How did you get on? there were a couple of tricky ones.
Here are my thoughts
1. 
Vessel over 50m aground
2. 
Vessel Not Under Command making way
3. 
Pilot vessel at anchor
4. 
Sailing vessel port aspect underway
5. 
Trawler over 50m Bow aspect making way
6. 
Vessel over 50m Stbd aspect Restricted in ability to manoeuvre making way
7. 
Vessel less than 50m pushing another vessel, port aspect, length of push less than 200m, under way.
