You turn around when that little voice in your head starts saying "What the Hell am I Doing out here in this mess"

But seriously, you should turn around once you figure out what would be the chances ,that if I do go over or break something major, someone will be able to come out and get me.
Most other sailor would not give you too much grief about coming in. I would rather be safe on the beach getting joked than struggling to survive out on the water!
Sounded like a fun ride,
