Here are the rules straight from the BVI. I guess the question is how you define proceed directly to a port of entry. I know almost everywhere else in the world it means nearest customs facility.

Immigration: Sundays and Public Hols.
Mon – Saturday 4.30pm to 8.30am.
Customs Mon to Friday after 3.30pm,
Sat & Sunday after 12.30 pm.
(inc’l Sundays and Public Holidays)
Mon-Friday: 4:30 p.m.–8:30 a.m. Saturday: 12:30p.m.–8:30 a.m.
Vessels entering the BVI should
proceed directly to a port of entry. Because jetty space is limited, vessels are allowed to anchor in the harbour before making their Customs entry. You may not proceed to a marina until you have cleared your yacht unless you are using a Ship’s Agent.No one may go ashore if you arrive after hours. You must raise your yellow flag. Permission may be sought in advance from Customs and Immigration for a late arrival by calling one of the ports of entry. Marina operators should ensure that vessels tied up at their marinas have been duly entered at Customs and Immigration. Only the Captain is required to effect the clearance procedures. The following documents are required:
Clearance document from previous port
Ship’s papers
Valid Passports for all crew and passengers.
The US Government requires that all US citizens traveling to the Caribbean must have valid passports to enable them to re-enter the USA. Some nationals require BVI visas. Refer to VISAS.
