I draw 1 metre and I wouldn't go out/in South passage on a flat calm day.
Re the passage from Southport to Moreton Bay:
With 2.8 metres draught, they will need a bloody big tide to get through the skinny bits north of Jacobs Well IME. We draw only 2.2 and need to time things for near high water
. The channel is a bit shifty but well marked in most areas, and the bottom is soft, not rocky, so the penalty for error is not too bad!
If the depth
issue prohibits usage of this route
, the most expeditious means of entry to Moreton Bay from the sea is via the Northeast Channel. This route
is viable in all but heavy conditions and saves many miles over going clear to Caloundra.
As mentioned, the passages between the islands are absolutely impassable for vessels like ours.
