This will be too late for Steve's trip but I would caution that swimming from Spring Bay to the Baths can be tricky as there can be a strong current there, esp. if the seas are up. Note: can be a steep drop off at Spring Bay, Baths and Devils Bay which is why dingying in at the Baths is not possible (there is a line across the water parallel to the beach, and a dingy line strung off to the right as you
approach the parallel line) And I cannot tell you the number of times we have watched the dumping of people into the water at Spring Bay when they have tried to do the same there...not worth the risk of injury from falling, boat flipping or getting hit by the boat.
