For receiving and transmitting WiFi from you boat you need an amplified antenna. Your computer can receive the very powerful transmitted wifi signal from shore and show lots of "bars". But unless your computer can send out a signal that will reach all the way to the shore antenna you will not be able to use the wifi connection. It is a two-way transmission - so your power must be sufficient to get all the way back to the shore-side antenna. The few milliwatts put out by the computer cannot reach very far. So the "amplified Wifi antennas" have a powered signal booster in them to increase your transmitted signals many hundreds of times. Now "your half of the conversation" can reach the shore-side antenna and voila - wifi onboard in an anchorage or marina.
