Rowing Boat Types
There are eight standard racing rowing boats: the single (1x), double (2x), pair (2-), quad (4x), coxless four (4-), coxed four (4+), eight (8+) and octuple (8x). Sweep boats have one oar per rower; sculling boats have two. The eight is the fastest and the flagship boat in rowing. Beyond the racing shells, rowing also happens in coastal boats, Cornish pilot gigs, skiffs and other fixed-seat traditional craft - all covered below.
Sculling boats (two oars per rower)
Every sculler holds one oar in each hand. The boat is rigged symmetrically. See the scull glossary entry for the technical detail.
Single scull (1x)
8.2m, 14kg minimum, no cox. The classic individual racing boat. Hardest to balance, most direct technique feedback. Olympic event.
Double scull (2x)
9.8m, 27kg minimum, no cox. The standard learn-to-scull crew boat. Olympic event in openweight and lightweight categories.
Quadruple scull (4x)
12.5m, 52kg minimum, no cox at senior level. Often abbreviated "quad". Fast crew boat. Olympic event.
Octuple scull (8x)
17m, with cox. Mostly raced at junior, masters and developmental level. Not an Olympic event but raced at some World Championships.
Sweep boats (one oar per rower)
Every rower holds one oar in both hands. The boat is rigged asymmetrically with rowers alternating bow side and stroke side down the boat.
Pair (2-)
9.8m, 27kg minimum, no cox, foot steering. The hardest two-person boat to balance and one of the most prestigious events at international rowing. Olympic event.
Coxless four (4-)
13.4m, 50kg minimum, no cox, foot steering. Often called the "straight four". Olympic event in openweight and lightweight categories.
Coxed four (4+)
13.4m, 51kg minimum, with cox. Common at junior, club and masters level. Dropped from the Olympic programme but still raced at World Championships.
Eight (8+)
19.9m, 96kg minimum, always coxed. The fastest racing boat in rowing and the flagship event. Headline race at every regatta. Olympic event in men's and women's openweight.
Coastal, traditional and fixed-seat rowing boats
Not all rowing happens in fine racing shells on flat rivers. Three other families of rowing boat are raced and rowed recreationally across the UK and beyond - see our full guide to coastal rowing boats for the open-water side of the sport.
Coastal boats (solo, double, quad)
Wider, heavier and self-bailing versions of the racing shell, built to handle waves and surf. Raced as coastal solos (C1x), doubles (C2x) and coxed quads (C4x+) under World Rowing rules. Beach sprint racing in these boats joins the Olympic programme at LA 2028.
Cornish pilot gig
A traditional 32-foot wooden (or fibreglass one-design) boat rowed by six with a cox, originally used to race pilots out to incoming ships. Gig racing is one of the fastest-growing rowing disciplines in the UK, with over 200 clubs concentrated in Cornwall, Devon and the Scillies.
Skiffs, wherries and other traditional craft
Thames skiffs, Scottish coastal St Ayles skiffs, Irish currachs and East Anglian wherries are all fixed-seat rowing boats with their own racing scenes. Skiff racing on the Thames dates back to the 1800s and still runs a full championship calendar today.
The dividing line across all of them: racing shells use a sliding seat so the legs drive the stroke, while most traditional boats use a fixed seat or thwart, putting the emphasis on the back and arms. Club rowing, coastal rowing and gig rowing each have their own governing structures, boat specs and racing calendars.

How to read the boat-class abbreviations
Boat classes are abbreviated as a number plus a letter or symbol. The number is the crew size; the letter shows the discipline and cox status:
- x after the number means sculling. So 1x is a single scull, 4x is a quadruple scull.
- + after the number means coxed. So 4+ is a coxed four, 8+ is an eight (always coxed).
- - after the number means coxless. So 2- is a coxless pair, 4- is a coxless four.
- L in front means lightweight. So LM2x is the lightweight men's double scull.
- W means women, M means men, J means junior, B means under-23.
A junior women's coxless four is JW4-. The men's lightweight double is LM2x. These abbreviations show up on regatta entry forms, race programmes and crew sheets across British Rowing, USRowing, Rowing Australia and FISA. Understanding them is the first step to entering a regatta - see the regatta glossary entry for the entry process.
What rowing boats are called
Racing rowing boats are properly called shells - a reference to the thin carbon or wooden hull. Any shell rowed with two oars per person is a scull, so "single scull" and "double scull" name both the boat and the discipline. Sweep boats are named by crew size: pair, four, eight. Rowers rarely say "rowing boat" for any of these; that phrase usually means a wooden leisure boat on a park lake.
Outside fine racing, the names multiply: gigs, skiffs, wherries, currachs, dories and dinghies are all rowed boats with distinct hull shapes and histories. In the US, "crew" refers to the sport itself (especially at school and college level), while the boats remain shells. If someone offers you a seat in their "boat", context is everything.
Why bigger boats go faster
More rowers means more power. Doubling the crew (from a single to a double, or from a four to an eight) does not double the boat's mass and drag - it adds about 80 percent more drag while doubling the power output. The result: bigger boats are faster than smaller boats of the same discipline. The eight is the fastest standard rowing boat. A men's eight at world-record pace covers 2,000m in around 5:20, averaging 22.5 km/h. The same crew rowing a four would be over 30 seconds slower.
There is a ceiling. Crew coordination becomes harder above eight rowers, the hull becomes structurally difficult to keep stiff at over 20m long, and the steering tolerances narrow. International rowing has not added boat classes above the eight (or the octuple) in nearly 100 years.
How clubs build a fleet
A typical UK or US rowing club fleet is built over decades. The order of priority for most clubs is: novice singles or wide-beam tubs first (cheap, indestructible, easy to learn in), then a couple of doubles and a coxed four for early competition, then quads, coxless fours and eights as the squad grows. Top clubs have 30 to 50 racing boats spanning every class, with senior racing shells, intermediate boats and beat-up training boats for novices.
Tracking the fleet matters because every boat has its own service history, weight, rigger setup, hull damage log and event history. Row HQ's boat booking module centralises all of this so the captain knows what is bookable, what is in for service, what was last damaged and which crew is racing it on Saturday. Compared with a laminated whiteboard in the boathouse, this is the kind of admin upgrade most clubs underestimate until they switch to it.
Boat selection for crews and regattas
Picking which boat to enter at a regatta is partly tactical (which event maximises the crew's chance of winning) and partly logistical (which boats fit on the trailer, which crews are available, which categories the federation has scheduled). Coaches working through this in crew assignment tools can model multiple line-ups and lock in the final crew sheet against the entered event.
For pathway clubs, the order of boat experience matters. Most coaches recommend starting in singles and doubles (sculling, easy to balance), then progressing to coxed boats (fours and eights with a cox to handle steering and race calls), then to coxless small boats (pair, coxless four) where the rower takes responsibility for steering and balance. Members can see their pathway in their member portal with a list of which boats they're cleared to row.
Rowing Boat Types FAQs
What are the different types of rowing boats?
There are eight standard racing rowing boats, split into two disciplines. Sculling boats (two oars per rower): single scull (1x), double scull (2x), quadruple scull (4x), and octuple scull (8x). Sweep boats (one oar per rower): pair (2-), coxless four (4-), coxed four (4+), and eight (8+). Of these, the eight is always coxed; the four exists in coxed and coxless variants; the pair, quad, double and single are coxless at senior level. The octuple is mainly raced at junior and masters level and is not an Olympic event.
What is the difference between sweep and sculling boats?
In sculling boats every rower holds two oars, one in each hand. In sweep boats every rower holds one oar in both hands and rowers alternate which side of the boat they pull on (bow side and stroke side). The boat hulls and rigging differ: sculling boats have a rigger on each side per rower; sweep boats have alternating riggers down the length. Sculling boats are typically narrower than equivalent sweep boats because the symmetric oar load needs less hull width to balance.
Which rowing boats are at the Olympics?
The Olympic rowing programme features fourteen events across seven boat classes: men's and women's single scull (1x), double scull (2x), quadruple scull (4x), pair (2-), coxless four (4-), eight (8+), and lightweight double scull (LM2x, LW2x). The coxed four (4+), coxed pair (2+) and octuple scull (8x) were dropped from the Olympic programme decades ago and now only race at World Championships or domestic level. World Rowing Championships include additional events (lightweight pairs, lightweight quads, mixed adaptive boats) not in the Olympic schedule.
How many people are in a rowing boat?
Rowing boats carry 1, 2, 4 or 8 rowers, plus optionally a coxswain. The single scull has one rower. Doubles, pairs have two rowers. Quads and fours have four rowers. The eight has eight rowers plus a coxswain. The octuple has eight rowers plus a cox. Crew sizes are fixed by international rowing rules - no five-person, six-person or seven-person racing boats exist. Coxed boats add a coxswain who steers and calls the race but does not row.
What is the fastest rowing boat?
The eight (8+) is the fastest standard rowing boat. An Olympic men's eight covers 2,000m in around 5 minutes 20 seconds at world-record pace, averaging 22.5 km/h (14 mph). The men's quad (4x) and women's eight follow closely. The single scull is the slowest standard boat - at world-record pace, women's 1x covers 2,000m in around 7 minutes 7 seconds (16.9 km/h). Bigger crews go faster because adding rowers adds more power than the additional weight and drag - but only up to a point. There is no nine-rower or sixteen-rower racing boat for that reason.
What are rowing boats called?
Racing rowing boats are called shells. Shells rowed with two oars per rower are sculls (single scull, double scull, quad). Sweep shells are named by crew size: pair, four, eight. Traditional fixed-seat rowing boats have their own names - gigs, skiffs, wherries, currachs and dories. In American English the sport is often called crew, but the boats are still shells.
What boats are used in coastal rowing?
World Rowing coastal racing uses three boat classes: the coastal solo (C1x), coastal double (C2x) and coxed coastal quad (C4x+). They are wider and heavier than flat-water shells, with self-bailing hulls designed for waves. Beach sprint racing in coastal boats debuts as an Olympic discipline at Los Angeles 2028. Separately, UK coastal communities race fixed-seat boats: Cornish pilot gigs (six rowers plus cox), St Ayles skiffs (four rowers plus cox) and Celtic longboats.
What is a coxed pair?
A coxed pair (2+) is a sweep boat for two rowers and a coxswain. It used to be an Olympic event but was dropped after the 1992 Barcelona Games. It is still raced at World Championships in some years and at some domestic regattas, but it is rare. Modern coxed pairs sometimes appear at junior or masters regattas and as a development boat for rowers learning to be steered before they can compete in the coxless pair (2-). Hull dimensions are similar to the coxless pair (9.8m, 27kg minimum) with an extra seat for the cox.
