The Washington State Ferries (WSF) are about to launch their widescale test: One route had to be dropped because they couldn't secure a mid-run antenna location, and service would have been interrupted for six minutes. The first major route to have onboard Internet access via Wi-Fi is the popular Edmonds-Kingston route starting in a week; then Seattle-Bainbridge Island. These two routes comprise near half the system's traffic. The WSF operates about half the ferry trips in the United States overall.
While earlier, the ferry system had set an time limit on the free test part of this project before they bid out to a private contractor to operate, this article states the service will be free for three months.
