What are the slalom officials in Canoeing?

Section 4: Players & Officials

Boat classes: K1 (1 paddler), K2 (2), K4 (4), C1 (1), C2 (2). Olympic events cover a subset of these per programme cycle.
Competition format: Heats → Quarterfinals (if needed) → Semifinals → Finals (A final for medals, B final for places 9–17). The fastest qualifiers from each round advance.
Seeding: Athletes are seeded into heats based on world rankings to avoid top athletes meeting too early
Lane allocation: Fastest qualifiers placed in center lanes (4, 5) for the final, as center lanes are least affected by reflected waves from shore

Boat classes: K1 (men/women), C1 (men/women), K1X Kayak Cross (men/women)
Format (K1/C1): Qualification (2 runs, best counts) → Semifinal (1 run) → Final (1 run). Each run is a timed individual descent through all gates.
Start interval: Athletes start individually at intervals of approximately 90–120 seconds in slalom. Two athletes are never on the course simultaneously in traditional slalom.
Format (Kayak Cross): Time trial for seeding → Head-to-head rounds (4 athletes per heat). Top 2 advance each round through to the final.

Starter: Gives the start commands ("Ready... Set..." + electronic tone or gun). Monitors for false starts via the alignment system.
Aligner: Ensures all boats are properly positioned in the alignment system before the start signal
Umpires: Travel alongside the race in motorboats, observing for lane violations, interference, and other infractions
Finish judges: Operate the photo finish system and verify transponder timing results
Boat control officials: Inspect boats before and after races to verify compliance with length and weight regulations

Gate judges: Positioned at each gate (or group of gates) to observe whether the paddler correctly negotiates the gate and whether any touches occur. Each gate has 2 judges who must agree; disagreements are reviewed by the section chief.
Section chiefs: Supervise groups of gate judges and resolve disputes about touches or missed gates
Chief Judge: Overall authority on the course. Reviews video evidence for disputed gate judgments.
Timekeepers: Electronic timing from start to finish, recorded to 1/100th of a second
Video review: All gates are covered by cameras. Official video review is used for protests and may overturn gate judge decisions.
