Belinda will pick up the other bit later but I just wanted to get down our trip through the Narrows. This is the strip of water between the mainland and Curtis Island.
We left Gladstone marina about 0630 yesterday which was just after low tide. The tidal flow from Boat Creek (in the middle of the Narrows) goes south with the falling tide and also from there (Boat Creek) it goes North with the falling tide. By that I mean Boat Creek is in the middle where it meets.
We could have left Gladstone later and had more tide assistance but instead we left early when the tide had stopped flowing against us and headed up the channel for a couple of hours. We stopped around Black Swan Island and anchored for a couple of hours waiting for the tide to rise sufficiently.
Interesting fact, the Narrows aren't really narrow, they are however very shallow and in places dry out to 2.1m above sea level.
The projected high tide was 3.5m which means that in that one spot where it dries to 2.1m we would have a total of 1.4m of water at high tide and we draw 1.2m. Makes it pretty close.
Anyway, we up anchored at 1030 and started to tiptoe out way through. On the charts where it dries out it's displayed in green, while the areas that don't dry still stay blue.
