  • Good points. The 4mph was the average mph from a sports watch using a kayak, so i assume it's 'land 4mph'.

    I feel I'm missing something also, Just tickeled my curiosity.

    Using GPS, presumably, in which case the frame of reference is terra firma. If you're doing a ground speed of 4mph directly into a 6kt counterflow, your water speed is 9.5kt
