How Can I View Drying Heights in CM93 ?

I am running the latest 2.1.0 build 624a on my Samsung N140 using 1024x600 res. My first day with this splendid piece of software.

I have the CM93 chart set and I have the settings:
4 colours CM93 detail+5
Shallow Depth 0m
Safe Depth 5m
Deep Alarm 10m

I sail on the East Coast UK, and need to sail over drying heights.
The charts display down to 0m, but no drying heights are shown, and anything less than 0m datum is just greyed out.
I have tried playing with the depth settings and this improved the display, but I need to see the drying heights.

Any help?

Many thanks for such a great forum.

I cannot help You for the flats and sands....., I suppose you need really specific local charts for this.

.....but if you change shallow depth to 2m , you will see one colour more ! dark blue for less than 2m.

in Uk and Netherlands the depth contours in cm93 are 2, 5 and 10 meter.

this depth contours in cm93 are changing depending on the country, in Sweden for example its 3, 6 and 10 meter!

so if you change country, it is advisable to check the depth contours and to change your settings.

Only in CMap cards...

Drying heights are not available in CMap 93 v2. These charts seem aimed at larger boats / ships (The Gulf of Morbihan (France) a famous playground for sailors) chart, available up to 2008, was deleted, possibly also the keep the size reasonable.
They are available on Cmap cards though, indicating this is a deliberate policy

Thanks Guys, I thought it wasn't just me being plank-like.

That really means I can't much use all the really good work, as my area is littered with sandbanks. Back to the C-Map planner on a Max card for the moment.
