ψαχνωντας παλιά πόστ κάτω στην λεωφόρο της μνήμης, βρήκα ένα πόστ που έχει μείνει ουσιαστικά ανπάντητο...
Το παραθέτω μηπως έχουν γνώση και γνώμη οι φίλοι εδώ...
I wonder if it makes sense to use a smaller blade paddle for a smaller paddler in a tandem kayak.
Fist let us analyze the forward stroke which is the 90 percent of all paddling in folders.
I suppose that we both use same area blades. As the movement must be coordinated, the forward movement of the vessel provided by the stroke of the stronger paddler, will make the movement of the weaker paddler easier in the watter.
So the contribution of the two paddlers in a coordinated stroke, will be according to each paddlers strength, no matter the area of the blade.
On the other had a smaller blade area for a weaker paddler would create less strain at the same cadence that the stronger paddler may maintain with a larger area paddle.
It can also be very helpful if the weaker paddler is paddling the vessel alone for some time...( e.g. the other paddler taking care of navigation)
A situation that may occur is that the smaller area blade paddler will increase the cadence at a pace the greater area blade paddler will not be comfortable following.
In tandem bikes we handle the difference in strength of the riders by using longer of shorter pedal shafts. ( the weaker rider gets a shorter one).
Of course in tandem bikes it is very unusual for one rider to pedal alone...
Any ideas or experiments on this?
Are my thoughts correct or I miss a point....??
