This is the bit I want to see verified with some real science/evidence

Its all in here, and that's not what they say, mostly.
This is the scientific advice given to councils to base their responses on.
Just reading the executive summary is enough to make you realise the councils ignored the report, mostly.
You are wasting your time and our money trying to stop it. There are guidelines as to what needs to be assessed before eradication efforts should be made for new introduced species.

Boats like that don't go anywhere
I'd be pretty sure it didn't catch the fanworm from somewhere else either.

Thats the problem they are attempting to control.
If that were true it would apply to commercial vessels and antifouling would have additives that worked.

Whats hard about the Auckland rules is that you must keep your boat clean at all times.
Up north you only need it clean if you move between "areas".
Councils were supposed to be working together to align their rules, so much for that.

This looks to be applying to sanding or grinding methods if you are local. Don't let your antifouling dust blow away in other words
No, its all about cleaning boats in water.
Wait till you start getting barnacle growth in Auckland like you get in the Bay, your whole hull can be covered every two weeks for about 6 - 8 weeks over summer. You think every boat in Auckland is going to get hauled every 2 weeks to stay compliant?

"Cleaning technologies should capture debris greater than 50 micrometres in diameter"
I always thought this must be a typo, 50 micrometres is barely visible (0.05mm).

YNZ and the Inspectors are meeting tonight to review the findings of the Essence report
So YNZ changed the rules before the investigation report came out, that makes sense.
They changed the rules before they consulted with the inspectors?
Lets hope some sensible official guidelines come out of this, its the inspectors are at the front line having to deal with the rules, be nice if they had some input.

Probably better than having a Govt. Dept,paid bureaucrat,and costs imposed by them ?
I think you actually have both, neither of which appear to be very competent.

The Yacht was on its way back to NZ, Cat 1 did not apply for that voyage. MNZ seem to be talking as if it did.
As DF says, maybe that design is deficient and should be banned?
Maybe everyone should have pre approved routing before being let go?
Maybe some Navel architect, yacht designer, Boat owners, Clubs had some input into the new rules? Love to see the correspondence.
many other unrealistic possibilities available, just like a few bits of screwed plywood would have saved this yacht.

The deck slowly bent upward under the head sail sheeting loads and all of a sudden a couple of windows just popped out of their holes.
YNZ reckon a couple of ply shutters and a few screws would have fixed that. Actually windows probably small enough to get away with none, still giving Cat 1 to this model are they?

I doubt if many inspectors have the engineering training to make such a call
So who's judging the engineering adequacy of these shutter things?
Comments above point quite rightly to the possibility of some efforts making a boat less sturdy, let alone completely ignoring the engineering of a particular boats construction.
26 minutes ago, BB7 said:so a blanket solution is the only way to do it....
Probably exactly what isn't appropriate in this case, too many variables.
Do you really think some bits of ply screwed to the outside of this boat would have saved it? Far bigger issues at play this time I suspect, however we will never know.
Boat didn't seem capable of handling conditions it was supposedly good for. I don't think it was a crew or experience problem.
How many disaster stories have we read where the liferaft was missing when they went to get it?
Lots of stuff gets swept off decks in a good storm, why take the risk? Been working on that problem for a while but on deck still seems to be a pretty risky spot, regs. still keep insisting thats where they want it. Don't recall too many stories where the crew couldn't get the liferaft out the hatch when they wanted it.

That would be Nuclear / Oil / Coal Electric Power, probably not popular around here.

I use a cassette on the transom with a drop in blade. The jockey pole is the tiller. You can borrow it if you would like.
Any chance of a picture at some stage? I'm thinking of a similar setup, would love to see one already done.

8.5m Waves off Bay of Islands

7.5 off Bream bay

Lots of issues covered in brief.
YNZ needs to take note, they seemed to be well down the track of following the old WS leadership policies.
From the new CEO, who seems to pretty on the ball:
" In my opinion far too much emphasis is put on the Olympics at the expense of other elements of our sport, and this unhealthy emphasis is not actually reaping rewards."

I've made and reshaped several rudders and always tried to get close to the basic NACA 0012 profile. Search online, you can get find calculators that will print out profiles etc.
For what you have it's a lot cheaper to stick with transom hung and there is nothing wrong with that.
If the pintles etc look strongenough. I would try add a couple of inches on the front of what you have and get a bit of foil shape in it. That will take some load off the tiller, improve performance and won't cost much.
You really need to sail it a bit after that to decide if you want to put big money into it for either a new transom hung or spade rudder.
-
Rudder balance comes from the line of the pintles relative to the blade centre of effort, the rake does not matter. Hard to get your head around but the water doesn't know its raked and that's what matters, don't do what your proposing no matter what you decide.
It could probably do with a bit of a lead on it to get some balance and a better foil shape.
What's actually wrong with how it works at the moment?

Tim - Ocean surveys -0274208212
Nathan - BOI Mobile Marine Services - 0226925703These guys surveyed my last yacht for the buyer in Opua. I thought they both did a pretty good job and would recommend them for Northland.
Buyer paid for everything but it's all negotiable.

What about the heavy weather jib? Has to be exactly 70%? Anything smaller or larger is incompliant. Should they add "at most"? Sounds like Shakespeare's pound of flesh!
Look up a few posts, my last one, the crystal clear answer from the rules.

Air NZ and Unilever are not lead and staffed by career bureaucrats.
Promotion from industry avoids that too. Real world experience, frowned upon by current government, has benefits in management but conflicts too much with the dream.

I'm actually interested in the CPR in community numbers.
The last course I did spent a bit of time on the defib thing. A couple of points I picked up.
You are something like 400 times more likely to need a defibrillator than a fire extinguisher, have a think about which one is mandatory in the workplace, or boat.
Seconds count when it comes to resuss. Getting a defibrillator on someone as fast as possible should be pretty near the top of the priority list.
Download the AED Locations app, there are a surprising number of them around.

New Hull cleaning regs for Auckland - more costs....

I'm really looking forward to the day that someone with enough money, time and good lawyers goes down this track.
You are being potentially fined / prosecuted for having an infested boat that was infested by the service that was rented to you by the same people that are fining you.
There is something fundamentally wrong with this scenario, I wonder if a complaint to the ombudsman might be a cheap way to get things rolling.

I have heard of someone dealing with a notice by telling the council "it was clean when I put it in your water" they never heard any more about it.
