One can determine the speed of the canoe mathematically by timing marks (bubbles or objects in the water) moving past two points (distance in feet) on the canoe
The mathematical formula for speed in knots is: Distance (converted to nautical miles) ÷ time (converted to hours) = Knots (nautical miles per hour)
Example: Lets say you have a 20 ft canoe
If an object moves 20 feet point to point in 3 seconds you can determine your speed (nautical miles per hr) by pluging the numbers into the formula
1. convert feet to nautical miles: 20 feet = .0033 nautical miles (20 divided by 6077 feet per nautical mile).
2. convert the seconds into hours: 3 seconds = .0008 hours (3 divided by 3600 seconds per hour).
3. divide the distance (.0033 nautical miles) by the time (.0008 hours) to get the speed (4.125 knots).per hour.
If you mantain that pace non stop over a 8hr day you could travel (4.125 x 8 = 33miles per day)
Good Luck stay safe and wear your lifevest
