Re: Schooner Nina - MERGED 3 THREADS

Here's a couple of Ocean Current Direction piccys, Of the Tasman sea,

Hope it helps,

The reason I said they might be to the East of NZ, under Bare poles, they will drift that way, Out into the Pacific, Thats the way the current runs,

Above that easterly current, The South Pacific Gyre, above NZ, they will hit a west bound current and will end up on the great Barrier Reef,

Thats at the bottom of the Coral sea,

Re: Schooner Nina - MERGED 3 THREADS

These are schematics. Surface currents on top of NZ are pretty intricate with many smaller gyres. Consult NZ administration if you want actual data.

I'm putting on CF for people who know or may help with possible whereabouts of Nina. I checked a google map and found very interesting. Not smart enough to figure out though!

Re: Schooner Nina - MERGED 3 THREADS

You can see the latest current data in the following link...The currents in the middle of the Tasman are variable in the winter. Close to Aus, the currents are strong. Just pick a date:

uv

Some further info here:

Geostrophic current - Wikipedia, the free encyclopedia

Re: Schooner Nina - MERGED 3 THREADS

Isn't that what Equsearch are now being paid to do? Figure out the best places to search based on the information available and any modeling they may be capable of doing. I would be interested to see the area that they have already searched (and still intend to search assuming funds are available) superimposed on the excellent updated Google map at the link posted by Tboodro.

Re: Schooner Nina - MERGED 3 THREADS

I used the Current info on my boats GPS to work out the currents for that Cat that got abandoned in the Coral sea,

I was only 200 miles out from where it came ashore on the Great Barrier Reef, A month or so later,

The Nina's last position, Then follow the ocean currents from that point, 2 or 3 knots, then by the days since last reported,

Should give an approximate current position of the Nina.
Dont use the wind in your calculations,

The wind is anti clockwise here, and you get all four directions in the same day,

at boat speed of 2 knots, The wind speed would be irrelevant, as the boat is low in the water, EG; Bare poles, Nothing to catch the wind,

Deep Keel, so the currents have some thing solid to push against,

Wherever that current went, The Nina will be on it, Being shoved by the current,

Keep in mind that the search areas on that map may not be exactly to scale. But they should be a good representation. I'd be happy to update it as needed if anyone posts the update here.

Mr B brings up a good point about the currents. Looks like if they got far enough north the current may sweep them back west towards the Coral Sea.

If they did drift north, you would think that they't hit land, or at least be spotted at some point. Those island chains to the north/north east almost form a net. Lots of places to wash up. Heavier boat and air traffic that could spot them....
