What you afraid of a fish Carl

why not just wear one of those shark cages while sailing

Back in the 90's we did alot of speed/slalom sailing at Edithburg/Coobowie,Sultana Point used to be a top spot with a long tidal sand bar don't know if it's still there.The bay at Edithburg is also great and you can sail near the bank.There are plenty of good spots we just have to find them,talk to as many fisherman as you can and i bet they would know.
