Whether you’re preparing for a competitive race, embarking on a challenging cruise, or refining your sailing skills, this app empowers you with the tools and insights needed to excel on the water.

If you do not want to use your own jx40_user_setups.kl file you can still try the app with an example file made available in a .zip file below. The downloadable file is the original jx40_user_setups.kl file that comes with Hydrofoil Generation Version 1.0.1,...

Navigating the intricacies of JX40 yacht setups requires a nuanced understanding of sail and foil control. Each adjustment influences how the boat handles and performs across different sailing conditions.

Understanding Setup Adjustments:

• Sail Twist: This adjustment modifies the curvature of the sail. Increasing twist reduces the power generated, making the sail more forgiving in gusty conditions but sacrificing some forward drive. Conversely, decreasing twist increases power but requires more precise trimming to maintain control. Sail twist also plays a critical role in the boat's ability to depower quickly, crucial for maintaining stability in strong winds or sudden gusts.
• Sail Camber: Refers to the depth or fullness of the sail. More camber enhances power by maximizing the sail's ability to catch wind, suitable for lighter winds or when maximizing acceleration. Decreasing camber reduces drag, making the boat faster in higher wind speeds but with less immediate power. Camber adjustments are vital for balancing speed and control, influencing acceleration and responsiveness to sail trim changes.
• Rudder Pitch: Adjusting rudder pitch alters the boat's trim by moving the center of lift forward or aft. More rudder pitch moves the center of lift forward, aiding in pointing ability and reducing weather helm. This setting is crucial for balancing the boat's responsiveness to wind shifts and sail trimming adjustments. Rudder pitch adjustments impact both upwind performance by increasing pointing ability and downwind stability by aiding in sail balance.
• Dagger Cant: Controls the angle of the daggerboard relative to the hull. Increasing cant increases lateral resistance, reducing leeway and enhancing upwind performance. It also stabilizes the boat but requires careful adjustment to prevent excessive drag. Decreasing cant improves downwind speed by reducing resistance but can increase leeway. Dagger cant adjustments are critical for optimizing performance across different points of sail, balancing between upwind efficiency and downwind speed.

Example Setup Configurations:

The setup configuration setting for rudder pitch in the game is formatted with a decimal point.

The decimal point is not present on the user_setups.kl file.

For example, if your rudder pitch is set to 1.9 in the game this is equal to 190 on the file. 1.7 in the game = 170, 1.5 in the game = 150 and so on.

Beginner Level Setup:

For stable performance and ease of handling:

• Upwind:
  
  • Rudder Pitch: 190
  • Sail Camber: 6
  • Sail Twist: 20
  • Dagger Cant: 12

• Tacks:
  
  • Rudder Pitch: 150
  • Sail Camber: 9
  • Sail Twist: 21
  • Dagger Cant: 12

• Top Rounding / Gybes:
  
  • Rudder Pitch: 150
  • Sail Camber: 13
  • Sail Twist: 12
  • Dagger Cant: 16

• Downwind:
  
  • Rudder Pitch: 180
  • Sail Camber: 9
  • Sail Twist: 21
  • Dagger Cant: 22

In lighter winds, adjust Sail Twist to 17 upwind and 20 downwind. For medium to high winds (20-22 kts), use 23-24 twist. Use J1 up to 12 kts, J2 for 22 kts, and J3 above 22 kts. Set Ride Height around 90%.

Intermediate - Pro Level Setup:

For competitive sailing and optimal performance:

• Upwind:
  
  • Rudder Pitch: 350
  • Sail Camber: 3
  • Sail Twist: 30
  • Dagger Cant: 30

• Tacks:
  
  • Rudder Pitch: 200
  • Sail Camber: 9
  • Sail Twist: 28
  • Dagger Cant: 12

• Top Rounding / Gybes:
  
  • Rudder Pitch: 200
  • Sail Camber: 13
  • Sail Twist: 18
  • Dagger Cant: 12

• Downwind:
  
  • Rudder Pitch: 350
  • Sail Camber: 18
  • Sail Twist: 28
  • Dagger Cant: 25

In lighter winds, use Sail Twist of 20, Sail Camber of 5-6, and Dagger Cant of 29 upwind, with 22 twist downwind. For stronger winds (20-22 kts), adjust Sail Twist to 33 with 3.8 pitch. Adjust Ride Height around 90-150% upwind, 130-140% downwind. During tacks, set Ride Height to 60%, and for gybes, vary from 90% at the start to 160% during and lowering to 120% at the end.

General Tips and Considerations:

• Experimentation: Every sailor's style and preference differ. Experiment with different setups to find what best suits your sailing style and conditions. Detailed logging of each setup's performance can aid in refining adjustments over time.
• Balance and Control: Aim for a balanced sail trim between the main and jib sails, adjusting both rudder movement and sail controls to maintain stability and speed. Effective control over sail trim and rudder movement ensures optimal performance across all points of sail.
• Wind Conditions: Adjust setups dynamically based on wind strength and direction. Lower setups are ideal for higher wind speeds, while higher setups maximize power in lighter winds. Understanding wind conditions and their impact on sail performance is key to achieving consistent results.

Understanding these adjustments allows you to fine-tune your JX40 yacht setup for optimal speed, maneuverability, and stability across various sailing conditions. Mastery comes from continual adjustment and understanding of how each setting impacts the boat's performance.

Hydrofoil Generation has 4 preset banks,... blue / 0, green / 1, yellow / 2 and red / 3,... all containing 4 individual setups,... 1 - 4.

The blue / 0 bank is the system default and cannot be edited, but the remaining 3 banks can be user defined.

You can adjust the rudder pitch, sail camber, sail twist and dagger cant as well as select a small, medium or large jib.

After configuring your setups you can then activate any setup you want on the fly in the game to adjust for upwind or downwind legs and differing wind as well as wave conditions.

You can also use auto assist 'auto setup' and let your system automatically and dynamically change your setup on the fly while racing.

Here is a look at the four setup banks, blue is system default and green, yellow and red are all user defined.

After entering a server or a practice session and configuring the setup banks you will see your setup information in the center at the bottom of your game screen.

The bank you are currently using is indicated by the color, (blue, green, yellow, red) and the actual active setup is the colored number, 1 - 3.

 Hydrofoil Telemetry Chart Plotter

Upload a race course or location .kl file to view the layout of the entire race course or location. The coordinates for each individual object on the race course or location file will be displayed on a cartesian grid. The grid allows for full mouse control,... zoom, pan, auto scale, reset, etc, for optimum viewing.

You can edit the coordinate values for each object in a .kl file that are displayed inside the text editor viewport and the displayed coordinates on the grid will dynamically move to their new location. This gives you a real time accurate visual representation of the entire course / location both before and after editing without having to make the edits inside the game in developer mode.

Then simply download your new .kl file or copy and paste the data into your own file and install it in the appropriate folder of your HG content and server content folders,...
