In rowing, wash (also called backwash) refers to the turbulent, moving water created by a boat as it travels. Understanding wash is crucial because it acts like an invisible obstacle for other rowers.
There are two main types of wash you will encounter:
1. The Puddles
Every time a rower finishes a stroke and pulls their blade out of the water, they leave behind a swirling “puddle.”
- Active Effect: These puddles contain energy. If you row directly into the puddles of the boat in front of you, your oars will feel unstable. The water “breaks” under your blade, making it harder to get a clean grip.
2. The Wake (The V-Shape)
As the boat’s hull cuts through the river, it pushes water out to the sides, creating a V-shaped wave that spreads behind the boat.
- Active Effect: This wave is the most dangerous part of the wash. If another boat rows through this wake, the moving water will rock their shell side-to-side. This ruins their balance and slows them down significantly.
How Wash Affects Racing
In a race, wash is a tactical weapon and a major disadvantage:
- “Washing Out” an Opponent: If a fast boat gets ahead of a slower boat, the leader’s wake hits the following boat. The following boat now has to row through “dirty water,” which is bumpy and unpredictable.
- Steering for Clean Water: Coxswains try to steer their boats into “clean water” (calm, undisturbed water) to ensure the rowers can get maximum power from every stroke.
- The “Wash Shadow”: On windy days, a boat might actually try to stay close to a wall or another boat to hide from the wind, but they must be careful not to get trapped in the wash.
Simple Summary
Wash is “dirty” or “broken” water. It makes the boat wobble, causes the oars to slip, and makes the crew work much harder to stay balanced. Rowers always prefer flat, clean water because it allows the boat to glide efficiently.
