Sandy Bay is awesome but can get a little shallow in spots at low tide, high tide its fine.
Wobiri is a bit deeper once you drag out a little bit.
Yes there will be a few turtles around, moreso at Wobiri, Sandy Bay doesn't seem to have as many in my experience.
Also the Gulf side near Budegi boat ramp is ok in the morning Easterlies, long way from Osprey though.
This was a rare NWer at Sandy Bay on a foil.
