Sailing Ratios

Classic yacht-design ratios worked out from the builder's published figures, each shown against the bands designers read it by.

Most builders publish a light displacement. The ratios were defined on a loaded boat, so every boat here reads a little lighter than a surveyor's figure would — all alike, which keeps them comparable.

Tanks

What the builder publishes about how fast, how strong and how much the boat carries.

About Oyster Yachts

Premium production

British builder of luxury bluewater deck-saloon sailing yachts, founded in 1973 and led since 2018 by owner Richard Hadida.

Oyster's founder Richard Matthews launched his first cruiser-racer, the UFO 34, designed by Don Pye of Holman & Pye and built by Landamores in Wroxham, in 1973; the first Oyster-branded yacht, the Oyster 35 of 1978, pioneered the deck saloon that has marked every Oyster since, and the range grew through more than fifty models, including the Oyster 80. Early Oysters were racing cruisers whose seaworthiness turned them into bluewater cruisers, and a brokerage for pre-owned Oysters opened in 1984. Rob Humphreys was commissioned to design the Oyster 53 in 1999 and in 2012 drew the first of the sixth-generation G6 hulls -- sleeker, with a wider beam aft -- carried through seven models including the award-winning 565 and 595; Oyster Charter was set up in 2005, and the Oyster World Rally, launched for the fortieth anniversary in 2013 with 28 yachts, sailed again in 2017 and 2022. In 2018 Richard Hadida became the new owner, bringing investment, a new generation of yachts and record orders for the 565 and 595, a team of over 600, and the Oyster 495 built at the Hythe facility near Southampton.
