VI Yacht Charters (www.viyachts.com) - if that's what you referring to - is simply a brokerage/booking agency contracting with many different yacht managers. They don't own or manage boats themselves (like BVI Yacht Charters does). They broker their clients to firms they contract with, such as BVI. I've personally never used them (VI or any charter yacht brokerage), but I might if I were new to chartering and needed a fair amount of hand holding in the process and wanted to easily "contact" many different boat charter operators without my direct involvement. Generally, fees for using a brokerage service are paid by the ultimate charter management firm (such as BVI) - well, really, ultimately by the independent boat owner for the boat you actually charter.
