The Only yacht constructed by the Foss Launch and Tug Company of Tacoma. Originally christened 'Thea Foss' after the company's founder. The Keel was laid in 1929, with the boat being used as a means to keep the Foss Shipyard workers employed during the Great Depression. She was completed and launched in 1933. Her Current name 'Mitlite' was given to the boat by Henry Foss and the boat's Second Owner John Metzger after the company purchased the considerably larger yacht 'Infanta', now 'Thea Foss'. 'Mitlite' refers to the boat being their "Little One" as in their little 'Thea Foss'
