Winnebago?
Good guess, Bushman.
I concur with Bushman's assessment. For that project in that climate, Davis is the way to go. (I hate to jack the AcuRite topic this way.) Perhaps you can do one or two stations at a time. After you get a couple on the web, then the other areas will clamor for their own.

For what you are trying to do on a lake that big, the cost of the weather stations is almost secondary. You will need 4 separate stations, and 4 separate internet connections. You COULD try to do some sort of add-on long-range wireless but it would cost more and be less reliable.
Then you will need either 4 24/7 computers and software, 4 WeatherLinkIPs, 4 WeatherElement data hubs, or other IP based connection between the weather station and the Internet. And then all the website back end, hosting, domain, etc.
For the ranch, we are installing 5 Davis VP2 Plus stations, 5 WeatherElement data hubs which send straight to our server.
Each station will have it's own WeatherElement page like
THIS, and after they are all on line, we'll make a station network page for them.
