I used the white water paddle to go as fast as I could for 3 miles which took me 40 minutes on Lake Crabtree. There was some wind gusting to maybe 10 miles an hour. I don't think that is any faster than I go with the Lumpy Greenland paddle and it was a lot of strain on my left shoulder. My top speed was 5.7 miles an hour. I think the seat height is fine but I want to move the seat position forward a bit so the stern does not drag when I'm trying to go fast.
