James coaches open water and technical skills in the sea on the South Coast near Chichester.
Contrary to what you may have heard or read you do not need to and should not swim "differently" in open water.  You do need to remain relaxed and be able to absorb whatever conditions the sea.  
We work first and foremost on understanding how to stay safe when swimming in the sea and in any open water environment.  
We also cover specific open water skills like sighting and how to cope when conditions are not flat calm.
Plus the fundamentals of a good relaxed stroke.
But don't worry you don't need to learn a new special way of swimming, just how to adapt your stroke to the conditions.
