I just put almost that on an owners new boat. 
http://www.tacktick.com/ 
It's all BT and solarpowered (except the depth sounder needs a  
  
 battery). 
  
It doesn't quite have the functionality you looking for, but may with  
the next firmware upgrade.

 Lionheart is wifi-powered, herself.  The serial port on a Noland  
 multiplexer goes to a Webfoot serial-to-ethernet interface: 
 http://www.i****chdogs.com/DataSheets/WF111803.pdf 
 It's fully DHCP addressable and gets its IP from a Netgear wireless  
 router's Ethernet port.  Up to 256 wifi devices can connect to it, like  
 The Cap'n running in the nav laptop through the "virtual serial port"  
 software that came with the Webfoot.  This handles the problem of serial  
 interface only on The Cap'n's archaic interface.  With the Wifi laptop,  
 you can get data off the boat even up in the parking lot of the marina,  
 half a mile away. 
  
 One day I happened to have the laptop in my haulings and stopped by the  
 marina office to discuss an electrical problem due to salt rot in the  
 pedestal box.  "Which slip is your boat in?", they asked me.  I couldn't  
 remember the number, so whipped out the laptop and brought it out of  
 hibernation as I knew the system on the boat was running when I left.   
 Booted the Cap'n and clicked FIND SHIP zoomed in tight and said, "Right  
 HERE on J-dock, as you can see by the live display from our network.", as  
 the marina people noticed the boat moving slightly on her GPS string and  
 the depth changing slightly because the tide happened to be ripping out. 
  
 I think we could sail it from the beach or dingy quite a ways away, sorta  
 "remote control".  With this in mind, I WEP protected the router so some  
 smartassed competitor in a race couldn't take control...not good...(c; 
  
 With the wifi link, it all integrates quite nicely to the old NMEA  
 network, just like it were on a wired serial cable.  It's totally  
 transparent to The Cap'n and the users, who do nothing but turn it on.   
 Great fun laying on a beanbag with the computer on your lap, beer in one  
 hand, clicking a new waypoint and calling back to the slaves in the  
 cockpit, "COMING ABOUT!" as the big wheel spins over by the B&G Pilot  
 tugging on her rudder post bellcrank. 
  
 Look on their faces when it worked the first time?......PRICELESS.

I think you may want to go a little farther than depending on WEP for  
protecting your network...  Netstumbler requires about 1 minute's worth  
of traffic to break a WEP key.
