A maxi yacht usually refers to a racing sailboat of at least 70 feet (21 m) in length. It is also a Swedish brand of smaller sailing yachts.


The term maxi originated with the International Offshore Rule (IOR) rating system, which in the 1970s and 1980s measured offshore racing yachts and applied a single-number rating to each boat. This number was approximately equal to the sailing waterline length in feet, plus or minus speed enhancing or reducing factors in the design. A yacht with a rating of 40 feet (12 m) was generally about 47 to 52 feet (14 to 16 m) in length overall. The IOR had upper and lower rating limits of 16 feet (4.9 m) and 70 feet (21 m), so a yacht designed and built to the maximum limit of 70 feet (21 m) rating was known as a maxi.

Being the biggest sailing yachts afloat, Maxis have always had the best chance of finishing first. They were sufficiently fast and seaworthy to cross oceans and became the craft of choice of pioneers of the Whitbread Round the World Race, now the Volvo.

The racing giants in the Maxi Yacht Rolex Cup 2005 are the modern descendants of those early aquatic thoroughbreds. The rules governing the Maxi’s eligibility to race have since been relaxed and new technologies have been allowed to advance the speed and agility of these great behemoths.[1]


The IOR Maxis were generally 75 to 82 feet (23 to 25 m) long overall, and raced boat-for-boat without handicap, unlike the rest of the IOR fleet which raced with a time correction factor depending on the boat's rating.

For a time in the 1980s they were the most glamorous, exciting, expensive and high-visibility racing yachts in the world, with regular appearances at most of the great races such as the Fastnet, Sydney-Hobart, Bermuda Race, and their own private series of regattas in the Mediterranean, Caribbean and elsewhere. The maxis were also prominent as line-honours winners in every Whitbread Round the World Race (now the Volvo Ocean Race) from 1973 to 1993.

Match Racing & Fleet Racing[edit]

These boats are generally custom-designed and built. Thus, each one is unique. But some are built to conform to class specifications that make them capable of similar speeds. One recent example of a maxi yacht class is the "maxZ86" specification. Maxi yachts are raced in both short-distance buoy races and in offshore ocean racing.

Modern Maxis[edit]

A new breed of even larger racing yachts are now being built - at 90 to 100 feet (27 to 30 m) these are larger in every dimension, and much faster than the old-style maxis, and are commonly referred to as supermaxis, and these relaxed rules are spawning a whole new breed of record breaking super-sailors:

The first Super-Maxi owners, the New Zealanders Charles St. Clair Brown, a businessman and self-made millionaire, and his co-owner, Bill Buckley, an engineer, were encouraged to build their yacht, Maximus (later rechristened Investec LOYAL), they say, due to the relaxed rules.

I liked the idea of building a boat for Maxi regattas, says St. Clair Brown. I thought the world of yacht design (for example, the America's Cup[2]) had become too focused on designing around class rules and parameters, with the sole aim to beat the rules or over-performing within the rules.[1]

Obsession with quirky class rules diverts energy and effort from improving the performance and appeal of the sport itself into tuning around design limitations. This misdirection has been recognized by several maxi ex-campaigners; seemingly the entire sport.[3] are right behind this sentiment; so the Maxi Circuit is undergoing a resurgence.

New Rules[edit]

Like Maxis, the new generation of Super-Maxis (such as Ragamuffin Loyal, Esimit Europa 2, ICAP Leopard 3, Wild Oats XI, Lahana or Rambler 100) are built specifically to win line honors, but these days, have just a single constraint of keeping their length to 100 ft (30.48 m), in addition to the constraint of having only one hull. Mini-Maxis, such as Alfa Romeo III (69' in length), still compete for corrected-time titles, however.

The new rules permit experimental technology such as rotating wing masts – which are most commonly found on high-performance catamarans – light weight materials such as carbon fiber and epoxy resins, along with more established technologies like water ballast, canting keels, and asymmetric spinnakers. These relaxed restrictions in class design should prove to keep the innovation and the excitement on the water, rather than in the courtroom, which has been a major criticism of the America's Cup syndicates over the years.[4][5]

Other uses[edit]

Maxi is also the brand name for a range of production sailing yachts designed by Olympic medallist Pelle Pettersson and built on the Swedish Island of Gotland for more than 30 years. More than 16,000 Maxi cruiser/racers have been built to date with overall lengths up to 13 metres. Current production boats include the Maxi 1050, Maxi 1100, Maxi 1300 and the Swedish Match 40.
