I know this is going to be a shocker to everyone, but sailors exaggerate windspeed as much or more than fisherman do the size of the one that got away. Take these two videos below. The first is from the user mendo on youtube, and is titled "Hawaii sailing in 70 knots". Yes, you read that right sailing in 70 knots. The second is from Clark Beek, and shows a video taken at anchor with clocked speeds of 70 knots.
I will leave it up to you folks to decide who is the truth teller.
