The International 5.5 Metre class was created to yield a racing keel boat giving a sailing experience similar to that of the International 6 Metre Class, but at a lower cost.
The main class regulation is a restriction on a single quantity output from a formula involving the boat's rating length L, weight (expressed as a displacement D) and sail area S; the regulation states that the output of this formula must not exceed 5.500 metres. There is considerable scope for variations in design while still meeting this restriction, and as a result each 5.5 metre boat is unique.
If the design parameters of a proposed new boat result in a formula output exceeding 5.5 metres, then one or more of the parameters must be suitably adjusted. Performance data gained from testing models towed in a long water tank (referred to in yacht design as Ship model basin) can suggest optimal combinations of parameters. The 5.5. metre rule is a variant of the
Since 2010 the 5.5 Metre is one of the Vintage Yachting Classes at the Vintage Yachting Games.
History
The 5.5-metre class was a redesign of the 6-metre class by
The formula
The measurement formula is given in the 2006 International Five Point Five Metre Rating Rules:
where
- = length for rating
- = measured sail area
- = displacement in cubic metres

Class association
The object of the International 5.5 Metre Class Association is to promote and develop 5.5 Metre racing throughout the World. The first President of the association was Mr. Owen Aisher.[9]
Since the development of the class spanned more than half a century the early boats are not competitive to race against the modern designs. Therefore, the association made, in 2007, divisions in the class based upon age of the boat:[10]
- Classic Fleet (Designs before 1970)
- Evolution Fleet
- Modern Fleet (Designs from 1994)
During major races there are separate trophies per fleet, however if a classic fleet boat beats the modern fleet, the classic fleet boat wins the modern fleet trophy.
