I have a EPIC Malakai surfski with an EPIC mid wing paddle.
I paddle the same place alot.
I’m mid 60’s 5’6", 150 lb
I live in central Florida.
Two weeks ago on a windy day with some chop, I did a 10k course and then repeated it today – no chop.
I went a little slower than usual with the chop, but today did a lot slower!
Specifically 15% slower; 1.5% lower strokes per min; 15% ore strokes per mile; significant increase in heart rate even to keep that paces 105/min average max 120’s; today 121 average 140 peak.
The water is quite dark today, but it was very deep both days. Are there oils that get in water. There was no duckweed, nothing seemed to be stuck to the boat or plant material caught on the underside.
Bottom line is that I worked harder with nearly the same strokes/min, but 15% less meters/stroke, had better weather with less chop, but slower 15% . The only think I can think of is more viscosity.
