The Jumbo class is a series of two ferries that were commissioned by the US shipping company Washington State Ferries from Todd Pacific Shipyards in Seattle and put into service from 1972 to 1973.

history

The two Jumbo Class ships were commissioned to complement the Super Class delivered five years earlier and built by Todd Pacific Shipyards in Seattle. Originally, the design of the ferries was to come from WC Nickum and Sons, as with the previous newbuildings of Washington State Ferries. Instead, however, the shipping company decided on a design by the ship's designer Phillip Spaulding. The Walla Walla was launched as a type ship in 1972 and was put into service that same year. Her sister ship Spokane followed in February 1973. Initially, the construction of two more units of the class was planned, but this was discarded for cost reasons.

Both Jumbo- class ships are still in service. The Walla Walla is used on the Seattle to Winslow route, while the Spokane is in service on the Edmonds to Kingston route .

Technology and equipment

The Walla Walla and its sister ship Spokane differ slightly in terms of their furnishings, as the public areas on the Walla Walla were renewed in 2005 and thus give a more modern impression. Otherwise, both ships have the usual seating and common rooms as well as bars and lounges for Washington State Ferries.

The two ferries are each powered by four electric motors with 8,617 hp, which can bring them to a top speed of up to 18 knots. Both the Walla Walla and the Spokane are considered to be very restless ships at higher speeds and are compared to the Kalakala , which was known for its poor sea characteristics.
