With the promise of passenger only service realized with the Express (later
Tyee) WSF ordered a pair of new boats to expand the service.  The two,
Skagit and Kalama were built for  five million dollars  in 1989 by Halter
Marine of New Orleans.  The original design of these boats  were based on
one used to ferry   offshore crew   to oil rigs in the  Gulf of Mexico. WSF
altered the  superstructure by adding another deck to accommodate more
  Arriving in the fall of 1989 the boats along with the
Tyee were tied up.  
There were no funds to run them.  The state's newest members of the fleet sat
unused and in limbo.
  The Loma Prieta Earthquake in San Francisco put the boats to work.  
Loaned to the city while the bridges were down, the ferries proved their
worth--and it would turn out to be their finest moment.
  Returning to Puget Sound, the ferries went into service...and soon after the
complaints began.
  Designed for the Gulf of Mexico, the boats rolled with the waves.  The cabins
proved to be uncomfortable, freezing in the winter and sweltering in the
summer.  The residents along Rich Passage began complaining about erosion
on their beaches due to the the large wake the ferries produced.  To appease
property owners, WSF slowed the boats.
  They were successful on the direct route from Vashon to down town Seattle,
where the open water presented no issues with the wake.
  The pair proved to be unreliable and subject to frequent breakdowns.  
When Washington State Ferries started a new passenger only program with
Chinook and Snohomish, plans called for the Skagit and Kalama to be
retired.  Instead,  the  ax fell on the passenger only program in 2005.  The
Chinook and Snohomish were pulled off the Bremerton run and the full scale
dismantling of the passenger only fleet started,  beginning with the auction of
Tyee on eBay.
Skagit and Kalama were assigned to carry on at Vashon.    The
commuters on Vashon Island remained grateful for their ungainly boats.  The
two provide the link from the Island directly to downtown Seattle, instead of
going to the dock at Fauntleroy in West Seattle as the auto boats do.
  In the winter of 2006, the legislature directed the sale of the  
Chinook and  
Snohomish. The remaining passenger only run between Vashon Island and
down town Seattle was to be discontinued by Washington State Ferries by
After the summer schedule of 2009  King County took over the
Vashon-Seattle run, using the 149 passenger catamaran
Melissa Ann. King
County has plans to lease up to  three 149-passenger vessels: one for
Vashon; one for the water taxi; and one for backup. Eventually the county will
buy its own fleet.  
Skagit and Kalama were declared surplus in the fall of 2009.  The state
tried to sell them on eBay but were unsuccessful.  
The pair were finally sold in
2011 and  transported to Tanzania where they would provide service between
the mainland and Zanzibar.
On 18 July, 2012, after encountering heavy winds, the Skagit capsized off the
coast of Zanzibar.  A resulting inquest by Tanzanian authorities found the ferry
had been dangerously overloaded, carrying an estimated
447 people--well
over its capacity.  The final death toll from the disaster is a staggering 293
dead--although officially 81 are listed as dead and 212 as "missing."
