What is slalom course in Canoeing?

Section 3: Playing Area

A purpose-built regatta course on calm, flat water. Specifications:

Distances: 200 m (sprint), 500 m, and 1000 m. The 200 m course uses the final 200 m of the 1000 m course, with a separate start area.
Lanes: 9 racing lanes, each 9 m (29.5 ft) wide. Lane markers (buoys) spaced at 10 m intervals along the course. Lanes are numbered 1–9 from the nearest shore outward.
Water depth: Minimum 3 m (9.8 ft) across the entire course to prevent wave reflection from the bottom affecting boat speed
Start system: Mechanical alignment system holds the sterns of all boats until the start signal. Boats are aligned flush at the stern, not the bow, to prevent advantage from boat length differences.
Finish: Photo finish system with cameras aligned perpendicular to the finish line. Transponder timing records to 1/1000th of a second. The bow of the boat must cross the finish line.
Wind protection: Venues are ideally sheltered from cross-winds that create unequal conditions across lanes. Wave-damping systems may be used.

Length: 200–400 m (656–1,312 ft) of whitewater channel
Water: Artificial (pump-recirculated) or natural river. Artificial channels allow consistent, repeatable water conditions for fair competition. Water flow rate typically 10–15 m³/s.
Gates: 18–25 gates suspended from overhead wires by adjustable cords. Each gate consists of two poles hanging 15–25 cm (6–10 in) above the water surface, set 1.2 m (3.9 ft) minimum apart.
Gate colors: Green/white striped poles indicate downstream gates (paddled in the direction of water flow). Red/white striped poles indicate upstream gates (paddled against the flow). Minimum 6 upstream gates on the course.
Gate numbering: Gates are numbered sequentially and must be negotiated in order. Gate numbers are displayed on boards above each gate.
Course features: Eddies (calm water behind obstacles), waves, holes (recirculating hydraulics), drops, and current differentials. Course designers use movable obstacles or adjustable water flow to create challenging features.

Length: Approximately 250–350 m modified slalom course
Start ramp: Elevated platform where 4 athletes launch simultaneously on the start signal, sliding down a ramp into the water
Eskimo roll gate: A mandatory section where athletes must capsize and perform an Eskimo roll (self-righting maneuver) before continuing. A cross-beam is positioned above the water to force submersion.
Gates: Fewer gates than traditional slalom (typically 6–12), positioned to create a racing line with multiple possible routes
Contact zone: Designated sections where incidental boat-to-boat contact is expected and permitted. Deliberate obstruction remains prohibited.
