Yes. Not all the islands have such anchorages
. Bora does. I think Huahine does not. Raiatea/Tahaa do, but we did not use them there.
You anchor as you find fit.
You want to avoid getting your (----) on the coral
, the shallow, or the beach, if/when the wind
drops off at night or when it reverses. E.g. second anchor.
The white water
is shallow. You can only go there in a shallow mono or else in a cat. The sand may be very thin, it is lose and gives no holding. There is a shelf underneath and you may drag in a heavy puff. A heavy anchor with the biggest flukes area and plenty of chain give you more time to react.
Basically you go, you explore and you anchor as you like. Avoid coral
heads and wind shift problems. It is not too tidal and you can often reverse under power or sail when you touch. You will have one person on the spreaders or on the bow HIGH. Quality polarized glasses and the sun high and not ahead.
Remember you may have to re-anchor or leave in the rain and dark - anchor so that you have at least one easy escape path to an alternative easy anchorage.
