Crew 101: Crew Basics and Terminology

Rowing uses specific vocabulary and a few core concepts that make the sport easier to follow. This page explains boat types, how fall and spring races work, what a coxswain does, and what an ergometer is. A glossary at the end covers common terms you will hear at practice or on race day.

Sweep vs Sculling

Rowers compete in two disciplines. In sweep rowing each athlete holds one oar with both hands. Sweep boats come in pairs, fours, and eights. An eight always carries a coxswain. Fours and pairs may be coxed or coxless. In sculling each athlete holds two oars, one in each hand. Common boats are single, double, and quad. In coxless boats a rower may steer with a foot-controlled rudder or by applying pressure differences.

Boat Classes and Seat Roles

Boat names combine the number of athletes with symbols that show coxed vs sculling. Examples: 8+ is a sweep eight with a coxswain, 4+ is a coxed four, 4− is a coxless four, 4x is a quad scull, 2− is a coxless pair, 2x is a double scull, and 1x is a single scull. Seats are numbered from bow to stern. The stroke seat sets rhythm and rate. The bow seat often helps with steering and is key for balance and technical precision.

How Races Work: Fall Head Races and Spring Sprints

Rowing has two main racing formats. Head races are typically in the fall. They are time trials over longer courses with boats starting one after another at intervals and racing the clock. Courses often include turns and bridges. The fastest elapsed time in a category wins.

Sprint races are typically in spring. Boats line up side by side in lanes and start together, then race a shorter straight course. Scholastic and club regattas commonly run sprints between 1,500 and 2,000 meters depending on the event and level.

The Coxswain

The coxswain steers, manages safety, and runs the race plan. In practice and competition the coxswain serves as an on-water coach who sets calls for rhythm, timing, and tactics, and communicates with officials.

The Ergometer and Performance Metrics

An indoor rowing machine, usually a Concept2, is called an erg. Athletes train on ergs during winter and for testing. The monitor shows key metrics such as stroke rate in strokes per minute, split time per 500 meters, distance, and power in watts. Stroke rate is the number of strokes taken per minute.

Equipment at a Glance

A racing shell is a long, narrow boat designed for speed and balance. Key parts include the oar or blade, rigger, oarlock, seat on wheels, slide tracks, foot stretcher with shoes, gunwale, fin or skeg, rudder, and a bow ball on the bow for safety.

Glossary for Parents

This list is intentionally comprehensive so you can trim it later. It combines on-water, boathouse, and race-day language you will hear from athletes, coaches, and officials.

30 rate 20
A workout of 30 strokes at a stroke rate of 20 per minute, repeated in sets. Rate means strokes per minute, so 20 is the target rhythm.
AT / UT2 / UT1
Training zones: Anaerobic Threshold, Upper Steady State, Lower Steady State.
Back it down
Row in reverse to move the shell backward, often for docking or aligning.
Blade
Another word for an oar. The painted end that enters the water provides propulsion.
Bow
Front of the boat and the seat closest to it. Helps with balance and may assist with steering.
Bow ball
Soft safety ball fixed to the bow tip.
Catch
The instant the blade enters the water to begin the drive.
Check
Loss of run as the boat changes direction at the front or back of the stroke.
Cox box
Amplified headset and stroke rate display used by coxswains, often with a seat sensor.
Coxswain
Athlete who steers, manages safety, and calls the race plan.
Drive
Part of the stroke when the blade is in the water and power is applied.
Erg
Indoor rowing machine used for training and testing.
Feather
Rotate the oar so the blade is parallel to the water on the recovery to reduce wind resistance.
Foot stretcher
Adjustable plate where the athlete’s shoes attach inside the boat.
Gunwale
Top edge of the shell’s sides.
Head race
Time trial format over a longer distance with staggered starts. Winner is fastest elapsed time.
Hold water
Square blades in the water to stop the boat.
Layback
Body position at the end of the drive when the rower swings past vertical.
Lightweight
Weight-limited competition category defined by regatta rules.
Oarlock
U-shaped fitting that holds the oar on the rigger.
Pair (2− or 2+)
Sweep boat with two athletes. May be coxless or coxed.
Pogie
Mitten that attaches to the oar so hands stay warm while maintaining grip.
Port and starboard
Left and right sides of the boat when facing forward. In sweep, athletes row on a set side.
Power 10
Ten strokes at higher power used to change speed or position in a race.
Quad (4x)
Sculling boat for four athletes, usually without a coxswain in scholastic events.
Rate or stroke rate (spm)
Number of strokes per minute shown on an erg or cox box.
Recovery
Part of the stroke when the blade is out of the water and the rower returns to the catch.
Rigger
Metal framework that holds the oarlock off the side of the boat.
Rudder and fin (skeg)
Under-hull components that aid steering and tracking.
Set
How level and stable the shell feels as it moves. Good set makes blades light and clean.
Shell
Another word for the boat.
Single (1x)
Sculling boat for one athlete.
Split
Time to cover 500 meters at the current pace, shown on the erg monitor.
Sprint race
Side-by-side race over a shorter straight course, commonly 1,500 to 2,000 meters.
Square
Blade position perpendicular to the water, used at the catch and through the drive.
Start sequence
Opening strokes of a sprint race, often high rate to accelerate, then a settle to race cadence.
Stern
Rear of the boat where the stroke seat sits.
Stroke seat
Seat closest to stern that sets rhythm and stroke rate for the crew.
Sweep
Discipline where each rower uses one oar. Pairs, fours, and eights are sweep boats.
Tap down
Hand action at the finish to extract the blade cleanly.
2K
2,000 meter standard test distance used widely at the collegiate and club level.
