They have a capacity of 2,000 passengers and 188 vehicles.

Ferries in this class: * {{Ship|MV|Spokane}} * {{Ship|MV|Walla Walla}}

== History == By the late 1960s, Washington State Ferries was in need of new vessels to replace its aging fleet that required expensive upkeep. The extremely busy [[Seattle–Bainbridge Island ferry]] route was also outgrowing the {{sclass2|Super| ferry|0}} ferries that had been delivered just five years earlier.<ref name="evergreenfleet history">{{Cite web |year=2011 |title=The Jumbo Class |url=http://www.evergreenfleet.com/jumbo.html |website=evergreenfleet.com |accessdate=23 September 2012}}</ref>

The solution was an even larger class of vessels. Instead of just expanding the Super class, the state picked a new design from Phillip Spaulding, that would have a long, low look. This new Jumbo-class vessel would be {{Convert|440|ft|m|abbr=on}} long, {{Convert|87|ft|m|abbr=on}} wide and could accommodate 206 vehicles, at the time, the largest double-ended ferries in the world.<ref name="evergreenfleet history" />

[[Todd Shipyards]] in [[Seattle]] was awarded the contract to construct two vessels, with plans to order two more if the ferries worked out. While the agency was pleased with the vessels, the funding for the second set of two ships never materialized.<ref name="evergreenfleet history" />

The Jumbo-class vessels would be assigned to the Seattle–Bainbridge route for more than two decades, before they were displaced by the even larger {{sclass2|Jumbo Mark-II|ferry|0}} ferries. Since then, the Jumbo-class vessels have been primarily assigned to the [[Edmonds–Kingston ferry|Edmonds–Kingston]] and [[Seattle–Bremerton ferry|Seattle–Bremerton]] routes.<ref name="evergreenfleet history" />
