Regarding tide, sometimes it is preferable to ride at low tide.
We have places, where the longer "Reefs" are here and there, under the surface at high tide and just over at low.
Actually not a classic coral reef as we dont have such, but spots in the middle of things, suddenly low water because of a long rock/musselreefs, like underwater/surface jetty's.
When high tide you can not see where they are, and you have to ride extremely safe far away, which often gives you a very narrow strip to ride to get out/in or around, because you are very careful.
Here I prefer low tide, so I can see these and ride close, and always avoid them, eventhough the risk of a new hidden rock is higher - but we know the spot quite well
So visual direct positioning is far better, even though it is low tide
A different way wanting low tide, instead of high tide, for hydrofoiling.
