Need help wth Bridge for hotspots

I need some help with a setup that I am trying to use on my boat. I have cable internet at the marina and I use a cable modem hooked to a Linksys WRT54G wireless hub and router. I use two notebooks with wireless cards. This setup works well.

I would like to have an external antenna high up on the boat to pull in hotspots when I am traveling. I have been told the way to do this is with a high powered bridge. I have installed a Senao/EnGenius 2611CB3Plus(Deluxe)

200mw bridge on the flybridge and plugged it into the Lynksys. I had to change the default address but after I did that I can communicate with the bridge. The problem is that there is no way to direct the bridge to a particular hotspot. Is there a high powered bridge that will work this way or am I going about this the wrong way?

I know a directional antenna would be helpful but I want to try and do this with an omni directional antenna with a yagi as a back up. 110 volts is not a problem. I would appreciate any help you can provide.

thanks
