A random draw takes place the day before the season begins to establish the initial ladder order.

Riders may enter up to one month after the season start. Late entrants are randomly seeded among that week's new riders and placed in the lower half of the ladder.

Start: March 15
End: June 15

Riders are arranged in a vertical ladder. Movement occurs only through official challenges, logged races, and designated events.

• Riders may challenge up to 5 spots above.
• Unlimited challenges, but only one active challenge at a time.
• A challenge must be completed and logged before issuing or accepting another.
• Challenged riders must accept unless already in an active race.

All ladder matches are Best-of-1. Course, how to start, where to finish must be mutually agreed upon before the race starts.

Special circumstance rules for the parawing.

95% Rule

Propulsion Zones and 95% Foil Rule

The course is divided into three propulsion phases:

1. Start Zone — Up to 10 and not more than 30 seconds.
2. Foil-Only Race Zone
3. Finish Zone

• The parawing may be used for propulsion only in the Start Zone and Finish Zone.
• After sustained foiling is achieved, riders must remain on foil for at least 95% of the remaining race duration.
• Brief touchdowns for safety or correction are allowed.
• Extended displacement riding or repeated wing-assisted recovery is prohibited.

On Foil

Defined as: Board fully supported by hydrofoil lift and not operating in displacement mode.

Stash Mode

• After sustained foiling, the parawing must be fully depowered and stowed within a reasonable time (e.g. 10 seconds).
• After stowage, the parawing may not be redeployed except for safety.

Redeploy

• If fully stopped and off foil, redeploy is allowed only to re-initiate sustained foiling.

Shame Rule

• GPS review may be used to evaluate compliance with the 95% foil requirement and propulsion restrictions.

The Honor System — Rider Declaration Rule

• By entering, competitors affirm compliance with both the letter and spirit of the propulsion rules.
• The event operates under an honor system and adherence is a condition of participation.

If the challenger wins, they move into the higher position and the opponent drops one spot. Results must be logged within 24 hours.

Riders must complete one race every 7 days or accept a valid incoming challenge to remain active.

Open to all riders. Finals use a 1-spot-up challenge format, single race. Finals determine final season rankings and the Season Champion.
