Which is kinda laughable when they talk of high res modelling of the Hauraki Gulf. A quick google looks like they use their own in-house 'model' which sounds a bit like a mix of BoM's AXS & OCF models. There are also numerous references to EC and UKMet for high res analysis.
It's a huge wank. $$$ for the formula one of sailing. Those guys spent their lives on that water. Far better than any computer model.
