Does anyone know what this chart symbol means?

[baldhead]

looks exactly like a hash on a telephone keypad;
# but slightly wider..... Any ideas? /forums/images/graemlins/confused.gif

remains of a wreck, not dangerous to surface navigation but don't anchor!!

 

[baldhead]

i thought that was more a horizontal line with 3 vertical lines crossing through it, the middle one being slighlty longer

It's a 'foul ground', i.e. no problem for surface vessels, but likely to foul anchors or trawl nets.

Admiralty, Imray, Stanfords, or Foreign Charts?
I cannot recollect that symbol printed on any of my charts, which are mostly German charts, and some Admiralty, for Turkish waters. Unfortunately my book of chart symbols is on the boat, so I cannot look it up. On one of my charts someone has added an area of cross hatching, and marks a bit like that to show fish farms, but I am not sure if that is the proper symbol.

 

[baldhead]

ahh yep-that makes more sense... No chance of it meaning currents in a restricted area? that was the other option
Dont have a copy of the admiralty you see!

It is foul ground in NP5011. Appears as a question in this year's RYA Day Skipper assessment.

Could be the remains of a wreck, I would not anchor there.

 

[baldhead]

there are a few of them slap bang in the middle of 'foul ground' on the chart, so makes sense!!

 

[stephenh]

Here it is chapter and verse from 5011

'Remains of a wreck, or other foul area, no longer dangerous to surface navigation, but to be AVOIDED by vessels anchoring, trawling, etc'

 

[Norman_E]

The only chart I have at home is a practice chart, which marks foul ground differently, by enclosing the area within dashed lines, with the words "Foul Ground" or "Spoil Ground" inside.

 

[baldhead]

Great thanks for that

 

[tugboat]

Sorry, that was a typo. Now edited.

I think you may have stumbled upon a fantastic gap in the market.
If they can erect windfarms why not fast food eateries? Stick one in the middle of a shipping lane and youd be rushed off your feet /forums/images/graemlins/wink.gif

There is an online (american) version of Admiralty chart 5011. If you look at page 3 here http://chartmaker.ncd.noaa.gov/mcd/chart1/hydro/K.pdf you'll see the symbol and explanation

5011 is also International Chart 1. Any country publishing it will use the same symbols, although the language describing them may be different.
