Generally we don’t recommend mixing kayaks and SUPs on the same tour as the SUPs are slower on average – even when the SUP is paddled in kayak mode (Seat and double-ended paddle). Obviously a super-fit SUP paddler could easily keep up with or out run a less-fit kayaker; given the same general fitness level the kayaker with usually out pace a SUP paddler.
Exceptions would be:
– A trip where paddling speed is not a consideration and the group is willing to stay together
– A demo trip where you don’t plan to paddle far from the launch point while trying out the watercraft.
