Just returned last night from a charter with Catamaran Company. Five guys. They had a router on the boat with an option for 5 users @ $125 for the week. Definitely worth it, as we burned through our AT&T data really quickly trying a few FaceTime calls back home. Bandwidth on the boat router was good enough for FaceTime, forecast updates, etc. Of course, come with patience as you're accessing the internet from a boat in the middle of the BVI waters. Still pretty amazing to me.
