Did an interesting experiement this morning on my morning paddle, with the GPS on I was interested to see the difference in speed, if any, when I engaged the more planing part of the Pin v the displacement type front by moving more forward on the board.

The results I will say are interesting

For 1km lap on displacment hull
Max speed = 8.6 km/h
Average speed = 7.8 km/h

For 1 km lap on planing hull (and most of the other 4 km of the paddle)
Max Speed 8.5 km/h (other 4 km of the paddle max speed was between 8.2 and 8.7 km/h)
Average speed = 7.2km/h (other 4 km of the paddle average speed was between 7.2 and 7.4 km/h)

I think this aligns with the generally accepted theory that a displacement hull is not faster in a max speed sense but in efficiency through the water and average speed.

I dont know if it is psychological but in displacement hull mode the board seemed to maintain the glide longer and lose less speed when switching sides.

Any thoughts / experiences?

Hi Zimbo,
What type of board were you on? Do you have a shot?

What is the max speed the board can be paddled to in a short sprint, 100 meters or so?
What type of GPS are you using?
Your speeds were done on water like in the shots, flat & no wind?

What I do to evaluate a board is paddle an out & return set 5 k course with a Garmin 301 & use the heart rate monitor to gauge my input.
Quicker times from changing standing/trim position, fin size, nose fin, etc can be easily seen.
The heart rate monitor is the key, it's difficult to get an accurate evaluation without it, sure you can race the clock, but you might put in more one day than the next....the paddler's input has to be as uniform as possible.
The river quiver.. 20'x26" 16'x24" 14'x27".....the planning hull is not even in the race.



The sprint speed of this mother is 13k's......but we are cheating here with a flat 20'


I raced the 14' below against a mate on the 20' over 1/2k or so, the speed maintained was about 9.5 to 10k's, & was 100m ahead of the 20', (I dont think Glenn was putting in... as he knew we were going for a surf after )

even with the heart rate monitor, you would have rest in between paddles to show consistency. it has been shown overtrained or tired people/athletes heart rates are higher then their normal heart rates even though they /you could still put out a workrate

Yeah...I am aware of that, I only do 1 run on 1 day, not consecutive runs etc, or when I have had other exercise, I try to keep it as comparitive as possibe.
