This should probably go to the Design BB, but I checked my calcs last night (using Matt Broze's drag prediction spreadsheet based on John Winter's method). The differences between the two designs slowly grow as speed increases.
Predictions for 6 knots:
17.5' kayak: 5.29 residual + 5.27 frictional = 10.56 lb total resistance
19' kayak: 4.80 residual + 5.47 frictional = 10.27 lb total resistance
Not enough difference for the paddler to notice, but would probably
make a difference over a 20 mile race course.
