On my way to Sugarbush, I took the ferry across Lake Champlain from Cumberland Head to Grand Isle. This is the northernmost and shortest of 3 crossings operated by the Lake Champlain Transportation Company. If you read the description you'll learn more than you'd ever care to know about this ferry crossing.
This recording is of the 7:05am eastbound departure, aboard the Raymond C Pecor Jr. Built in 2010, it's the newest in the LCTC fleet. It's also the biggest at 216 feet long, tied with sister ship the Cumberland, built in 2000. The Cumberland was the other ferry operating on the route at the time of this recording. There are 5 ferries assigned to this crossing, but they only run a maximum of 3 at once. The Vermont (1992), and Plattsburgh (1984) were docked on the Vermont side at the time of this recording. The Evans Wadhams Wolcott (1988) was likely at the maintenance yard in Burlington during this recording. The Plattsburgh is rarely used because it's shorter than the others so it can't handle the truck traffic this crossing gets.
This crossing is in operation 24/7/365. The fact that it's the most direct route between Plattsburgh and Burlington means it gets the traffic to justify keeping it open all the time. While Lake Champlain does freeze in the winter, the ferries constantly run back and forth in the same channel keeping things clear. All 5 ferries assigned to this crossing are capable of breaking ice too.
