I'm sure there are exceptions, but I understand deploying an anchor is popular among boaties when they want to go to sleep at night and don't want their boat to drift onto rocks, bang into other boats or drift way out to sea while they are asleep.

 

Are you being deliberately obtuse?

Giving this some thought, and now that we know caulerpa is at Rakino / Woody Bay, which is one of my go to / fav anchorages, would I anchor on caulerpa if I knew it was there - no.

Not in the foreseable future, if I could avoid it.

Normally in Woody Bay I can see the bottom, and it is clear sand. I've dove on it last year (had fishing line around the prop) and there was no caulerpa in the anchorage. I went spear fishing along the reef on the south side, very good current and productive fishing, did not see anything like caulerpa then.

Whilst saying I'd avoid it if I can, it is apparent there is going to be a point in the not too distant future where it is going to be very hard to avoid anchoring on it. In which case I shall be taking the utmost care to check my anchor and chain (which I do already, as I have one of those low-tech boats where I need to work the anchor winch at the bow, watching the anchor and chain come up, as opposed to a remote cockpit jobby.

3 years ago?  the cat is out is well and truly of the bag and probably riding the horse that bolted

I don't think that means it was detected in 2021. Though I agree it's odd on the map.

For reference, here's Waiheke

Oh and apparently the mokohinaus too

Does kinda seem like it must be everywhere if it's at the mokes.

I'll bet you a good bottle of whiskey it was at the Mokes first, it's come down on the East Auckland current from offshore, and it has spread from the Mokes to all points South. Noting it was found at the Barrier and the Mercs first, and first findings tend to be where there is higher foot-traffic, so to speak, as in people to actually find it.

Noting it is naturally occurring in large parts of the Pacific and Australia. All you need is one of those La Nina years to set up the ocean currents and water temp, and hay presto - magic - killer algae.

Nothing to do with yachts importing it.

RNZ understands the suspected caulerpa was found near boat moorings - but Omaha Cove also has a wharf used by commercial fishing boats, including those permitted to work in the controlled areas around Aotea Great Barrier where the pest is rife.

Commercial cray fishers have been allowed to continue operating, setting cray posts INSIDE the CAN at Gt Barrier. Hence why Auckland Council thought Leigh Harbour might be a 'high risk' location for an outbreak.

I understand the Barrier locals are highly traumatised that while they have been banned from collecting seafood, commercial fishers from the mainland continue to operate right in their faces.

But for some reason, while commercial interests set cages on the caulerpa infested seafloor, recreational boaties are banned from anchoring and blamed in the media for caulerpa's spread...

Welcome to reality, the business of making money comes first, (until the end of June)

For Great Barrier Island, three time-limited permits (to end of June 2024), that include
very strict conditions for operations, have been granted for the purposes of
commercial rock lobster potting within Great Barrier Island Zone (Zone A) only.

Thanks for the link Psyche:

Residents on Aotea/ Great Barrier are furious after commercial cray fishers were spotted in waters covered by a fishing ban under Caulerpa rules.

“That commercial operators are dropping cray pots in an area where this activity is otherwise banned is deeply offensive to locals, who’ve been carefully adhering to the ban for nearly three years now,” said co-chair Aotea Caulerpa Response Team Chris Ollivier

“It is also hugely worrying in terms of where those cray pots returned to after being at the Barrier, quite possibly with Caulerpa attached to them, and that is Leigh, the site of New Zealand’s poster child for marine reserves.”
