What is a Rigger in Rowing?

Definition

A rigger is the outrigger arm bolted to the gunwale of a rowing shell. It projects 70 to 90cm outboard - the exact distance depends on the rigging spec for the boat class - placing the pin (the oar's pivot point) well clear of the hull. That outboard placement is the whole point: it converts a comfortable horizontal pull at the handle into a much shorter and much more forceful push against the water at the blade end.

Around a Canadian boathouse, "rigger" and "rig" are used interchangeably ("port rig is bent on the bow pair", "check the rig on seat four"). The verbs "to rig" and "to derig" mean attaching the rigger to the hull and removing it. Almost every racing shell gets derigged for road transport - the projecting arms would otherwise prevent boats from stacking on a trailer headed for Brentwood or the Henley.

Rigger anatomy

A rigger has four working components, each of which is adjustable or replaceable on the bank:

• Pin: the vertical metal post fixed to the rigger arm. The swivel turns on it. Pins have a polished stainless surface and carry the pitch adjustment - the lean of the pin fore-and-aft and side-to-side - that governs the blade angle through the catch and the finish.
• Swivel (oarlock): the U-shaped plastic piece that cradles the oar shaft. It rotates around the pin and carries a hinged top gate that closes over the oar to hold it in place. The swivel is where the rower's force is transferred from the oar onto the rigger and into the hull.
• Sleeve: the plastic collar bonded around the oar shaft that contacts the inside face of the swivel. Sleeves belong to the oar rather than the rigger, and must match the swivel diameter. Concept2 Macon, Concept2 Smoothie and Croker sleeves are the common types in Canadian club sheds.
• Button: the adjustable plastic stop on the oar shaft that bears against the inboard face of the swivel. It holds the oar in place laterally and sets the inboard length - the portion of the oar on the rower's side of the pin, which determines how much of the oar works as a lever and how much sweeps through the water.

Rigger materials

Aluminium runs nearly every club fleet in Canada - durable through cold winters, forgiving of dock collisions, and straightforward to repair on the bank when a bow pair manages to wedge a rigger against a piling. Anodising adds protection for clubs that train near salt water on the BC coast or against tidal stretches inland. A bent aluminium rigger usually goes back to true with a vice, a mallet and a patient volunteer; a cracked carbon rigger does not.

Carbon fibre rigs sit on elite sculling shells where the weight saving meaningfully changes how the hull rolls under load - a single scull is acutely sensitive to weight above the waterline. Hudson Boatworks, who build a substantial fraction of the racing shells in Canadian boathouses out of their Picton, ON factory, run aluminium arms on their production sweep boats and carbon arms on their top-end singles and doubles. Empacher and Filippi follow the same convention. The split reflects the priorities of each boat class rather than a quality hierarchy.

Rigging adjustments

Four parameters define a rig and shape every stroke. The technician or coach sets them, and the boathouse should record them - because the cost of losing a known-good setup and finding it again through trial and error is measured in weeks of squad time:

• Height: the vertical distance from the seat to the swivel. Too low and the rower's hands collide with the gunwale at the finish; too high and the catch becomes awkward to land cleanly. Standard sweep heights run 16-18cm, sculling heights 14-16cm.
• Span (sculling) / Spread (sweep): pin-to-pin distance for sculling, pin-to-centreline for sweep. This is the lever-arm and arc setting. Standard sweep spread sits at 84-86cm; standard sculling span at 158-160cm. Wider settings ease the load and shorten the arc; narrower settings load the catch and lengthen it.
• Pitch: the lean of the pin in two planes. Stern pitch (the lean toward the stern of the boat) is typically 4-6 degrees and controls how the blade releases at the finish. Lateral pitch (the lean toward the rower) is typically 0-1 degrees and governs how the spoon enters at the catch. Wrong pitch makes the blade plane during the drive or dive at the catch.
• Pin work / Foot stretcher position: the fore-aft position of the pin and the stretcher together fix where the rower sits relative to the catch and finish positions. Sliding the stretcher toward the bow gives more leg compression at the front stop - a routine adjustment when boats are shared across athletes of different heights.

Rigging adjustments cascade. Move span and height usually needs revisiting; alter pitch and the effective arc can shift slightly. Most clubs keep a per-boat rigging book recording the current numbers, so a technician can return to a baseline if an experimental setting does not pay off in race conditions.

Rigger maintenance

Rigger maintenance wins no glamour awards but matters more than rowers acknowledge. Grease the pins every few months so the swivel rotates without resistance. Check every bolt securing the rigger to the hull before each outing - loose riggers shift under load and end up bent or ripped clean off. A loose pin is the single most common reason coaches spend three sessions trying to fix a blade-angle problem with technique before someone thinks to check the hardware.

Swivels and sleeves wear with use and need replacing once grooves appear or the oar develops slop in the lock. Most Canadian clubs put one experienced member in charge as the rigger technician and keep a logbook of work done per boat. Boat maintenance tracking in the admin dashboard lets that technician record rigger straightened, swivel replaced, button reset, pin re-pitched - so the maintenance history lives in one place rather than buried across club WhatsApp threads and a paper notebook in the boathouse.

Common rigging-related issues

Most technique problems that suddenly appear partway through the season turn out to be rigging issues, not athlete problems:

• Oar slipping in the swivel: button has drifted or sleeve has grooved. Tighten or replace before the next outing - slipping mid-stroke is genuinely dangerous on the water.
• Blade angling off at the catch: pitch has moved, usually because the pin bolt has loosened over the season. A pitch meter check on the bank pinpoints it in under a minute.
• Crew rolling to one side: span or spread is asymmetric across the two sides of the boat, often because a rigger has been bent in a collision and not properly straightened. Measure both sides; if they differ by more than 1cm, the rigger goes back to the technician before the boat goes back on the water.
