I'm new to this forum and not sure that I'm posting
in the right place.
Just been up to Lizard Island and can advise depth
of channel into Yorkey's Knob marina 1.0m LAT. Channel into Port Douglas 1.5m LAT and marina VERY shallow but manager very helpful; will put small boats with a bit of draught into super-yacht berths. Cooktown entrance channel about as last NTM and depth
across bar into inner anchorage about 1.0m LAT as usual.
