The Sadler 25 is a 7.42-meter (24 ft 4 in) fiberglass sailing yacht, designed in 1974 by David Sadler of Great Britain as an evolution of his earlier Contessa 26 which was in turn an evolution of the Nordic Folkboat.^[1] Although both the Folkboat and the Contessa 25 had relatively narrow long keel hulls, Sadler's new design utilised a wider hull to give more form stability^[2] and the (then) new finkeel together with a skeg-mounted rudder.

Built between 1974 and 1981, the Sadler 25 was normally rigged as a masthead sloop, and was offered with the option of deep or shallow fin keels, twin bilge keels or a centre plate.

In its deep-fin configuration, the Sadler 25 was a successful cruiser-racer which quickly became popular in yacht clubs throughout the U.K., and completed Round Britain and Trans-Atlantic voyages.^[2]

The Sadler 25 is widely regarded as one of the classic late-20th-century production yachts, and many examples are still giving faithful service both cruising and racing.
