Racing shells are ultra-lightweight craft built from carbon fiber, Kevlar, or honeycomb composite materials. The hull is typically only 1–3 mm thick.

Key Fact: Racing shells must be fitted with a soft rubber bow ball of minimum 40 mm diameter for safety.

Sculling oars: 285–295 cm (9 ft 4 in – 9 ft 8 in) in length, with smaller blades. Each rower uses two.; Sweep oars: 370–385 cm (12 ft 2 in – 12 ft 8 in) in length, with larger blades. Each rower uses one.; Blade shapes: Cleaver (hatchet) blades are standard in modern racing; traditional Macon bla...

Riggers: Metal or carbon fiber frames extending from the hull that hold the oarlocks. Rigger height and spread are adjustable.; Sliding seat: Each rower sits on a wheeled seat that rolls along tracks (slides), allowing use of the legs during the drive phase.; Foot stretcher: Adjustable plate wher...

Coxswains use a cox box — an electronic amplification system with speakers mounted in the bow or stern section. The device also displays stroke rate, elapsed time, and split times.

Distance: 2,000 m (6,562 ft) for all Olympic and World Championship events. Junior and Masters events may race 1,000 m or 1,500 m.; Lanes: Minimum 6 lanes for international competition (8 preferred). Each lane is 13.50 m (44 ft 3 in) wide.; Water conditions: The course must be on calm, sheltered ...

Racing on a straight, sheltered body of water.

The Albano buoy system marks lane boundaries using plastic buoys strung on cables every 10 m (33 ft). Buoy colors change at the 250 m and 1,750 m marks (typically red for the first and last 250 m, white or yellow for the middle 1,500 m) to help crews judge their position and pacing.

Start: Boats are aligned using an Albano alignment system (fixed platforms with mechanical boat holders) or individual stakeboats held by volunteers. The starter is positioned behind all boats and verifies alignment before the start command.; Finish: A photo-finish camera captures the exact momen...

Crew sizes: 1 (single), 2 (pair/double), 4 (four/quad), 8 (eight). Eight includes coxswain (cox) who steers and calls commands.
