Qt switches automatically between gshhs tiles as you zoom-in and -out. There are 4 levels:
Level Filesize
f 166.8MB
h 32.8MB
i 10.6MB
l 5.0MB
SOL does this too, but does not have the highest level f tiles.
Also for ocean races, the SOL zoom-in only goes to level i.
There is an easy manual fix.
Proceed as follows.
Create three additional directories in the maps directory of your Qt application: call them say:
gshhs-orig,
gshhs-high, and
gshhs-inter.
Now go to Qt's own gshhs directory and Ctrl C:
poly-c-1.dat,
poly-h-1.dat, and
poly-i-1.dat.
Ctrl V them into your new gshhs-orig directory.
Now go to your new gshh-high directory, paste them in again, delete poly-c-1.dat, make a copy of poly-h-1.dat which will be renamed poly-h-1-copy.dat by your system and rename that copy poly-c-1.dat. You've now replaced the original poly-c-1.dat with a poly-h-1.dat file IN DISGUISE.
Next go to your new gshh-inter directory and place copies of the original poly-i-1.dat and poly-l-1.dat files in it. Make two copies of poly-i-1.dat and rename them poly-c-1.dat and poly-h-1.dat. You've now replaced the original poly-c-1.dat and poly-h-1.dat with a poly-i-1.dat file BOTH IN DISGUISE.
Once this is done, open Qt in the usual way and zoom-out.
Go to your Qt maps directory and if you are racing an ocean race, pick up the fake poly-c-1.dat and poly-h-1.dat files in the new gshhs-inter directory and Ctrl C them.
Go to Qt's original gshhs directory and Ctrl V them and select Replace.
Go to Qt and zoom-in. Your zoomed-in map stays at the i level, matching SOL.
If it is a coastal race, proceed in the same way, but picking up the dummy files in gshhs-high instead.
As long as Qt doesn't crash (as it will do every time you loose the NMEA connection) or you don't close it, you can now route away to your heart's content.
However, if you have to restart Qt and there are dummy gshhs tiles in its original gshhs directory it will not work. So... go to gshhs-orig and pick up the correct original files there and paste and replace them back into Qt's gshhs directory.

Version 5.3.12 has been released. It includes a way to force gshhs resolution to desired details level.

That's great stuff, maitai.
Does it deal wit Kipper's comments (below) as well?
If so, I think the time has come to upgrade once again (from 5.3-5 in my case).

1. Closing an NMEA TCP connection server port (closing the port or shutting down the programme providing the NMEA feed) while GPS is connected, causes Qt to crash.
2.If NMEA sentence $GPWPL is received for a waypoint that already exists, that waypoint jumps to the top left corner until a screen refresh is invoced. Each time the following sentance is received, the waypoint "Cadiz Offshore" will jump to the top left of the screen from it's proper location $GPWPL,3636.000,N,00629.000,W,Cadiz Offshore*0D
3. The Display Raw NMEA Data window, when activated, will obscure some of the other popup windows, and lock up Qt completely.To reproduce do the following.
i. Enable Display Raw NMEA data and start GPS
ii. Click on boat icon to bring up Position, Speed and Heading etc
iii. Click on Position, if not already displayed.
iv. Click on ? Qt will now be locked. The is now no way to move the NMEA Raw Data window and get to the popup behind it.

Yes it should fix all that too (and some more), plus it adds the possibility to specify a minimal distance from coast when routing

2016-08-26 14:11:52 - "Barriers"
Viva all.

Till the penultimate qT version (if I recall it right) it was possible to “associate” a boat with “barriers”.
That option went (for good).
The problem now, is that we can’t turn “on/off” anymore the barriers, which is not good.
In some races we need one particular “barrier” to be active, but just one, not all the collection.
For certain races, the previously built barriers collide with the routed paths.
It seems that the only solution left is to clean the old “barriers” as it’s not possible to turn it “off”, when needed.

This aspect needs to be solved.
Sail Fair.

Yes barriers are now always associated to real boat. You can ignore barriers while routing if needed, there is an option for that in routing parameters.

I take a note to add an option to hide thel, though.

Can someone confirm that the new options concerning gshhs resolution is OK for SOL races and correspond to your coastlines?

Good morning Philippe.

Using Autocad with the JPEG files from the qT and the SOL charts for the Vineyard race it gives a very good result.
I assume the very little differences result from the scaling ops I've made on both JPEG's before being "injected" in Autocad.

So, for me, it's good.

2016-09-01 16:40:38 - The WRF Grib file qT mystery
It’s really a mystery why qT can’t open to is full extent a WRF Grib file, Philippe!
If I load a WRF Grib file format to qT I only have 24 hrs of wind data.
In the SOL client we have 48 hrs.

Bug or fuss?
Pls, someone can explain this?

Thank you.
Sail Fair.

brainaid bug. the grib is capped at 1MB. brainaid had fixed that at some point, apparently that fix was reverted.

Red Eye - Myth of Malham 2025

In 1947, Hugh McLean & Sons of Gourock, Scotland built a radical racing yacht for John Illingworth, soon-to-be Commodore of the RORC, to a design by Laurent Giles. With a masthead rig, giving her ‘free’ sail area per the rules of the time, and short overhangs reducing pitching, Myth of Malham went on to win The Fastnet that year and again in 1949, and to compete in numerous Admiral's Cups. In 1958, in honour of the yacht, the Myth of Malham race was conceived - a mini-Fastnet to the first lighthouse on a rock west of Cowes, Eddystone, rather than the second, to be held in non-Fastnet years. IRL this year it has been raced already, but this stops us not from “Red Eye” racing its online 230nm in Fareast 31Rs, leaving how to deal with the Isle of Wight open to your own discretion.

Africa by Sea 2025 - Maputo to Mogadishu


The fifth leg of our exploration of Africa By Sea takes us north along the length of the Continent’s succulent sub-tropical and tropical Indian Ocean coast. Much fought over by traders and colonists both well-before and after a Portuguese expedition under the command of Vasco da Gama first sailed there from Europe back in the 16th century, it is yet to be properly explored as a yachting destination. With plenty of islands off- and inshore, small and very large, there is much to interrupt your 1900nm voyage and visit in your Swan 65, from Maputo to Mogadishu! Race #1858
