Check out humbers by yourself: on 1 kilometer course, gold medalist in latest olimpics was doing just a tad more than 10 (ten) knots...

I have paddled with several friends at little more than 4 knots for the Vogalonga in Venice, three times this year, and it is a 32 miles course. Newcomers were able to do the same.

I'm quite happy with sea kayaker magazine, but I speak out of my own experience. I have found out that the average formula for displacement hulls , that is speed in knots= 1.34 * square root of lwl in feet, does not apply to kayaks, just as much as it does not apply to catamarans or other slender hulls in which finesse coefficient is close to 1:10. IN kayaking, the constant 1.34 is more likely to be 1.38, according to my measurements.

However, the patuxent is sold for a 6 knots speed, that is why I came in with my comment.

I do not bike, neither I see the link in between.

Speed and hate do not matter to me. Curiosity, experience and direct verification of claims do.
