Lindyl Whetstone cadence 70 spm 80 spm avg sp 4.6 mph 5.3 mph max sp 5.9 6.1<<<<<<<<<<<< I think the reason for the difference in speed is pretty clear 7/8=.875, 4.6/5.3=.868. It looks like each stroke was moving the kayak just about the same distance (which would be expected for paddles of about the same length. For some reason you took more strokes with the Whetstone though. Was it lighter or had lighter weight blades even if the same weight? Possibly with the shorter blade you were not having to bury it as deep (takes time) to completely submerge the blade or possibly you were using some energy to push the throat area of the longer blade forward in the water due to the pivot point being below the surface and that slowed the stroke rate. Does anyone have any other ideas of why the stroke rate might have been higher with the Whetstone paddle than the Lendahl.
