iFLY15 Ultimate One Design vs iFLY RAZZOR Pro
Foiling Sailboat Recommendation: Which iFLY Is Right for You?
Defined One Design Performance or Maximum Active Foil Control?
This foiling sailboat recommendation is based on extensive development, testing and real-world sailing experience with both iFLY configurations.
The iFLY15 Ultimate One Design and the iFLY RAZZOR Pro share the same lightweight foiling catamaran platform, four T-Foils, and the advanced iFLY FlySafe® Active Foil Control system. Both are designed for sustained foiling upwind and downwind.
FlySafe® automatically controls the main foil flaps independently on each hull to stabilize flight.
The real question is not whether you want high-performance foiling. It is how you want to access, control and develop that performance.
The Recommendation at a Glance
iFLY15 Ultimate One Design: Stable High-Performance Foiling Upwind and Downwind
The iFLY15 – Ultimate One Design is designed for intermediate dinghy and catamaran sailors with trapeze experience who want a defined and balanced setup with automatic flight stabilization.
It allows the sailor to focus on apparent wind, steering, sail trim, boat balance, tactics and carrying speed through manoeuvres. It is the more direct route into serious high-performance foiling, while still offering substantial long-term development potential.
- Defined and balanced One Design configuration
- Takeoff from approximately 8 kn of wind
- Stable foiling upwind and downwind
- Single-handed or double-handed sailing
- Training, coaching and One Design racing
- Focus on sailing technique rather than continuous rake adjustment
iFLY RAZZOR Pro: Maximum Sail Power and Active Rake Control
The iFLY RAZZOR Pro is designed for experienced performance sailors who want to actively shape the balance and full performance of the platform.
Its larger rig, powerful sail options and active main foil rake control create a fundamentally higher performance level, from takeoff at approximately 7 kn of wind to demanding high-speed foiling.
- Active iFLY Main Foil Differential Technology
- Takeoff from approximately 7 kn of wind
- Much larger and more powerful sail configurations
- Active tuning for different sailing modes and conditions
- Exceptional acceleration and top-end performance
- A more demanding and responsive foiling experience

iFLY15 Ultimate One Design
Defined Setup. Direct Performance.
The iFLY15 Ultimate One Design is configured to make high-performance foiling repeatable and controllable.
FlySafe® stabilizes flight automatically, but it does not remove the challenge of sailing the boat well. The sailor still needs to manage apparent wind, steering, mainsail trim, mast rotation, boat balance, tactics and speed through manoeuvres.
The iFLY15 rewards clean sailing. It is designed for sailors who want to improve their foiling skills, race within a defined configuration and concentrate on making the boat fast around the course.
For sailors who later want to move beyond the One Design setup, iFLY Main Foil Differential Technology is available as an individual upgrade.
iFLY RAZZOR Pro
More Sail Power. Active Rake Control. A Different Performance Level.
The iFLY RAZZOR Pro is built for experienced performance sailors who want to convert substantially more sail power into acceleration and speed.
Its larger rig and sail options extend the performance range from takeoff at approximately 7 kn of wind to demanding high-speed foiling.
The decisive technical difference is the iFLY Main Foil Differential Technology. FlySafe® continues to stabilize flight automatically, while the sailor can actively adjust the rake of the complete main foils differentially.
The adjustable rake can generate more downforce on the windward main foil and substantially increase righting moment. This allows the RAZZOR Pro to carry its much larger and more powerful sail plan with control.
It is more demanding to sail, requiring faster reactions, finer steering and more precise control. In return, experienced sailors can push the RAZZOR Pro much harder and access a far more powerful and responsive level of foiling performance.
Foiling Upwind and Downwind
The defining quality of an advanced foiling catamaran is not one short high-speed run. It is the ability to remain balanced, controlled and efficient across different points of sail.
Both iFLY models are designed for sustained foiling upwind and downwind. The iFLY15 Ultimate One Design provides a defined setup that allows the sailor to concentrate on speed, angles and manoeuvres. The RAZZOR Pro adds active differential rake control for sailors who want to tune power, balance and performance mode while sailing.
A Fully Modular Foiling Catamaran Platform
The iFLY15 Ultimate One Design and the iFLY RAZZOR Pro are different performance configurations of the same lightweight and fully modular foiling catamaran platform.
The final setup can be adapted to sailing experience, crew weight, local wind and wave conditions, single-handed or double-handed use and long-term performance goals.
Individual Configuration Options
- CARBON or sustainable TENRON® hull construction
- Aluminium or CARBON mast
- Different mast lengths
- Different mainsail areas and sail shapes
- Performance Decksweeper, Pin Top and XXL Square Top sails
- Code F light-wind headsail
- FlySafe® Active Foil Control
- iFLY Main Foil Differential Technology
- Single-handed or double-handed configuration
- Individual equipment and colour configurations
This modularity means that the decision is not limited to selecting a model name. Mast, sail plan, foil-control system and equipment can be selected around the sailor, crew and intended conditions. Depending on the original configuration, individual components can also be adapted later as experience and performance goals develop.
Get Your Personal Foiling Sailboat Recommendation
Selecting the model is only the first step. The mast, sail plan, foil-control system and equipment should match the sailor and the intended conditions.
- Previous sailing experience
- Single-handed or double-handed use
- Total crew weight
- Typical wind range

Frequently Asked Questions
What is the best foiling catamaran for an experienced dinghy sailor?
For an experienced dinghy or catamaran sailor entering full foiling, the iFLY15 Ultimate One Design is generally the more direct choice. It combines serious high-performance foiling with automatic flight stabilization and a clearly defined setup.
When should I choose the iFLY RAZZOR Pro?
Choose the RAZZOR Pro if you already have substantial performance sailing experience and want active main foil rake control, a much larger sail plan, takeoff from approximately 7 kn and the maximum performance level of the iFLY platform.
Can both iFLY models foil upwind and downwind?
Yes. Both models are designed for sustained foiling upwind and downwind. The RAZZOR Pro adds active differential rake control for experienced sailors who want more power, more righting moment and greater control over the performance mode of the boat.
Can both models be sailed single-handed and double-handed?
Yes. Both models can be sailed by one or two sailors and support single or double trapeze configurations.
Can the boat be upgraded later?
Yes. The iFLY platform is modular. Depending on the original setup, sails, mast, foil-control systems and other components can be adapted as the sailor’s experience and goals develop.
Is the iFLY a foiling sailboat or a hydrofoil sailboat?
Both terms are technically correct. The iFLY15 Ultimate One Design and the iFLY RAZZOR Pro are high-performance hydrofoil sailboats built as lightweight foiling catamarans with four T-Foils and the FlySafe® Foil Control System.
Which model offers the more direct entry into high-performance foiling?
The iFLY15 Ultimate One Design offers the more direct route because the complete main foil rake does not need to be adjusted continuously while sailing. The RAZZOR Pro provides more active control and tuning authority, but is also more demanding and requires faster reactions, finer steering and more precise control.
