Looks like "Paid" charter boat might not qualify for Buck Is anchor permit or overnight permit.
Probable best to call the NPS directly.

6. Commercial vessels are not eligible to apply for an anchoring permit. Applicants
will have to apply for a special use permit and will only be issued for private
recreation use only. Commercial vessels that are operating under a paid charter of
any type will not qualify for a special use permit. Please be advised that
providing false information or conducting unauthorized commercial activity
is a violation.
