ACA Paddling Techniques & Skills 3

Question 1

What is the key biomechanical principle behind an efficient forward paddle stroke?

Accepted Answer

Rotating the torso to engage core and large back muscles

Answer

Torso rotation engages the powerful core and back muscles, reducing arm fatigue and generating more powerful, sustained strokes.

Question 2

During an ACA skills assessment, a paddler consistently slips their blade through the water during the catch phase. What should the instructor diagnose?

Accepted Answer

Blade is not fully submerged, causing a flutter or slip

Answer

A slipping or fluttering blade at the catch means it is not fully buried before the power phase begins, wasting effort and reducing efficiency.

Question 3

Which type of rudder stroke is best suited for maintaining a straight course in a following sea without losing speed?

Accepted Answer

Stern rudder

Answer

The stern rudder acts as a passive steering correction at the end of a stroke, allowing the paddler to track straight with minimal speed loss.

Question 4

A student struggles to hold a ferry angle in moving water. What is the most likely cause?

Accepted Answer

Not maintaining a consistent angle relative to the current

Answer

A successful ferry requires holding a precise upstream angle; letting the angle collapse allows the current to spin the boat downstream.

Question 5

What is the function of the Duffek (bow draw) stroke in whitewater kayaking?

Accepted Answer

To carve a sharp turn toward the paddle side while carrying momentum

Answer

The Duffek places the blade forward and out to the side; the paddler plants it like a pivot point and the boat swings toward it using existing momentum.
