The Trebla was a 41 m long wooden-hulled cargo vessel, built in San Francisco in 1868 as the Santa Cruz and operated as a combination passenger/cargo vessel in the Bay area. The Trebla sailed from Vancouver for Victoria on her final voyage with a large scow in tow on 10 May 1924. Captain Berquist decided to shelter for the night in Saanichton Bay. Around 9 O’clock in the evening a fire broke out in the engine room and raced into the deckhouse. The vessel ultimately burned to the waterline and sank.
This is a model of one of the unique features at the Trebla wreck site: a Babcock & Wilcox water-tube boiler. What you are seeing is the round steam drum between two large headers. The headers connected water-filled tubes running through the firebox to the steam drum.
