Yes, overnight parking permits are available for purchase at the harbor office for $30/night.
Not certain every question but yes you can stay overnight just checking with the harbormaster before you leave. I have never gotten any tickets there and have stayed there many times overnight 2-3 days. Make sure you have a valid permit or ticket on your dash before you go out. Otherwise they will tow you
Yes you can even camp in upper harbor. For a fee
I'm ALMOST positive if you pay for them up front. You figure people are out on their boats 😉
