Sadler 25
Encyclopedia
The Sadler 25 is a 7.42 meter (24 ft 4in) 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
. 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 and the (then) new fin
keel
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
keel
s, twin bilge keel
s 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 had many successes in longer events such as the Round Britain and Single-handed Trans-Atlantic races.
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.

Contessa 26
The Contessa 26 is a 7.77 meter fiberglass monohull sailboat, brought about when Jeremy Rogers, with a background in traditional wooden boatbuilding along with one of his Folkboat customers, David Sadler, created a modified version of the same boat in GRP...

Nordic Folkboat
The Nordic Folkboat is a small sailboat, rigged as a sloop. The design of this boat was the result of a competition held by the Scandinavian Yacht Racing Union in 1942, who were hoping to create an easily sailed and low cost boat...

Fin
A fin is a surface used for stability and/or to produce lift and thrust or to steer while traveling in water, air, or other fluid media, . The first use of the word was for the limbs of fish, but has been extended to include other animal limbs and man-made devices...
keel
Keel
In boats and ships, keel can refer to either of two parts: a structural element, or a hydrodynamic element. These parts overlap. As the laying down of the keel is the initial step in construction of a ship, in British and American shipbuilding traditions the construction is dated from this event...

Skeg
A skeg is a sternward extension of the keel of boats and ships which have a rudder mounted on the centre line. The term also applies to the lowest point on an outboard motor or the outdrive of an inboard/outboard...

Rudder
A rudder is a device used to steer a ship, boat, submarine, hovercraft, aircraft or other conveyance that moves through a medium . On an aircraft the rudder is used primarily to counter adverse yaw and p-factor and is not the primary control used to turn the airplane...

s, twin bilge keel
Bilge keel
A bilge keel is used to reduce the hull's tendency to roll. Bilge keels are employed in pairs . A ship may have more than one bilge keel per side, but this is rare. Bilge keels increase hydrodynamic resistance to rolling, making the ship roll less...
