What did the boatman say about Betsey Trotwood in David Copperfield?

In David Copperfield by Charles Dickens, Miss Betsey Trotwood is David Copperfield's eccentric, sharp-tongued great-aunt (on his father's side) who seriously disliked and distrusted men. Nevertheless, underneath it all, she had a kind heart, and she took David in, sent him to school in Canterbury, and helped guide his life until he got married and embarked on his literary career.
After Mr. Micawber was released from debtor's prison and decided to move with his wife to Plymouth, David ran away from his dreary, degrading job in London labelling wine bottles and set out to find Miss Trotwood, his only living relative, who he learned from Clara Peggotty was living in Dover.
After six days of non-stop traveling—and a few harrowing adventures along the way—David arrived in Dover "a dusty, sunburnt, half-clothed figure" in "ragged shoes."
David went to the harbor to make inquiries as to where he could find Miss Trotwood, which is where he met some boatmen.

I inquired about my aunt among the boatmen first and received various answers. One said she lived in the South Foreland Light, and had singed her whiskers by doing so; another, that she was made fast to the great buoy outside the harbour, and could only be visited at half-tide; a third, that she was locked up in Maidstone jail for child-stealing; a fourth, that she was seen to mount a broom in the last high wind, and make direct for Calais (chapter 13).

Evidently, some of these boatmen had either heard about or actually experienced Miss Trotwood's less-than-friendly attitude towards men, one of whom even characterized her as a witch who flew on her broomstick across the English Channel to Calais!
Later, David was directed to her home by a "fly-driver" (a driver of a "fly," which is a lightweight, one-horse carriage), where David was greeted with, "Go away! Go along! No boys here!"
After explaining who he was and his predicament, Miss Trotwood took him in, which was the beginning of yet another set of adventures in his adventure-filled life.
