SS Sir Walter Scott

SS Sir Walter Scott is a small steamship that has provided pleasure cruises and a ferry service on Loch Katrine in the scenic Trossachs of Scotland for more than a century, and is the only surviving screw steamer in regular passenger service in Scotland. She is named after the writer Walter Scott, who set his 1810 poem Lady of the Lake, and his novel Rob Roy of 1818 around Loch Katrine.

In 1859 Loch Katrine became Glasgow's main water supply, connected by aqueducts and tunnels to the city more than 30 miles (48 km) away through a hilly landscape. The Trossachs became very popular in the Victorian era, and there were early steamship services on the loch. The Loch is surrounded by wooded mountains, and has romantic historical connections including the birthplace of the outlaw Rob Roy MacGregor. Queen Victoria had a holiday house built overlooking the loch.

William Denny and Brothers built Sir Walter Scott as a "knock-down" ship; that is, she was assembled with bolts and nuts at Denny's shipyard at Dumbarton on the River Leven, the pieces numbered and dismantled again, transported in pieces by barge up Loch Lomond and overland by horse-drawn cart to Stronachlachar pier on Loch Katrine and there rebuilt with rivets and launched. Denny's assembled Sir Walter Scott at their yard in 1899 and completed her reassembly and launch on the loch in 1900.
