Early Milestones in Thames A-Rater History:

• 1870: Thames Sailing Club founded at Surbiton – Britain’s oldest river sailing club, destined to be “home of the Thames A-Rater”sail-world.com.
• Lubbock's Bank Holiday Act, 1870, and the release of Saturday afternoons from work, allowed aquatic leisure activities to spread to the lower middle classes during and after the 1870s; and ‘by the turn of the century even the poor came to assume that they had a right to leisure
  
• 1884: Upper Thames Sailing Club founded at Maidenhead (later based at Bourne End)yachtinghistorians.org.
• 1886: Adoption of the Rating Rule in December
• 1887: First Bourne End Week regatta held (for Queen’s Jubilee); the SBA is founded and adopts Dixon Kemp’s rating rulepublications.aston.ac.uk thedailysail.com.
• 1888: Formation of the Sailing Boat Association to run sailing on the river. The SBA was wound up in 1946.
• 1893: Queen Victoria presents the Queen’s Challenge Cup to UTSC, the only Royal trophy ever given to an inland sailing clubraterassociation.co.uk.

On 23rd June 1893, racing took place in strong and gusty north-westerly winds. Conditions were challenging from the outset—Ruby ran aground but managed to get free and continue. All boats began the race with reefs in their sails, though some crews shook them out during a brief lull in the wind. The rough weather took its toll: Folly became half-filled with water and was eventually forced to retire. Despite the conditions, the race was won by T. F. Knowles sailing Mona, a boat with a 0.85 rating representing Thames Valley Sailing Club. Second place went to Walter Stewart's Challenge, a 1.1-rated entry from Oxford University Sailing Club.

• 1900: Thames A-Rater class formally defined (0.75–1.0 rating, 3 crew) by the SBAraterassociation.co.uk. Also the Thames Champion Cup becomes a match race trophy (later the series prize at Bourne End)raterassociation.co.uk.
• 1903–1904: Trophies established for A-Raters on other parts of the Thames – the China Bowl at TSC (1903) and Braganza Bowl at Tamesis Club (1904)raterassociation.co.uk.
• 1900s–1910s: A-Raters flourish; designers experiment with larger sail plans, overhanging bows and sterns, and new rigs (lug to gunter to gaff). Club racing and challenge matches attract press coverage and public crowdsthames-sailingclub-history.thecomputerguy-it.co.uk.
• 1920s: Switch to tall Bermudan (Bermudian) rigs begins; masts built in wood-and-aluminium composite climb toward 40
• ftthedailysail.com. A-Raters face competition from emerging dinghy classes (e.g. International 14) and some fleets waneraterassociation.co.uk.
• 1930s: Innovations peak – trapeze gear (“bell ropes”) and twin sliding seats tested on A-Rater Vagabond (several years before such ideas in other dinghies)thedailysail.com. Legendary sailors like Beecher Moore and Peter Scott adapt these developments to mainstream dinghy sailingthamessailingclub.co.uk thamessailingclub.co.uk.
• 1950s: Decline – regular A-Rater racing ceases at UTSC and other clubs; only one or two boats (e.g. Scamp) keep the class alive at Bourne End Weekraterassociation.co.uk.
• 1980s: Revival – fearing the class “might die”, sailors build new fiberglass (GRP) A-Raters using moulds taken from an old hull (Ulva)raterassociation.co.uk. The influx of light, durable GRP boats rejuvenates the fleet (though initially dominating over the aging wood boats)thedailysail.com.
• 1990s–2000s: Restoration Renaissance – inspired by nostalgia and the GRP challenge, syndicates invest in restoring original wooden raters to full racing formthedailysail.com. Carbon-fiber spars and Mylar sails are adopted, blending classic craftsmanship with modern techsail-world.com sail-world.com. New trophies like the Yeats Cup (Tamesis Club) and events like the Three Rivers Race invite A-Raters beyond the Thames valley, even to the Norfolk Broads and overseas.
• Present: Around 20–23 A-Raters still race, many well over a century old. The class thrives as a unique cultural treasure – “the fastest dinghy racing on the river” – with an active association and dedicated crews continuing its legacyraterassociation.co.uk raterassociation.co.uk.
• At UTSC work is going on to restore Dainty Too and Estelle
• Surf has been scanned and taken to bits and is ready to be recreated
