if you are referring to: Within the City of Punta Gorda, living aboard boats and other watercraft shall be permitted only in marinas approved for such purpose by the Zoning and Land Development provisions of this code (see section 26-7).
I'm pretty sure that spending the night on your boat versus living aboard is very different. Especially when the Admiral assigns you bunk space onboard your ship that evening.
Trust us, if your neighbors turn you in, you will see PGPD and you will be guilty of a code violation.
