Had a situation the other day where my other half was heading for a collision into an island, she managed to stop in time and was at anchor , however she could move no further forward or left or right otherwise she would have hit the island.

I couldn't for the life of find what the rules had to offer in this situation,

Is there a feature for "reverse"?
Is the ship just stuck there unable to do anything else?

What we're the options here, maybe I'm just missing something.

Thanks in advance.
