The Difference in Equipment for Sweep and Sculling Rowing

The main difference in equipment is the oar: sweep rowers hold one long oar in both hands, and sculling rowers hold two shorter sculls, one in each hand. That single change sets the difference in rigging, boats and blade handling, while shoes, seats and clothing stay the same.

The figures below are typical ranges from Concept2’s rigging guidance and row2k’s rigging basics. Your club’s settings may sit a little outside them.

Pin measurement	Spread: 83 to 86 cm, centre of boat to pin	Span: 156 to 162 cm, pin to pin
Handle overlap	None	12 to 20 cm
Boats	2-, 2+, 4-, 4+, 8+	1x, 2x, 4x, 4x+, 8x+
Riggers per rower	One, on alternate sides	Two, one on each side

Oars and sculls

Sweep oars. You row on one side of the boat, so a crew mixes stroke side and bow side rowers. The outside hand sits at the end of the handle and the inside hand a short distance along it.

Sculls. You hold one in each hand, and the handles overlap as they pass through the middle of the drive and again on the recovery. One hand travels over the other, conventionally the left. That takes practice, and it’s why beginners often clip their knuckles for the first few outings.

Most clubs now use asymmetric blades in both disciplines, although older symmetrical blades are still around. Our guide to choosing a rowing blade compares the shapes. Treat every blade as fragile. Concept2 warns against pushing off the dock with a blade, because that causes splinters and other damage.

Rigging

This is where the two differ most, and the numbers are easy to check with a tape measure.

Sculling span runs from pin to pin across the boat. Sweep spread runs from the centre of the boat to the pin. Both set how far your hands travel and how much load you feel.

Inboard is the distance from the end of the handle to the blade-side face of the collar. More inboard makes the oar feel lighter. Concept2’s oar manual gives a starting sum for each discipline:

• Sculling: half the span plus 6 to 8 cm. With a 160 cm span, that’s 80 cm plus 6 to 8 cm, or 86 to 88 cm.
• Sweep: the spread plus 29 to 31 cm. With an 85 cm spread, that’s 114 to 116 cm.

Gate height has one key sculling detail. The left gate is set higher than the right, usually by 0.5 to 1.5 cm, so the left hand can cross over the right without the handles hitting. A sweep boat has no such offset, because the handles never overlap.

Rigging is adjusted by a coach or boatman in most clubs, so don’t change a club boat without asking. Note down any settings that suit you.

Boats

• Sweep boats: pairs, fours and eights, coxed or coxless. Eights always carry a cox. Each rower has one rigger, and the sides alternate down the boat.
• Sculling boats: singles, doubles and quads, usually coxless in club use, with a rigger on each side of every seat. Coxed quads (4x+) and octuples (8x+) exist too, mostly for juniors and crew training.

Because each sculler has a blade on each side, a double often feels more settled than a pair of the same width. A sweep crew relies on everyone balancing the boat together. A single is the smallest and most sensitive boat, so beginners usually start in a wider training single or a double or quad. Our rowing boat types guide sets out every class with its length and minimum weight.

What stays the same

• Shoes and stretchers. The same in both. Heel restraints matter in every boat, because they let your feet come free in a capsize.
• Seats and tracks. Similar across both.
• Clothing. No difference. Choose close-fitting kit that won’t snag on the handles.
• Tools. Riggers on most boats take the same double-ended 10 mm and 13 mm spanner, known as a rigger jigger. Scullers often carry their own because they adjust more of their own boat.

Common mistakes

• Taking the wrong set. Sweep oars and sculls can be mixed up in a crowded boathouse, as can sets of sculls of different lengths. Check the marking on the shaft before you carry them down.
• Setting an inboard for a different boat. Sculls moved from one boat to another may need the collar moved if the span differs. Run the sum above.
• Rowing at full power with the crew sitting out. Concept2 advises against this, because it can load the oars beyond their design strength.
• Leaving a gate open. Close and tighten it before you get in, whichever discipline you row.

Which should you choose?

Neither is better. Choose sculling if you want independence, since a single lets you row alone once you’re competent and your club allows it. Choose sweep if you enjoy crew boats. Many clubs teach sculling first because it builds blade skills, and your squad’s boats may decide it for you if you race. Either way, our 10 reasons rowing is such a good sport apply to both.
