Really late to the forum this week so hopefully won't cause any annoyance, but SPOILER ALERT anyway. I'm interested to see that no one else has a problem with 5A, so I guess I'm missing something really obvious. That said, I don't understand how the clue tells us to insert t in the middle of moors. Moors only makes sense as part of the solution if the part of the clue that generates it is 'STOPS boat moving'. Consequently 'stops' can't also be used to signify the insertion of t in anything. What the clue's syntax actually tells us to do (with the signifier 'around') is insert t in a synonym for 'moves quickly', with the definition being 'stops boat moving', but of course that does not generate an answer. Any pointers to why the setter's right and I'm wrong gratefully received.
