sunman60, re this sentence

“Boatyball - is a 7am scrum at Cooper Is and Great Harbour, the others are less pressurised; those two are a shame but you can drop the anchor in both if you're ok doing that.”

You should not anchor at Cooper Island. The grass is eaten by the sea turtles. Anchor there and you may harm the turtles.

There are signs in the dock advising not to anchor.

I believe it may even be illegal to anchor there.

The holding is terrible and the risk of dragging is high,

I hope this helps.
