I would send an e-mail to
cfd@gov.vg and ask them for the forms. Fill them out and e-mail back to them with a copy of your photo ID. They issued me a fishing license within 24 hours. They never asked me if the boat was a registered fishing boat, in fact for boat name I wrote "unknown" and filled in the charter company and the type of boat we are chartering. They never asked any questions.
If you want to send me your e-mail I can forward the forms to you.
Cost is $45, and it was very easy to do.
