Paddle length and stroke efficiency
Paddle length depends mostly on kayak width and your height; wider boats need longer paddles (REI paddle sizing). Try our paddle length guide.
In a study of sprint kayakers, stroke mechanics and trunk movement were linked to boat speed (Brown et al., 2023, Journal of Human Kinetics). Recreational guides teach rotating your torso rather than pulling only with your arms (ACA).
