Wemyss Bight was a British-bred, French-trained Thoroughbred racehorse and broodmare. She was successful in her only start as a two-year-old in 1992 and developed into a top-class middle-distance performer in the following year. She won the Prix Penelope, Prix Cleopatre and Prix de Malleret in France before recording her biggest win in the Irish Oaks and also finished second in the Prix Vermeille. After being retired from racing she became a successful broodmare, producing the Arlington Million winner Beat Hollow. She died in April 2009 at the age of 19.
On her three-year-old debut Wemyss Bight was matched against the Prix des Chenes winner Dancienne in the Group 3 Prix Penelope over 2100 metres at Saint-Cloud Racecourse on 16 April. Starting at odds of 2.4/1 she won by four lengths from Dancienne with a gap of six lengths back to Miss Kadrou. Four weeks later, over the same course and distance, she followed up in the Group 3 Prix Cleopatra, taking the lead in the straight and holding off the challenge of Bright Moon to win by a nose.
Summer
Wemyss Bight was then sent to England to contest the 215th running of the Oaks Stakes over one and a half miles at Epsom Racecourse on 5 June. Ridden as in the Cleopatre by Pat Eddery she was made the 11/2 third choice in the betting behind Yawl and Intrepidity. She reached third place in the straight but looked outpaced on the good-to-firm ground in the last quarter mile and finished fifth of the fourteen runners behind Intrepidity, Royal Ballerina, Oakmead and Sueboog. Three weeks later, with Jarnet in the saddle, she started 6/5 favourite for the Group 2 Prix de Malleret over 2400 metres at Longchamp Racecourse and won by four lengths from Diamonaka. On 10 July at the Curragh Wemyss Bight faced Intrepidity again in the Irish Oaks and started 9/2 second favourite behind her stablemate. Royal Ballerina and Oakmead were again in the field while the best fancied of the other seven runners were Takarouna. Racing on her favoured soft ground Wemyss Bight was restrained by Eddery in mid-division before beginning to make progress in the straight. She took the lead entering the final furlong and won by half a length from Royal Ballerina with Oakmead four and a half lengths back in third, just ahead of Intrepidity. After the race Eddery explained "I was told to hold up Wemyss Bight for a late run. At Epsom she didn't pick up at all in the straight, but I was confident that her form overall was equal to that of the favourite. This time Intrepidity had an off day and my filly left her English Oaks form behind".
Autumn
The third racecourse meeting between Wemyss Bight and Intrepidity came in the Prix Vermeille over 2400 metres at Longchamp on 12 September. Intrepidity won the race but Wemyss Bight looked an unlucky loser after being denied a clear run in the straight and then finishing strongly and failing by only a head to overhaul her rival. Wemyss Bight was strongly fancied for the 1993 Prix de l'Arc de Triomphe on 3 October, going off the 4/1 third favourite, but failed to recover after being hampered halfway through the race and trailed in 21st of the 23 runners. Intrepidity finished fourth. On her final start she was sent to California to contest the Breeders' Cup Turf at Santa Anita Park on 6 November. She started a 41/1 outsider and finished eighth of the fourteen runners behind Kotashaan.
Breeding record
After her retirement from racing Wemyss Bight became a broodmare for Juddmonte Farms. She produced at least eleven foals and four winners between 1995 and 2008:
