front-end lift for fast, easy pop-ups in steep sections.
• Offset Rear Inserts: Allows fine-tuned foot positioning for optimal leverage and control.
• V Front Inserts: Ergonomic foot placement adaptable to various stances and conditions.
• Forward Foil Box (on larger sizes): Enhances balance and compatibility with smaller foils in bigger surf or strong wind conditions.

Construction

50K CLOSED CELL FOAM

It all starts with the core and every board we make starts with a foam core of our very own 50K closed cell foam. This foam is formalized exclusively for us, it is not used in any other board in the market.

The foam can withstand 50.000 kg per square meter, while staying very light, and most of all very flexible. Another plus of our 50K foam is that it is closed cell, meaning that the foam will not take in water, and the board will not blow out when it gets hot.

100% CARBON FIBER CONSTRUCTION

All our foil boards are produced in our 100% carbon fiber construction. You want carbon fiber in a foil board for its stiffness and strength. A stiff board will give you the best control and response from the foil. Also stiffness will make pumping the foil much more effective. With carbon fiber we are able to make the board extremely strong while really light at the same time.

The most stress in a foil board is in the connection of the foil to the board. So this is where we put extra care and attention to make it the strongest connection available. The foil mount is CNC cut with the board, for the highest precision. We only use FUTURES oneshot boxes as they are the strongest in the industry. The boxes are placed in a panel of ultra high density PET honeycomb. This PET honeycomb itself is sandwiched in carbon again. Meaning there is carbon fiber both inside the board and outside. The honeycombs open structure ensures a solid connection between inside and outside, fusing everything together into a solid block.

Our lamination is completely different as well. We use a vacuum technique developed in house, where we layer all the carbon fiber, and reinforcements on the board dry. Then we extract all the air from the bag and inject the epoxy resin under pressure. This results in the tightest lamination possible, with the best ration between fiber and epoxy. It also gives 100% connection to the core so the boards do not delaminate. Extra patches under the feet prevent heel denting.

Inserts in our foil range are made from blocks of high density material. And can be customized position wise. These blocks are also fused to the core so they never pull out.
