Can you help me understand these phrases? "They are only across a narrow bit of water".

Informal: "[Hitting on some skanks."

A narrow bit of water is most likely a river or a stream.

Hitting on somes skanks just means that your flirting with women. You won't get very far if you call a woman a skank. It's a pejorative and similar to calling a woman a slut.
