The software
There's always software.
I'm always curious to see where I've been, how far I went, and how
fast I was going when I caught that boat wake. It really helps to see
it mapped out. It's hard to tell the difference between the short
sprint and the strong current by just looking at GPS data. The map
makes it clear.

The track is color coded based on the speed. The red X's indicate the
point of maximum speed. The scale lists the speed in knots, mph, and
the percentage of the trip done at that speed. (In the above example,
I was going between 3 and 4 kts for a majority of the trip.)
The software also generates a textual output that breaks down the trip
by distance.

On this trip, I paddled 10.32nm at an average speed of 2.49kts.
3.18kts was the average speed while actually moving. On this trip, I
stopped for about 20 minutes to visit nature and eat lunch. This
reduced my overall average speed from 3.18kts to 2.48kts.
