I disagree - the technique is the same
Back to that rough water / calm water recovery subject...
I have to agree with Darren on this, especially his analogy about crampons and glacier travel. Not only is rough water recovery so much more difficult but there is a HUGE difference in the mental state of a person when in rough water compared to calm water, especially in the state of mind of an inexperienced paddler.
The unexpected need for recovery techniques in calm water
might not throw an inexperienced paddler into panic mode but it will most likely get their heart rate up a little bit temporarily. Hopefully it doesn't get too high for any of us, no matter what our skill level is.
However the unexpected need to practice recovery techniques on
rough waters will definitely spike the heart rate of paddler with little to no experience on rough water. They may panic. This can lead to unclear thinking and the loss of good judgement. Time is critical in these situations and a paddler must be confident in his/her ability to return safely and make efficient decisions . The word of the day here is "confidence." If you might be paddling in rough seas or get caught in rough seas, you must be confident in your ability to paddle in that environment.
I can remember Coldfeet and I used to paddle every Wednesday evening (btw, we need to start that up again CF) at different areas along the north shore here on Long Island. We would try to make a point of occasionally practicing our recovery techniques. This was a great boost for our confidence and enabled us to extend our trips each time.
