Land speed is not equal to water speed because of current, therefore compare shell versus water speeds. The boat sits and moves with the water regardless.
How to measure speed
- use a stop watch on a marked course and flat water
- GPS – convenient but remember this is land speed not water speed
- Impeller and speed meter in the boat
- stroke rate and speed data
- heart rate and speed
- set target splits / wattages
- note wind speeds
- athletes are responsible for split and quality of their rowing
- measure wind speed and direction
- measure the same way every time for accurate comparison
- similar conditions give better comparisons
The NK speed coach only has 1500 measureing points i.e.one per meter for 1500 meters. You can't get a full race data out of a speed coach.
You can use speed measuring equipment to assess your boa, rigging and oars and compare them to other makes.
