Hi Coutta, I came in 2 hours after low on Saturday and would've like a bit more water, it was 0.6m picking the best channel I could see, which is the minimum for my boat. Coming into Kaituna when its like this I get onto a healthy plane and as I cross the bar trim the motor up to about 7-8 degrees on my gauges which helps, I get a bit of ventilation but stay on the plane. Going out across the cut for me is less forgiving depending on swell.
I have been applying the 2 hours each side of low tide for a long time and its pretty reliable, neap tides help especially if its 0.5 to 0.6 m low, always there's exceptions to any rule like this autumn when the river angle towards the Mount from all the easterlies.
I haven't been able to find the Maketu Coastguard cam for a while which is nice to check the day before around the lower tides, then there is the Ports A Buoy website for swell size before you go.
If you go mid tide with no swell its very safe, just pause to watch even tiny waves break and like the advert on TV about rips when swimming look for where the waves aren't breaking.
