@machpants so recognised as both but i get a "nah"? not just "its both"?
the metric system is based on the metre...hows is something thats 1852m considered metric? im genuinely curious
Metric system is based on measurable things, not (for example) the length of some Greek blokes' foot, or 1000 paces. 1852m is metres and also standardised length of a minute of the earth, a mile is a mile because it is a mile. You can convert a mile to metric, but the official (now) definition of a NM (thus knots) is based on metres, not on the old Imperial system. Yet it started in the Imperial system, and is part of both. Quite unique, but it is offically part of both. The US Admiralty and UK Admiralty NM are both Imperial measurements, based on feet. The International Nautical Mile is metres/metric and set in Monaco under French rules La Metric systeme
'NM is Imperial?' (both) Yeah (and) Nah.
Well that's how I was taught in RN and RAF both of which use a mixture of metric and imperial, this is improtant stuff when you are bombing and navigating and shit. A bit like the time on GPS clocks being out for quite a few years.

well, kinda mostly. A metre is 1/10,000 of the way from the equator to the pole. Except that varies depending on which pole ... and changes over time. The kilogram for ages was based on a reference kilogram held in Paris... which is kinda arbitrary... like someone's foot
I think the metric strength is the base 10 ratios are the real strength, and the subseqent linking to definitions that are can be calculated and developed independently is a great evolution. But initially, it was kinda arbitrary

Almost all of the comments about the nautical mile are true. Which is amusing, in that we can manage to disagree / clarify on issues that have changed, and do change with time, including the semantics. The earth being an oblate spheroid that is constantly on the move is an annoyance that we have to live with.
Full disclosure: 100% in commercial pilot navigation exam (I think these things have come up about school C so thought that I should throw that in there) and a whole bunch of other shit that nobody wants to hear about.
I think that we should discuss map projections now. What is everyone's favourite and why? I've always been a fan (shouldn't use that word, the lambert conical supporters will be all over it) of the Mercator. It just makes NZ look bigger. A bit shit for navigation, but the symmetry is nice.
As for the racing- it really is getting boring. Port entry wins unless someone seriously screws up. I think that we do have an edge in speed overall, but if we are behind it isn't enough to get in front. @Crucial may well be correct and with one extra port entry that might be the decider.
The engineers, designers, etc, did a great job with fascinating machines to watch but the race organisers, committee dropped the ball IMO. Too much about spectators on shore, TB coverage and not enough about creating a contest between the boats. Wider courses with probably longer races would have helped. can anyone remind me when there was a pass? I feel that I can just watch the start and walk away now.

True and fair enough
Mercator is a classic obviously, from a usability point a view nz’s meridional circuits are top notch, but I would say that

@snowy so to summarise, the earth is flat?

If you use a big enough scale, yes!
I do like me some Myriahedral Projections
Not for actual navigation tho

It would make things easier. That sky fairy really fucked it up.

Milo.
I will be fluent in Polish before I am done with the Fern.7-11kts according to AC website for the match. Have they announced a course?

Some variety today, the other race track course to be used.

That start is stunning incompetence.

TNZ look to be covering more distance again.

I thought the Mercator had been confirmed to be racist?
You Racist.
In any case, with any of the cylindrical projections, including your racist Mercator.... I much prefer the version with China in the middle, rather than Europe. It just fits so much better, and incidentally with pleasing symmetry. -
