The bottom was visible when I dropped anchor at Yeppoon -- not something which had occurred upon my yacht before. The depth sounder assured me that I had anchored in three metres, while my eyes swore otherwise.
Even more disconcerting is looking down as you are sailing along and you see the unmistakeable ripple of the seabed. I made a practice of not looking down, especially when I knew what would be there.
Middle Percy Island's West Bay had a clear anchorage; my father could see his anchor lines intertwining with a nearby yacht's at one point and I could clearly see reefs. Coming in closer to rivers and pollution, however, and none of that is possible. I rather doubt most people know what it is like to see the bottom, especially if they hang around the murky waters that constitute the likes of Pioneer Bay.
Perhaps that would be why the caretakers of Middle Percy were living there. One chap we certainly knew his reasons -- he told us in exhaustive detail -- but one can only conjecture for the others.
( A long way from civilisation. )
