Here are the answers.
1. This line is a contour line and is showing the depth long this line as 10 metres.
2. The circled numbers are a spot depth, in this case 8.8 metres.
3. Its a navigation PORT buoy as represented by its "can" shape, the R means it is red in colour (therefore confirming a port buoy). The red magenta flash means it is a lit buoy and the QR means it flashes a Red light Quickly.
4. The fluffy ragged cloud shape represents a rock which covers and uncovers at tide, so caution when getting near to it. If it had a number on it such as 2.2 this would be its height above CD (chart datum - astronomical low tide)
5. A star shaped symbol with a white spot and a magenta flash beside it. 2F.R(vert) - The magenta flash means its a light of some sort, in this case it represents the end of a jetty as it has two fixed red lights (2F.r) mounted vertically (vert). Have a look at the gates/jetty at Heybridge basin next time you night paddle).
6. Who's been paddling here? Well Me and by the look of all the replies I've had, I was on my own.

UKHO Chart 5011 will give you all the abbreviations and symbols you want/need. Again look it up.

Hope you've found this useful.
