Grade Comparison Table


For additional information on the safety of DWS routes I have adapted the American (Yosemite Decimal System) rating on protection as follows with the equivalent Dorset DWS grades in brackets:

  • No suffix – deep enough water, no obstacles. Refer to route description for recommended tide state. Some routes not safe at low tide (S0).
  • R – shallow water and/or underwater obstacles. Usually safe to make a controlled jump and entry but not safe to fall uncontrolled (S1/2).
  • X – not safe to fall. Injury guaranteed (S3).
