Most of our tour participants are already rowers. We can accommodate the occasional non-rowing partner if they wish to cox the boat for the whole trip, and depending on weather, water and time available we can usually give them some time in a rowing seat also to teach them the basics.
BUT the rows are usually in the region of 20 km per day, which is a very long way for a non-rower. You need to have hands conditioned for rowing and some reasonable fitness to make it pleasurable!
