Ditchburn Boats is the popular name for a manufacturer of wooden pleasure craft launches and racing boats located in Gravenhurst, Ontario on Lake Muskoka. At one time the company was the largest boat manufacturer in the lake region. Ditchburn operated from 1871 until approximately the 1930's building wooden row boats and canoes early in its history, and later gasoline powered launches. Ditchburn is particularly known for producing high quality mahogany launches which have become highly prized by collectors in recent years.

Early history
The Ditchburn Pleasure Boats Ltd was established in 1871 on Lake Muskoka by Henry Ditchburn to build wooden pleasure boats and launches. Joined by his brothers, William, John, and Arthur began by building wooden rowboats in Lake Rosseau, and moved to in Gravenhurst, Ontario in 1890. The company began building gasoline launches in 1898 along with roaboats.

Launches
In 1904 the enterprise was run by Henry's nephew, Herb Ditchburn, who partnered with Tom Greavette to reorganize the firm as the H. Ditchburn Boat Manufacturing Company. The firm built many custom built gasoline launches along with some stock models, mostly consisting of rear cockpit configuration with engine forward. In 1910 the company's line included 26 to 30 foot launches. In the late 1920's Ditchburn began selling forward cockpit designs. His was the largest operation on Lake Muskoka employing 30 men in 1921, expanding to 60 by 1923. Ditchburn met the ever increasing demand for gasoline powered launches by opening a second plant in Orillia, Ontario in the mid 1920's, increasing employment to 130 men. Ditchburn's reputation for quality craftsmanship grew opening its market to the United States, where eventually half the company's production was eventually shipped.

Ditchburn racing boats
Ditchburn was known for building a number of internationally-known racing boats named Rainbow, having been commissioned by Harry Greening in 1919. Greening ran the Rainbow series in the Gold Cup races. Rainbow III, developed as Greening's entry into the 1923 Gold Cup was a 25 foot boat powered by a Packard Six engine. While the boat failed to win the race due to a malfunctioning rudder, Greening later set a distance record with it on Lake Muskoka running 1,064 miles in 24 hours.

Some controversy surrounded Greening's Rainbow IV, built in 1924. The Gold Cup Race rules barred hydroplanes, but allowed lapstrake hulls. Rainbow IV was a lapstrake boat, but was planked crosswise rather than fore-aft, thereby giving her a number of steps on the bottom of her hull. While the design was challenged, it was eventually allowed and Greening ran the race, winning on points. However the victory was overturned when the American Power Boat Association upheld the challenge to the design.

In 1927 the company built a 28 foot racer for circus magnate John Ringling of the Ringling Bros. and Barnum & Bailey Circus fame.

In 1926 the company build six patrol boats for the Canadian government for use on the Atlantic coast based on the company's "Viking" model.
