I recalled from a thread that the OP owned, and foreign registered his boat. If that boat, that he owns, is still "in charter" then he does not need to get it as the charter company holds the certificate.

If it is not in charter, you need a CoI...unless you are lucky like sail2wind smile

from the OP's previous post, it is not clear..."We own, registered in Ohio but chartered in the BI" ...whether others charter his boat through a charter company
