Before leaving Australia we saw references to cruisers using WiFi boosters in the Caribbean. We did some research and decided to buy a booster in Australia. Now we're here we are finding it very, very useful.
The reason these units are so useful is that there are so many countries here. Getting mobile phone SIM cards takes time and is expensive. And roaming charges are high. In contrast there are a number of WiFi Access Point ("hotspot") providers which cover many of the countries. With a booster one can easily connect to them from the boat via the booster.

These units (MikroTik and others) have all the WiFi circuitry in a "bullet", with a high gain antenna attached directly above (see below). The connection to the bullet is via ethernet cable. The units come with a PoE (Power over Ethernet) wiring harness with which 12Vdc is fed to the bullet. An ethernet to USB adaptor completes the assembly.

The only trick we found is that a DNS Server needs to be configured in Mac OS X's Network Preferences for the ethernet connection. We used Google's server at IP address 126.96.36.199.
