guard at sea greater than or equal to 1.70 m (for vessels launched after the first of January 2015),
air draught not exceeding 120% of the largest length of hull found on the vessel;
rules that can be modified every four years (monitoring committee, group of experts, engine power, anchorages, adjustment of hull mobile appendages, skipper qualification method, etc.);
rules that can be modified every year, i.e. all those that are not part of the rules that are irremovable or modifiable every four years.
On the occasion of the Route du Rhum 2010, the organization of the race decided to group together in a new category all the multihulls of 60 feet and more, with no maximum limit of size. The aim was to succeed the ORMA class of the 60-foot trimarans, to wait for the construction of the MOD 70 for the year 2011 and to open the race for large multihulls such as Groupama 3 or IDEC 2.
Creation of the Ultime Class
In June 2015, an Ultim Collective formed around the Team Banque Populaire, Macif and Sodebo teams. They decided that the overall length should be between 23 meters (minimum) and 32 meters (maximum), which excludes the MOD 70 and Spindrift 2. The Mod 70 class boats, at 21.2-meters LOA, falls short of the class minimum. Spindrift 2, originally Banque Populaire V, at 40 meters LOA, exceeds the maximum permissible LOA for the class.
The Class Ultim 32/23 (maximum length 32 meters / maximum width 23 meters) was approved by the French Sailing Federation on 29 January 2018.[2]
Originally not considered to be part of the class, among other things due to a fully closed cockpit. After legal action of the team to be included in the class, the boat went through extensive rebuilding to allow the skipper more visibility during manoeuvring on the other hand fully closed cockpits have been allowed since.[4][5]
The Gitana Team has announced a new boat to be launched in 2025. The design team consists of Guillaume Verdier and Benjamin Muyl of the Orient Express Racing Team as well as the Gitana in house design team. CDK Technologies will be main contractor for the build, while Multiplast will be involved as well.[6]
The class has been part of the Rolex Fastnet Race since 2019.
Arkéa Ultim Challenge - Brest
In January 2023, the start of the first solo tour of the Ultimes, the Arkéa Ultim Challenge - Brest, was announced for 7 January 2024, with six participants. The maxi-trimarans will perform the round the world from west to east by the three capes (Good Hope, Leeuwin and Horn), about a distance of 21,760 miles from Brest to Brest. The organization of this race was entrusted to OC Sport Pen Duick.[7]
In its Jules-Verne Trophy record in 2009-2010, the Trimaran Groupama 3 in the hands of Franck Cammas travelled 798 nautical miles in 24 hours on February 13, 2010 featuring 17 days at more than 600 miles, including 10 days at more than 700 miles.
In its Jules-Verne trophy record in 2016-2017, the Idec Sports trimaran in the hands of Francis Joyon travelled 894 nautical miles in 24 hours,[15] with 10 consecutive days at 809 miles/24 h. Francis Joyon doubled Cape Horn, 16 days after hooking the first depression off South America, and after a trajectory of nearly 12,000 miles above an average of 30 knots (730.16 hours a day over 16 days). He then showed an increase in performance between 30 and 40% compared to the peak of Louck Peyron's record five years earlier. Leaving the Southern Seas with a 4-day 6-hour 35-minute lead on the previous record of Louck Peyron, Francis Joyon and his crew regained the equivalent of 2,800 miles at the record for this episode.
During the return after his victory at the Transat Jacques-Vabre 2021, Charles Caudrelier broke two unofficial records on the Maxi Edmond de Rothschild: in training in false-solo, he made a point at 50.7 knots, and traveled 880 miles in 24 hours at the average speed of 36.6 knots. The latter record may not be certified for lack of adequate equipment on board.[16]
