Or is it something much more hydrodynamically >subtle? A ferry in a current and a cross-wind ferry are based on the same principle: compensating sideways forces on the boat by angling to that force. But an important difference is that in a current you better lean the boat downstream, and in a cross-wind ferry it is better to lean (a bit) upwind. Ferry gliding is a more British term for ferrying, which has the misleading assumption that the work of this action is done by the current, or in this case the wind. However this is not the case, as the work has to be done the paddler. And for those who will not believe that: stop paddling in such a situation, and see what happens...

G'Day and thanks for all the ferry gliding posts, direct and back channel. I'm now comfortable with the idea that ferry gliding can be understood by vector addition of the velocity due to the current, the paddler and the wind. And that an edged kayak will tend to be affected by a component vector of the force due to paddling rather than the maximum force potentially available. Much appreciated peoples comments, All the best, PeterO *************************************************************************** PaddleWise Paddling Mailing List - Any opinions or suggestions expressed here are solely those of the writer(s).
