Rowing Boat Types
World Rowing recognises eight standard racing shells, and you will see every one of them on the Karapiro race lane during Maadi week: 1x, 2x, 2-, 4x, 4-, 4+, 8+ and 8x. Sculling crews hold two oars apiece; sweep crews hold one. The coxed eight remains the prestige boat at every regatta on the Aotearoa calendar, from Maadi Cup A finals to the senior eight at the NZ Championships. Masters quads (4x) and senior pairs (2-) sit just below it in club status. Beyond the fine racing shells, New Zealanders also row coastal boats on open water and traditional fixed-seat craft like surf boats and St Ayles skiffs - all covered further down.
Sculling shells (two oars per rower)
Sculling means two oars per athlete, one in each hand, and a rigger on both sides of every seat. Read the scull glossary entry for the rigging detail and oar geometry.
Single scull (1x)
8.2m hull, 14kg minimum, no cox. The purest test in the sport. Every wobble is yours, every stroke is feedback. Olympic event. Mahe Drysdale, training out of Karapiro, won five M1x world titles and Olympic gold in London 2012 in this boat. A new Sykes single for a Kiwi club sits around NZD 14,000 to 18,000.
Double scull (2x)
9.8m hull, 27kg minimum, no cox. The natural progression once a sculler can sit a single flat. Olympic class in openweight and lightweight. Robbie Manson and Chris Harris took the M2x world-best time at Poznan in 2017, a record that stood for years.
Quadruple scull (4x)
12.5m hull, 52kg minimum, no cox at senior level. Almost always shortened to "quad". One of the fastest shells on flat water at Lake Ruataniwha and a staple of NZ masters racing. Olympic event.
Octuple scull (8x)
17m hull, with a coxswain. Mostly a junior, schools and masters shell. It is not on the Olympic programme but does feature in some World Rowing junior events and pops up occasionally at NZ secondary schools regattas as a development boat.
Sweep shells (one oar per rower)
Sweep means one oar held in both hands, with rowers alternating bow side and stroke side along the hull. Rigging is asymmetric, and crews are typically set up as bow-pair, middle four and stern-pair.
Pair (2-)
9.8m hull, 27kg minimum, no cox, steered with a foot plate. The hardest two-person shell in rowing and arguably the most prestigious title in the sport. Hamish Bond and Eric Murray went undefeated in this class from 2009 to 2016, winning back-to-back Olympic gold in London and Rio. The Bond Cup at the NZ Championships is named in their honour.
Coxless four (4-)
13.4m hull, 50kg minimum, foot-steered. Sometimes called the "straight four". A pure crew test: no cox to manage rhythm, the stroke seat carries the calls. Olympic event in openweight and lightweight. NZ's M4- has medalled at multiple recent Olympic regattas.
Coxed four (4+)
13.4m hull, 51kg minimum, with cox. The workhorse boat for U15 and U16 categories at the Maadi Cup and the standard learn-to-sweep shell for almost every NZ secondary school programme. Off the Olympic schedule since 1992 but still raced at World Championships and across the Maadi programme.
Eight (8+)
19.9m hull, 96kg minimum, always coxed. Quickest racing shell in the sport. The A-final of the boys' and girls' 1st VIII at the Maadi Cup is the headline race of the entire Aotearoa schools season. A new Empacher 8+ runs roughly NZD 75,000 to 90,000 once it lands in a Kiwi boatshed.
Coastal, surf and fixed-seat rowing boats in NZ
Flat-water shells are only part of the picture in a country with 15,000 kilometres of coastline. Kiwis also row on open water, in the surf zone and in traditional fixed-seat boats - our guide to coastal rowing boats covers the open-water side in full.
Coastal boats (solo, double, quad)
Beamier, heavier, self-bailing cousins of the racing shell, built to punch through chop rather than skim flat water. World Rowing races them as the coastal solo (C1x), coastal double (C2x) and coxed coastal quad (C4x+). Beach sprint racing in these boats joins the Olympic programme at LA 2028, and NZ's harbours and ocean rowing crews already put these hulls through conditions Karapiro never serves up.
Surf boats and pilot gigs
The surf boat is NZ's traditional crewed rowing discipline: four rowers and a standing sweep driving a heavy open boat out through breaking waves, raced at Surf Life Saving New Zealand carnivals every summer. It fills the same cultural slot the Cornish pilot gig holds in the UK - a six-oared workboat turned racing class with a passionate club scene.
St Ayles skiffs
The St Ayles skiff is a four-oared, coxed wooden boat that communities build themselves from a kit, then race against neighbouring towns. The movement started in Scotland and has taken root in New Zealand, where an active community rowing scene builds and races these skiffs - a low-cost, all-ages entry into rowing that needs a shed and some volunteers rather than a boathouse full of carbon.
The line that divides all of these from the racing shells is the seat. Shells slide, so the legs drive the stroke; surf boats, St Ayles skiffs and most traditional craft fix the rower to a thwart and load the back and arms instead. Each discipline runs its own governing body, boat specs and calendar - and none of them should be confused with waka ama, which is paddled with a single blade, not rowed.

Reading the boat-class abbreviations
Every shell class on a Rowing NZ entry form is written as a number plus a suffix. The number is crew size; the suffix tells you the discipline and whether there is a cox:
- x means sculling. 1x is a single scull, 4x is a quad.
- + means coxed. 4+ is a coxed four, and the 8+ is always coxed.
- - means coxless. 2- is a coxless pair, 4- is a coxless four.
- L in front of the abbreviation flags a lightweight class, so LM2x is the lightweight men's double.
- W is women, M is men, J is junior (U19 in NZ), B is under-23.
Worked examples: JW4- is a junior women's coxless four (the U18 4- at the Maadi Cup), LM2x is the lightweight men's double, GirlsU15 4X+ is the under-15 girls' coxed quad. You will see these codes on Maadi Cup race programmes, NZURA Bond Cup entry sheets, Rowing NZ trial bibs and the side of every trailer hauling crews up to Karapiro. Learn them once and the whole calendar reads clearly. See the regatta glossary entry for how entries get processed through to race-day lane draws.
What rowing boats are called in NZ
The proper name for a racing rowing boat is a shell, after the thin skin of carbon (or, in older club boats, wood) that forms the hull. When the boat is rowed with two oars per person it is a scull, which is why "single scull" and "double scull" describe the boat and the discipline at once. Sweep shells are simply named by crew size: pair, four, eight. Around a Kiwi boatshed you will hear "the boat", "the shell" or just the class name - nobody who rows calls a racing shell a "rowing boat", a term that in NZ usually means a clinker dinghy tied up at a bach.
One naming line matters more in Aotearoa than anywhere else: waka ama is not rowing. The outrigger canoe is paddled, facing forward, with a single-bladed paddle - a thriving sport in its own right with its own national body, but a paddling discipline, not a rowing one. Rowing means facing backwards and levering an oar against a fixed pivot. Beyond the shells, NZ rowing vocabulary stretches to surf boats, St Ayles skiffs and coastal boats, each with its own crew layout and racing scene.
Why bigger shells go faster
Power scales with crew size, but drag scales with hull surface area, and the two grow at very different rates. Doubling the crew (going from a single to a double, or a four to an eight) roughly doubles the watts on the water while only adding about 80 percent to the drag. That is why the eight is so much faster than the four, and the four faster than the pair. World-class M8+ pace at Karapiro is comfortably inside 5:30 over 2,000m, sitting near 22.5 km/h on the boat speed read-out. The same eight athletes, splintered into four pairs, would each finish over a minute slower.
There is a hard ceiling at eight. Hull stiffness, rudder sensitivity and crew timing all break down beyond that. World Rowing has not added a shell class above the eight or octuple in close to a hundred years, and there is no realistic prospect of one. The eight is the upper limit of what a single coxswain can call and a hull can hold straight.
How NZ clubs build a racing fleet
A typical Aotearoa club fleet grows over decades. Most start with wide-beam tub pairs and a coxed novice four or two for learn-to-row, then add doubles for early sculling progression, then expand into quads, coxless fours and the senior eights that headline the racing programme. Established setups like Waikato RC at Karapiro or West End RC in Auckland carry 30 to 50 shells in active service, ranging from elite Hudson and Empacher racing hulls through to battered Sykes club boats used for novice winter mileage. The boatshed at any well-resourced NZ secondary school programme - Saint Kentigern, Christ's College, St Bede's, Hamilton Boys - runs the same hierarchy: race-day shells locked away, training shells racked at the front.
Each shell carries its own paper trail: weight, build year, rigger configuration, repair log, crew assignments and damage history. Row HQ's boat booking module pulls all of that onto one screen so the club captain can answer "what is bookable, what is in the workshop, what was last damaged and which crew has it entered at Saturday's regatta" in seconds rather than minutes. A laminated whiteboard inside the shed door does the same job until the squad passes about 40 athletes, and then it stops working overnight.
Shell selection for crews and regattas
Picking which class to enter at a regatta is part competitive judgement and part trailer arithmetic. The competitive side: which event lines up best against the rest of the field, which lineup is healthy this week, which class the crew has trained for. The logistical side: how many shells fit on the trailer, what categories Rowing NZ or the host club has scheduled, whether the cox has the right weight for a 4+ or 8+. Coaches using crew assignment tools can model three or four lineups against the entered events, lock in the final crew sheet and have it on the rowers' phones before they leave the boatshed.
The boat progression most NZ coaches follow with developing athletes runs: single and double (sculling, where balance is learned without a partner to compensate), then coxed fours and eights (a cox handles steering and rhythm calls while rowers focus purely on the stroke), then coxless small boats like the pair and coxless four (the rower takes on steering, balance and accountability). Members can see exactly which shells they are cleared in through their member portal, alongside their bow loader licence status and the rigging notes for each boat.
Rowing Boat Types FAQs
What are the different types of rowing boats?
Eight standard racing shells, split across two disciplines. Sculling shells (two oars per rower): single (1x), double (2x), quad (4x) and octuple (8x). Sweep shells (one oar per rower): pair (2-), coxless four (4-), coxed four (4+) and eight (8+). The 8+ is always coxed. The four exists in both coxed and coxless variants. The single, double, pair and quad race coxless at senior level. The octuple appears mostly at junior and masters regattas in NZ and is not on the Olympic programme.
What is the difference between sweep and sculling boats?
Sculling gives every rower two oars, one per hand, with the shell rigged symmetrically. Sweep gives every rower one oar held in both hands, with crews alternating bow side and stroke side down the boat and the rigging set up asymmetrically to match. Sculling shells run narrower than the equivalent sweep shells because a balanced two-oar load needs less hull beam to stabilise. Sculling is the discipline most NZ clubs start beginners in (the single and double in particular); sweep tends to follow once crew rhythm and timing have been trained.
Which rowing boats are at the Olympics?
Fourteen Olympic events across seven shell classes: M1x, W1x, M2x, W2x, M4x, W4x, M2-, W2-, M4-, W4-, M8+, W8+, LM2x and LW2x. The coxed four (4+), coxed pair (2+) and octuple (8x) were dropped from the Olympic schedule decades ago and now race only at World Rowing Championships or domestic regattas. New Zealand has medalled across most Olympic shell classes, with Hamish Bond and Eric Murray's undefeated 2009-2016 run in the M2- standing as the best-known sustained dominance of an Olympic boat class in Kiwi sporting history.
How many people are in a rowing boat?
Racing shells seat one, two, four or eight rowers, with a coxswain bolted on for some classes. Single: one rower. Double and pair: two. Quad and four: four. Eight: eight plus a cox. Octuple: eight plus a cox. World Rowing rules fix these numbers - there is no five-, six- or seven-person racing shell, and there never will be at international level. In a coxed boat the cox steers, calls the rate and the race plan, and does not row.
What is the fastest rowing boat?
The eight (8+) wins on raw speed. Top-end M8+ pace at Karapiro covers the 2,000m course in around 5:20, with average boat speed near 22.5 km/h (about 14 mph). The men's quad and women's eight are not far behind. At the other end the single scull is the slowest standard shell, with the W1x world-best sitting near 7:07 over 2,000m (around 16.9 km/h). Bigger crews go faster because each extra rower adds more power than they add weight or drag, but the relationship breaks down past eight - which is why the racing taxonomy stops where it does.
What are rowing boats called?
Racing rowing boats are shells. A shell rowed with two oars per person is a scull - single scull, double scull, quad. Sweep shells take their names from crew size: pair, four, eight. NZ's fixed-seat rowing boats carry their own names, chiefly the surf boat and the St Ayles skiff. Note that waka ama is an outrigger canoe and is paddled, not rowed - it belongs to paddling, not rowing, despite often sharing the same stretch of water.
What boats are used in coastal rowing?
World Rowing coastal racing runs three classes: the coastal solo (C1x), coastal double (C2x) and coxed coastal quad (C4x+). All are wider and heavier than flat-water shells, with self-bailing hulls built for swell and surf. Beach sprint racing in coastal boats becomes an Olympic discipline at Los Angeles 2028, giving open-water rowing its first Games slot. NZ crews also row the ocean and race fixed-seat boats on salt water - surf boats at Surf Life Saving New Zealand carnivals and St Ayles skiffs in the community rowing scene.
What is a coxed pair?
A coxed pair (2+) is a sweep shell carrying two rowers and a coxswain. It was an Olympic class until the 1992 Barcelona Games, then dropped from the programme. World Rowing still runs it at the World Championships in some years, and it appears occasionally at NZ masters and junior regattas as a development boat - a stepping stone for sweep rowers learning to balance and time a small shell before they move into the coxless pair (2-). Hull dimensions match the coxless pair (9.8m, 27kg minimum) with an extra seat and rudder yoke for the cox.
