Two races would be better. I think they should combine C divisions. 1 w/l and 1 Island race each day. And do separate prizes. We don't do w/l at boi cause we never do w/l races, but if it was part of our series we'd have a good go at it and have some fun. This year some island divisions had boats that took 5hrs, so they probably would not be able to do this for every division.

After a bit more lockdown googling, I notice that the strake are very long, almost the full length of the thing being protected. https://www.cmrp.com/blog/bending/examples-of-vortex-shredding-mitigated-by-helical-strakes.html So this idea might not be practical. I remember racing on a tp52 out of Sydney that had this wire twisted around it all the way up the back stay, I always thought it was part of the ssb antenna until I discovered strakes.... Now that know what they are I can't stop spotting them... Eg...

I don't know. We stopped this humming on our running back stays purely by accident when we tied a bungy in middle to pull the lazy runner out of the way. The tight bungy stopped it dead by breaking the airflow. I noticed that the AC75s seemed to all have their strakes at different heights on their runners so you might have to experiment with it at different heights....

Von Karman Vortex Street - the same phenonem that causes a Chinese Gybe. https://en.m.wikipedia.org/wiki/Kármán_vortex_street You need to break up the air flow with a strake. Wrap some 0.5mm dyneema around it for about 1m at the bottom. Or put some balls on it, like a squash ball. You could also try shortening it by a few inches, reducing the harmonic length. ^^ Chimneys with strakes fitted to break up the vortices.

Have a friend who wants to install a new wind sensor. Wondering if anyone has any experience with the B&G WiFi ones that are charged by the wind and need no cables. Anyone had experience with these? Are they as good as the wired ones? Anything to watch out for? Thanks

No. In Auckland, just North East of the last location of interest

As the signal passes through the ionosphere each signal is delayed by a different variable amount depending on the properties of the ionosphere. To be able to provide pin point accuracy the receiving system needs to be able calculate the variable delay, this can only be done with 2 signals on 2 different frequencies. Having two signals allows the receiving system to determine the offset of each signal do some funky maths and get a highly accurate position. I don't pretend to understand the maths or physics behind this. I have not looked at any of the other GNSS constellations

It's like Wikipedia. So community policed.

Those are user updates, (community edits) they are not part of the LINZ dataset. You'll only see those on your plotter if it supports displaying community edits. On your phone you can disable community edits and you'll see the LINZ dataset.

It's the charts, not your GPS. There's a 'green fluffy' area defined as 'dries out at low tide' it's on the paper charts, so it's transferred to all the electronic charts. It's in most places around NZ, cartographers don't have enough accuracy at very close proximity. So safer to say it dries out.... We saw exactly the same at the hen and chicks South Cove. Tucked in close, 20m of depth, 10m from the physical shore, and the boat was in the green fluffy area on the chart plotter. Overlaying the Satellite image we were in the right place, ie the water not the land

I've used Cmap on Expedition on a laptop. Never used them on the Zeus. I found the Cmap charts just fine. The chart data for both products comes from LINZ. So it comes down to your preference on how each manufacturer presents it's data. B&G have some additional integrations for Cmap (due to fact they own them). Personally I use Navionics. It is what the plotter came with. It integrates with my Navionics phone software, upgrades seamlessly using my phone and I can sync routes and wayypoints easily with the boats WiFi. Relicensing the card is a PITA, but it doesn't stop working

The legal instrument is the Marine Mammals Protection Act, which allows a gazette notice to be published. The MMP restricts what limitations can be in a gazette notice. Any gazette notice is limited to what's in the MMP. So the gazette notice could enforce the full set of rules in the MMP (eg no access to a given area under any circumstances) or a subset of access under given conditions. Eg don't go faster than 5 knots...

It's considered unfair to series competitors to reschedule races where the NoR doesn't already allow for this. There is an ISAF protest ruling on this somewhere. Some boats may not be able to make the alternative date and as a result their overall standings in the series will be adversely impacted. To be able to reschedule races to a later date, an NOR needs to include the specifics, eg reserve days/dates that could be used. Then everyone would know about this as a possibility when entering.

I assume you mean mean the UHRD? If you do, it's not a law. You've said that international law trumps local law and in the next response said that there is no such thing as international law. Which is also wrong, there absolutely are International law's, they do exist and member countries have signed up to them. But the UHRD is NOT a law, it is not even a treaty. Your claim that the UHRD somehow guzzumps local law and that the BOI MMS rules infringe on your right to freedom to travel is fundamentally flawed. Your right to Freedom to Travel is in the NZ Bill of Rights Act

Yachting NZ did oppose this. Along with 100s of others. Either the supporters won, or the opposers were ignored....

This conversation/topic has come up here before during covid discussions, primarily when people discovered they were prohibited from departing NZ, dispite, 'freedom to leave', being a (so called) human right. The UDHR is not legally binding. It is not international law. It is a recommendation. In NZ, the UDHR is made law in the Bill of Rights Act. Your rights, listed in the bill of rights act, are limited by any law that can be justified in a free and democratic society. Given all of our laws go through three parliamentary readings and numerous amounts of scrutiny before being

Yes. Anywhere inside the EEZ is considered NZ. The law says that a boat shall not depart for a location outside NZ without approval. So long as you don't cross a black line you're fine.

I have been trying to find one for three years - do you have a NZ source. They pop up on ebay every now and again, but people have realized that they are rare as hens teeth and the price reflects such...

For next time, wool is considered rubbish and falls under the trash rules if it goes overboard. TRASH DISPOSAL 12.1 Boats shall not put rubbish in the water. Some clubs used to have a clause in the racing rules that allowed wool to go overboard when setting spinnakers, but I haven't seen this clause in several years - at least in any Auckland clubs. The answer now is velcro tabs, full length zips or old-school socks. Ofcourse if you ensure that all the wool falls on the deck and doesn't go overboard, all is good ISAF Q&A attached. QA2013.029N00

What about the bell? Are all the notifications acknowledged?

The Auckland regional pest management plan (RPMP) and the the marine pathway management plan has the rules specific to Auckland. The Biosecurity Act lets councils make up there own rules and makes it's an offence to break rules in those plans.

Yep - he anchors it there permanently on 100m of chain - at least he did - he used to move it before a big storm came to a rent-a-mooring or take it somewhere safe for a couple of days. It's just outside harbour limits so anchoring is allowed.
