My average speed over ground, as measured by my GPS, for any given year's cruising on the Cheasapeake was 5.6 kts. This was a combination of sailing in varied wind conditions and motoring. When motoring, I got into the habit of setting the rpms at "what felt right" for the boat.
I had never heard of "Natural Boatspeed". Using the formula, the Natural Boatspeed for my boat is 5.6 kts. A coincidence??? It looks to me like we were "in the goove".
