Here is a diagram of the Washington State Ferry: Wenatchee.

The Wenatchee is what is known as a Jumbo Mark II-class vessel and was put into service by the Washington State Department of Transportation Washington Ferries division during the 1997/99 biennium. There were three virtually identical ferries put into service during that time and they were christened the Wenatchee, the Puyallup, and the Tacoma. The Wenatchee carries 202 vehicles and up to 2500 passengers.  It travels at a speed of 18 knots and has four engines that produce 13,200 horsepower.  All three of these ferries were built locally in Seattle.

Additionally, the ferry Chelan was put into service in the early 1980s.
