    Currently being built in Australia and destined to be the first ever modern ocean racing boat to be assembled in the Middle-East, the first Arabian 100' trimaran will, when she hits the water in the winter of 2009, become part of a select group of the longest sailing trimarans ever built! She will join the Oman Sail Racing Team fleet as the largest sailing boat to be based in Middle-East region and, along with Musandam (ex-B&Q), form the embryo of a fleet of ocean racing boats based in the Arabian Peninsula.

    As announced recently, Musandam plans to depart for her first big ocean challenge in the new colours of Oman Sail on January 8th - aiming to get the first ever Omani around the world. The heart of Oman Sail is about getting Omanis out on the water, from beginners through the Oman Sail Academy to the highest level of ocean competition, and the new Arabian 100 trimaran will provide the team with unrivalled capacity to develop ocean racing in the Gulf and Indian Ocean.

    This new Oman Sail flagship has been been conceived as the first member of a new One Design class (identical boats), rather than a one off boat. On purpose, Oman Sail has not opted to simply build a bigger and better boat, with records like the Jules Verne in mind, instead the new Arabian 100 will provide a challenging and exciting platform very suitable to the often lighter wind conditions in the region as well as the storms of the Southern Ocean and within reach of the sailing capabilities of the developing Oman Sail team in the coming years. If, as it is hoped, the Arabian 100 becomes the Class of choice for other developing sailing teams in the region, thereby avoiding the arms race seen in other big unlimited multihull classes, the One Design aspect will create close combat racing, whilst remaining in a context of controlled costs

    Proud heir of the Musandam world-record breaking trimaran, the Arabian 100' is an already proven concept, developed by multihull experts Nigel Irens (UK) and BenoƮt Cabaret (FRA). Oman's new flagship is a direct development of Francis Joyon's IDEC, round-the-world record holder and sistership to Thomas Coville's Sodeb'O, currently attempting to break IDEC's reference time, and new holder of the solo 24-hour record, both also designed by the Irens/Cabaret partnership. The Arabian 100' will differ from her counterparts, in terms of deck and interior layouts, since unlike the French trimarans she has been adapted to be raced by a full crew of up to five.

    When working on the blueprint of this new speed machine, the designers took Dame Ellen MacArthur's B&Q (now Musandam) as a reference and adjusted the general balance given the increased proportions of just over 100 feet (32 metres). Relying on a long central hull that extends beyond the lateral floats, the Arabian 100' is safe at high speeds in rough sea conditions - her massive bow prevents dangerous nose-dives whilst sailing downwind, and thus allows for high average speeds over long periods of time.
    The sail plan, the "engine" of the boat, has been carefully designed to remain manageable even in stormy conditions, and the mast is stepped rather far aft in order to take some pressure off the forward sections (again to prevent nose-diving). To add clearance, the crossbeams are high above the water, ensuring the boat will not sustain any damage by repeatedly hitting the crests of waves - a phenomenon which has been known to become a speed-reducing factor for many ocean-going multihulls.

    Capable of speeds in excess of 35 knots (65 kph), this giant trimaran is clearly among the fastest ocean racers ever conceived, yet her programme will not include the classic European based records or solo races, being instead focused on the development of ocean racing in, and from, the Arabian peninsula region, and extending out along historical trading routes to Asia and Africa. At the head of the Indian Ocean and the gatekeeper of the entrance to the Gulf, Oman looks south to Antarctica, and east to India and Asia. These are the playgrounds for the ocean racing part of Oman Sail, and it is hoped in future, professional ocean racing in the Gulf region in general as other countries in the region take up the challenges that the new Arabian 100 Class offer.


    The first Arabian 100 should be sailing by the winter 2009, and the production has been implemented to allow the construction of further identical boats for 2010 if the challenge is taken up elsewhere.


    The Arabian 100' in figures
    Length: 105 ft - 32 metres
    Width: 54 ft - 16.50 metres across its 3 hulls
    Mast height: 115 ft - 35 metres
    Maximum sail area (approx): 5,920 square feet - 550 square metres.


    Building the Arabian 100' - process and timeline
    Major elements (central hull, floats and crossbeams) being built by Boatspeed, Australia using their highly successful "Custom Preg" system. The spars will be constructed in New Zealand by Southern Spars and the winch system will be supplied by Harken Italy.


    Assembly to take place in Sallalah in the south of Oman from May 2009. The assembly facility will be promoting apprenticeship and encouraging the sharing of technical knowledge, while at the same time showcasing Oman's forward thinking and opportunities.


    Launch date winter 2009
    2010 and beyond, series of record passages and event development in the Middle-East and Asia.

    These guys are not joking, this is the Biz.

    I worked in Sallalah, my brother up north in Muscat and our buddy Chris Beal and his wife Heidi in the Empty Quarter (the barren bit between Saudi and Oman where white lions roam).

    When Oman says its going to do something, it happens. No fuss, no bother. They do not just throw money at a project, everything is planned and worked through.

    Nigel is, I think, the best multi-hull designer going today (he also does very nice Classic boats too, an East German mate has one). Very sound ideas have been bought to the fore.

    Bringing the mast aft, after watching B&Q/Kingfish get a bit pitchy, is a smart move. An addition of more bouyancy in the bow sections should stopped some burying.

    There are many Bad-Boy cats and tris knocking around the boat yards going cheap, fine sailors in the Gulf(Sinbad the Sailor was a book from an old Omani Cruising guide of the 12th century). It should be an interesting series.

    Hi,

    It looks like on paper that the French have some serious challengers to the title of Madest Multihull Sailors then.

    Any clues as to how many Omani's will actually sail on these vessels or will it be like the Americas Cup where it is basically two similar nationality teams challenging each other under different flags?

    It sounds as thogh its more of a regional sailing effort to get sailing programs started in that area they are attempting to develop as a tourist and second-home site.
