Rower's Guide to USRowing Masters Rowing (21+) 2026

Under Rules of Rowing 4-104.1(d)(2)-(3):

• The category comes from the average age of the rowers, rounded down to a whole number.
• Each rower's age is their age on December 31 of the current year.
• The coxswain's age doesn't count.
• Individual rowers don't have to fall inside the category, as long as every rower is a Master and the crew's average fits.
• A crew can race in a younger category than its average, but never an older one.

Example: a four whose rowers will be 38, 45, 52 and 61 on December 31 averages 49.0, which is category C (43-49). That crew could also enter B, A or AA, but not D.

When a Masters event uses time handicaps, each crew's handicap in seconds is subtracted from its actual time, and the adjusted times decide the result (Rules of Rowing 4-104.1(d)(6)).

The formula (based on a 1,000 m course):

Handicap (seconds) = (crew average age − 27)² × Z

• Use the crew's average age, rounded down (59.8 becomes 59). The coxswain isn't counted.
• Age 27 and under gets no handicap, and the AA category (21-26) has no handicaps at all.
• For other distances, the handicap is scaled in proportion (for example, doubled for 2,000 m).
• Above 85, the published table adds a fixed amount for each extra year.

Sample values from the official table (seconds, 1,000 m):

Example: a 1x sculler aged 50 who finishes 1,000 m in 4:30.0 has an adjusted time of 4:16.8.

No age requirement. A Masters crew must be made up entirely of Masters rowers, but the coxswain doesn't have to be a Master and can cox any Masters event regardless of age (4-104.1(d), 4-103(f)). The coxswain's age isn't counted in the crew's average.

Any sex. A coxswain of any sex can cox men's, women's or mixed crews (4-105).

Minimum weight (4-105.1):

A coxswain under the minimum carries deadweight, placed as close to their torso as possible and kept in the boat for the whole race. If the deadweight isn't in the boat at the finish, the crew isn't placed. Coxswains weigh in once a day, in racing uniform without shoes. Not weighing in at all makes the coxswain ineligible.

Yes, at any USRowing-registered regatta (Rules of Rowing 5-201 and 5-203):

• Every competitor, rowers and coxswains, must be an individual USRowing member. Foreign competitors can instead belong to their own national federation.
• Every competitor must have a signed waiver on file with USRowing.
• Entries list your name, USRowing membership number and its expiry date, plus your club affiliation if it's different from the entering club.
• You represent one club per regatta.
• If you're not affiliated with a club, you can race as "Unaffiliated" in a single or as part of a composite crew.
• A composite crew mixes rowers from more than one club (or unaffiliated rowers). It can't earn team points or trophies.
• Race under your own name. A false name or ID means disqualification.

The organizing committee sets the entry method, deadlines and fees for each regatta.

These are skill classes (Rules of Rowing 4-104.2), set separately for sweep and sculling:

• Intermediate: anyone who hasn't advanced to Senior or Elite.
• Senior: has won an Intermediate or Senior 2,000 m event at the USRowing National Championship regatta or the Royal Canadian Henley Regatta.
• Elite: has been on the USRowing (or any country's) Senior National Team, including as a spare, or medaled at the U23 World Championships in that category. An Elite sweep rower is automatically Senior for sculling, and vice versa. Anyone who isn't an amateur is treated as Elite for all events.

Where you can race: you can move up a skill class but not down (4-103(a)). An Intermediate can enter Senior or Elite events; a Senior can't enter Intermediate events.

• Masters events are classified by age, not skill, so your skill class never affects your Masters eligibility.
• Masters and Youth results don't change your skill class.
• Any change of class takes effect on January 1 after the year of competition.

Under Rules of Rowing 4-104.3, no rower in a lightweight crew (including a single) can weigh more than:

The coxswain isn't counted, and any coxswain who otherwise meets the rules can cox a lightweight crew. Any event that isn't lightweight is "open" weight.

Weigh-in (4-106):

• You're weighed in racing uniform (covering the torso), without shoes.
• Lightweights weigh in once a day, in the weigh-in window for their first lightweight race that day. If racing is rescheduled and an adjusted window is created, you can use either window, but not both.
• You get one attempt. If you're within 1.0 lb of the limit, you get one re-weigh in the same window. More than 1.0 lb over on the first weigh means you can't race the event.
• Miss the window and you can't race.

Skill class doesn't depend on weight: Intermediate, Senior or Elite status applies to both open and lightweight events.

Under Rules of Rowing 4-103(h), a mixed crew must be made up of:

• 50% rowers who are qualified to compete in the women's category, and
• 50% rowers of any sex

The coxswain isn't counted. So a mixed eight has at least four rowers eligible for women's events, and a mixed double has at least one.

Related rules:

• A rower assigned female at birth can compete in any event. A rower assigned male at birth can't compete in women's events (4-103(h)). USRowing's full Gender Identity policy is in its CEO Policy Manual.
• Coxswains are exempt and can cox any event. The minimum coxswain weight for a mixed crew is 120 lb (4-105.1).
• In a Masters mixed event, every rower must be a Master, and the crew's age category comes from the average age of the rowers.

Yes, within limits (Rules of Rowing 5-206 and 5-207):

• After entries close, a crew other than a single can replace up to half its rowers plus the coxswain. The regatta can refuse substitutions not submitted in writing at least one hour before the crew's first race in that event.
• After the crew's first race in an event, the lineup is locked for the rest of that event, except for sudden illness or injury.
• Serious, sudden illness or injury: with the organizing committee's approval, that rower can be replaced at any time before the event finishes, and it doesn't count toward the half-crew limit. A health professional's certificate is normally required.
• Singles (1x): substitution only for serious, sudden illness, and only before the first race of the event.
• The substitute must be eligible in their own right. In a Masters event, they must be a Master, and the new lineup's average age must still be at least the lower limit of the age category entered. A crew can race in a younger category, never an older one.
• A composite crew stays composite even after substitutions.

Rules of Rowing 2-602 sets out five penalties. Officials can impose them without anyone filing a protest, and a penalty on a crew applies to every member of it.

Common triggers:

• Not being attached to the start 2 minutes before the scheduled time can bring a warning, and not being there by the scheduled time can bring exclusion (2-301).
• Breaking the traffic pattern or operating unsafely (2-205). The penalty applies to the crew's next race.
• Receiving outside coaching or advice during a race. Shouting with the unaided voice from shore is allowed (2-409).
• Unsportsmanlike conduct (2-410).

Head races are covered by Article VIII of the Rules of Rowing, on top of the general rules:

• Start: a crew that doesn't appear within the time set in the local regatta rules may be excluded. Crews must keep their place in the starting order, keep the right interval, and stay in the chute approaching the start. Otherwise they can be delayed, moved to the end of the order, penalized or excluded. Yield to crews being called up by the Marshal or Starter.
• Bow numbers: the organizers can require a bow number on the boat, a number on the bow seat's back, or both.
• During the race: if a rower is ejected or falls out, the crew must stop and stay with them until everyone is safely out of the water. A crew being excluded or disqualified is shown a white flag and told "Stop!"
• After the finish: keep rowing at least 100 meters so you don't block crews still finishing.
• Results: finish order is by elapsed time after any time penalties.
• Penalties: the organizers can set time penalties in the local regatta rules, added to your elapsed time. Officials can also give time penalties for anything that would earn a warning or false start in side-by-side racing. Exclusion and disqualification also apply.

In Masters events, age handicaps are subtracted from your actual time when the regatta uses them.

USRowing's Safety Guidelines recommend not launching when:

• Lightning or thunder: you see lightning, hear thunder or see skies darkening fast. If you're already out, head for the nearest shore immediately. If the storm reaches you, land, get out of the boat and wait. Don't handle boats or riggers, or load a trailer, during the storm.
• Fog: visibility is under 100 yards. If fog rolls in while you're out, slow down, sound a horn or whistle, and follow the shore back.
• High wind or rough water: waves or wind make the boat hard to steer or likely to swamp. If wind comes up suddenly, go back if it's safe, or land and wait.
• Darkness: you don't have proper lights. Boats need a red light to port and a green light to starboard at the bow, plus a white stern light, and should row only on familiar water.
• Tides and currents: tidal conditions are extreme.

Cold: hypothermia is a risk when water is below 80°F and very dangerous below 50°F. When the air is below 40°F or the water is below 50°F, a launch should stay within 100 yards of every shell. Some clubs stop all rowing in those conditions.

Heat: hydrate before and during the row, avoid midday sessions, wear light moisture-wicking clothing, a hat and sunscreen. Train early or late when temperatures above 90°F are expected.

Clubs set their own limits for their waterway on top of these, and they can be stricter.

USRowing's Safety Guidelines say:

Before you row

• Pass your club's swim test: at minimum, float and/or tread water for 10 minutes and put on a life jacket while floating. If you can't swim, wear a PFD in the shell at all times.
• Be able to pass a flip test: take the single off the rack, launch, turn, capsize, climb back in, return to the dock and rack the boat.
• Sign out in the club logbook (date, launch time, boat, your name, expected return) and sign back in afterward.
• Check that heel ties are attached and 3 inches long, rigging nuts are tight, and the bowball is secure.
• Carry a PFD in the boat whenever you row without a coach, and a phone in a waterproof case.
• Use the buddy system if no coach is out.

If you flip

• Stay with the boat. Shells float even when full of water. Don't swim away, even if you're a strong swimmer.
• Re-enter if you can, using a buddy's boat or a launch to steady the shell.
• If you can't get back in, lie on the stern and paddle the shell to shore, or lie on the stern deck of a buddy's boat. Cold water can take away muscle control very quickly.
• Body heat is lost about 25 times faster in water, so get out of the water as soon as you can.
