Remeasuring the English Channel (What Constitutes Shortest Route?)
As I've seen it, the EC is traditionally measured from Dover to Cap Gris Nez. Possibly, though, this isn't the shortest possible route. (Ooh! Philosophical discussion! )
As per the second map, I think you could get away with 0.7km* less swimming if you had no course corrections, and you got really, really, really lucky and the tide happened to land you directly on Cap Griz Nez. You'd still S-curve your way across, but you'd only complete 32.3km* of actual swimming. The rest would be free ride courtesy of the tide.
By the spirit of open water swimming, I'm thinking you'd want to declare the shortest route across the EC at 32.3km*, not 33.0km*.
Thoughts? I'm really curious about what the community thinks of this.
*All distances approximate. I'm interested in the spirit of measurement here, not the actual surveying.
