The shelf starts at about 3.1m in the back of the bay, but it's usually best to walk the 10 minutes to the launch spot as the back of the bay is nasty ooze muck.
I added a photo of the shelf to

Keep in mind that the beach debris is ever changing at Iona so you might arrive to find the launch covered in logs.
