The designs were often determined by the materials available and nowadays space age construction techniques are possibly one reason that the modern boat is now becoming increasingly popular, as it is producing immensely stiff and strong yet light boats, capable of withstanding hard racing for several years. Upcoming Events. This is often the best place to start, as it’s not actually a hard boat to sail initially. Do not oversheet while doing the wildthing. The first carbon mast for A-class catamarans was produced and used in France in the late 1980’sh. As a result of this, Glenn Ashby won yet another world title. Helia 44 (2012) Photo: Insta @sailing_ella. The Maverick 440 is designed for a couple or family who wish to sail around the world in comfort, whilst having the ability to do all the things they love and enjoy the places they visit. To symbolize the two hulls the letter "A" had a double underlign, same  as the B's,  the C's and the D's. But in the early 1980s the ‘A’ class moved more towards an untapered wing type mast which was able to be rotated, somewhat like the leading edge slat on an aircraft wing, and thus create the sail shape more efficiently and to adjust it to cope with the windspeed changes created by the apparent wind. There are several elements key to the ‘A’ cats speed and success. But you can’t keep that friendly little Aussie down for long. Last edited by tomthouse; 06/26/12 10:39 AM. In ideal conditions you may lose a little speed and that may be significant to your style of sailing. (Examples were the A-Lion, Australis, Unicorn, Quest A, Catalina, Rhapsody a.s.o.). Question: Hi Ted, for us Antares fans out there, could you do a contrast and comparison of the various masts available to the Antares 44i? The sail has its centre of effort lower down, and thus reduces the heeling force created by the fatter head sail and is ideal for a foiling design. New foiling boats arrive and older second hand straight or C board boats find ready new homes with some being converted to a foiling configuration with new foil cases and rudders, whilst others are sold to the encouraging number of new sailors entering the class. Acknowledging that they can’t instantly try different sail styles in succession they however report no apparent loss of perceived ‘performance’. It has a lot more to do with entry and exit angles of the sail to achieve height and power. Hull sections and profiles continue to change. In common with all modern catamarans in its size range, the boom is fairly high above the deckhouse. A-Class AC33 ac34 AC35 ac45 AC72 alinghi Americas Cup Archipelago Raid Beachcat Cruising bmworacle BOR90 C-Class Cruising Cats d35 design Eurocat Extreme Series F16 F18 F18 Argentina F18 worlds 2009 Flying Phantom Foiling GC32 Gunboat Hobie 16 Hobie WildCat Interviews Jules Verne Trophy MOD70 Moth Nacra 17 nacra F20 Olympics Round Texel SailGP St Barth CataCup tornado … But, their practical handling off the water still proving troublesome.

But the foil building technology steadily improved and a consistent way was found of producing extremely strong shaped daggerboards from carbon composites. It worked and the boats started to fly, albeit in the hands of these sailing superstars, but techniques were discovered for getting the boats foiling for longer each time. Encontre (e salve!) In fact the most successful ‘A’ Class World Champion is the ETNZ skipper Glenn Ashby. A radical looking boat with advanced aerodynamic features and a fully carbon fabric stiff trampoline. It eventually became a strict one-design class with rules on hulls, weight and mast diameter, which accounts for the vastly different sail shapes now seen on the two boat designs. 8,3 kg for standard section and 8,6 kg for stiff section. Rigid wing type rigs were also seen occasionally. The helm station remains well protected, and integrated into the cockpit and the rest of the boat. Much design work was done over the winter of 2015/16 and two of the major manufacturers both produced more optimized designs. Ever thought about building your own catamaran? The move to produce our boats in Argentina led to the development of a working relationship with North Sails Argentina. The large sail areas caused some chin massaging but they were deemed to be acceptable, just. There was certainly no compromise, the sailplan as it still stands was considered to be adventurous enough. Power catamarans are also great boats, and although their benefits are different from the sailboats, they definitely have their advantages. These boats are in class by themselves, delivering the promise of real high performance multihull sailing. Posts about Mast Height written by tedclements. Many of the America’s Cup crews are also ‘A’ cat sailors. The International A-Division Catamaran Association (I.A.C.A.) The surface area is also identical, to avoid sail area problems when sails which are … There were two primary reasons for this; the prototypical nature of the gear on offer and the compromise to the mainsail area. Worlds 2022 confirmed for St Pete, FL - April 2022 . Initially the foils were all straight as the technology to make them anything else, without risking failure, was simply not available. Following the success of the lounge version of the award-winning Leopard 50, we are excited to announce that the Leopard 45 now comes with a lounge of her own! Formula 18, the sports catamaran for development. The requirements of a boat designed to foil mean that the underwater hull shapes are starting to be optimized for lighter wind sailing, as the hull should be out of the water when it is going fast in a higher wind. This lower drag high-aspect ratio rig, much like a glider wing, allowed and helped the boat to fly a hull much earlier downwind with the resultant reduction in drag. Then in 2005, Dutch composites expert and sailor, Pieterjan Dwarshuis, raced in the Worlds with a C shaped foil. Turns out the perceived loss of push from the reduced roach may not be all that significant a factor for our cruising boat; in a set with large headsails the proportionate effect of the main is significantly reduced along with the compromise due to a reduced roach, the limited crew and sail trimming effort likely to be available very much reduces the potential for a maximized performance main, and the relative ease of furling means the sail will actually be used a lot more. So in 2009 a rule was brought in with the intention of preventing this hydrofoiling from happening. Could you give the pros and cons of these and performance? History. The Australis hulls were pointed at both ends similar to a canoe, in an attempt to produce a drag-reducing hull. Question: Hi Ted, for us Antares fans out there, could you do a contrast and comparison of the various masts available to the Antares 44i?As far as I know there are 2 different masts available. However, the downside is that when it’s not foiling conditions, the decksweeper is less powerful and thus the C board, or ‘Classic’ boat is still king. The objectives of the I.A.C.A. 6.3 kg (14 lb) (mast tip weight) LOA: 6.09 m (20.0 ft) LWL: 5.84 m (19 ft 2 in) Beam: 3.08 m (10 ft 1 in) Rig; Mast length: 9.08 m (29 ft 9 in) Sails; Mainsail area: 16.61 m 2 (178.8 sq ft) Jib/genoa area: 5.33 m 2 (57.4 sq ft) Spinnaker area: 25.00 m 2 (269.1 sq ft) Racing; D … So, the free reign given within the ‘A’s development class spec allowed several other designs to arrive, each an attempt to improve on the other. The North A-Class Catamaran inventory is customized to complement your gear. ( Mast & mainsail Texel measurement : 14.58 sq. The reason being, that the mast itself creates a lot of profile over the rig and therefore it is very important to be able to reduce the wind age over the mast by rotating back as the wind increases. In dighny classes the Laser and Open Bic offers the possibility to the young sailors to race at the utmost level until they are grown up to master the Finn. Their ability to be altered, modified and improved will also continue to see the ‘A’ cat being used as a test vehicle for design ideas on larger boats. Currently, the modern ‘A’ cat bears a striking resemblance to its rather higher profile cousin, the AC45 . The reduced roach furling main is there for a more practical approach. Now much more of the power is pushing you forward. All the space creating and space saving ideas on the Maverick is something to marvel at. The North Sails design therefore accepts the relatively limited roach that may be supported on a series of short vertical battens. The Maine Cat 30 is a simple live aboard cruiser for weekend getaways or the cruise of a lifetime. The definition of ‘performance’ for a cruising boat may acknowledge racing sail parameters but needs to encompass and be weighted toward the compete voyage experience. So the next logical move for this development class boat was obvious and was to make it fly. The two foil types are causing a little debate within the class though. Answer: There is one mast and standing rigging configuration (height & geometry) available for the Antares that was initially engineered by Selden Spar and has been used successfully since inception. A big thank you to the builder, Chris Williams, for letting me share his work with the rest of the beachcat sailors. - The stiff section 90+kg. This rule sets eligibility criteria (max/min) such as width, length, weight, sail area, mast height and materials to be used . Cheers guys bacho. mtr.) 2.3.1.

LOA: 11.8 m. Beam OA: 6.45 m. Centreline Beam: 5.25 m. Displacement: 3000 kg. Optimized designs, where daggerboard positions and beams are moved slightly, and newer, more stable foil sections that have lower drag are now arriving, with a Z and J/Z shaped board proving more stable when combined with T or L shaped rudder tips. This rule sets eligibility criteria (max/min) such as width, length, weight, sail area, mast height and materials to be used . Mast height 46.00m/150ft 0in. If you were to break the MaintTamer in some remote location, the boom may still do its job and be readily serviced. Putting yourself in an owners shoes, and the rest of his foul weather gear, and perhaps letting go of some things that you considered ‘de rigueur’, is the only tenable evaluation exercise. This supplied much more lift and helped in getting the windward hull flying when going downwind – doing ‘the Wild Thing’ as it is known in cat circles. Formula 18 (or F18) is a class of sport catamarans defined in a "boxing rule". I'm not sure there is a boat length to mast height standard. Many home built designs turned up, and home building of ‘A’ Cats continues today, particularly in the USA, where home building tends to be more popular. The Lucia 40 is inter-coastal friendly with a mast height of the water of under 65′. The distinctive Dreadnought shaped bows of the  ‘wave-piercing’ hull design reduces the pitching moment when in waves. Some owners cut down their masts to get under this limit. FOILING: SAILOR WEIGHT: All 14 & 15 Untapered Fibrefoam: DNA Tapered Fibrefoam 6.3 to 6.5 Hounds Height: Saarberg Mast: Above 78 kg: Decksweeper 2F: Decksweeper 2: Decksweeper 2: Below 78 kg: Decksweeper 2F: Decksweeper 2F: Decksweeper 2F . This meant that conventional L shaped boards, similar to the AC boats foils, are not class legal. The more popular sailing catamarans in the 40-ft range are Lagoon 400S2, Bali 4.0, Leopard 40, Nautitech Open 40, and Fountaine Pajot Lucia 40. Perhaps one of the toughest points of sail to master for sailors new to the A-class and uni-rig catamarans is downwind in light air up to the point where you start thinking about making the transition to the “Wild Mode”. It would appear that the design curve is starting to flatten out again now as regards hull and foil design with these two boats setting the standard of performance. Which configuration will arrive at the next port first is debatable. The original masts were flexible tapered affairs as still seen on the Unicorn today. When he arrived at the Worlds, he’d simply chopped one of his older sails down along the leech, and sewn an extra bit onto the bottom to reach the tramp. DNA Tapered Fibrefoam 6.3 to 6.5 Hounds Height: Saarberg Mast: Above 78 kg: Decksweeper 2F: Decksweeper 2: Decksweeper 2: Below 78 kg: Decksweeper 2F: Decksweeper 2F: Decksweeper 2F Designed by local boat-builder Alan Cawardine specifically for fast tropical cruising, Java is equipped with all the comforts you would expect from a top-class catamaran.

A-Class Catamaran Sail Selection Chart . While nearly every catamaran is engineered to CE Class A-1 codes for open water, a 90-degree impact from a wall of water hitting a cat’s slab sides and large windows will put your boat at maximum risk. US A-Class Association. They were also made slimmer and longer, and this higher aspect ratio vastly improved the drag effects over a broader chord foil. They have low clearance. The data collected through this form may be processed electronically for the purpose of commercial prospecting only by Bali Catamarans brand and CATANA Group. Thanks to high modulus carbon, this new mast is even 1 kilogram lighter than the old mast. It was tried again a few years ago, by former World Champion Mischa Heemskerk, who was interested in exploring it again on a more modern boat design. On the latest 2016 boats, aerodynamic drag is now recognized as increasingly more important as the airflow over the boat, with the added apparent wind, can sometimes be as high as 30 or 40 knots. Following the success of the lounge version of the award-winning Leopard 50, we are excited to announce that the Leopard 45 now comes with a lounge of her own! Although all the boats measure as ‘A’ Class cats equally, the foiling/floating thing appears to irk some in a few national class associations. the long bows tend to reduce pitchpoling. A touchy matter… By necessity, sail battens in a furling main must be parallel to the mast rather than the boom, as is the case for the slab reefing sail. Misch Heemskerk won the 2016 Worlds on the F1 with Darren Bundock 2nd on the Ad3. The company always had a very close relationship with its customers and the prevailing philosophy demanded that the new boat could be handed over with confidence to its trusting owners.

The sail itself remains the same fully battened high roach cut and hidden away inside the MainTamer is the standard Selden single line reefing boom. For inquiries about the class.Charles Bueche, For race results, product news, stories etc. It wasn’t until this exercise had been run through that the height of the mast truck off the water was measured and fortuitously found to be acceptable for transiting the ICW. - The standard section: 75-90 kg. The progressive generation of. Regardless of the theory which will be debated back and forth endlessly from different perspectives and by any number of us ‘experts’, the fact remains that the recent Antares boats equipped with furling mains delighted their owners, (despite our skepticism and reluctance). Hi does anyone know of some popular or usuall mast height/hull length ratios for cats smaller than about 15ft? The Dart 18 was designed in 1975 as a One Design Class by Rodney March, who was also responsible for the design of the Olympic Tornado class catamaran. Then 2015, in the search for more power but with less sideways pressure, as required by a foiling boat’s need to be sailed flatter, he reappeared with one at the 2015 Dutch Nationals and wiped the floor with everyone, including Glenn Ashby, who was there getting ready for the Worlds a few weeks later. - Weight: < 8,0 kg for soft section, approx. The Dart 18 was designed in 1975 as a One Design Class by Rodney March, who was also responsible for the design of the Olympic Tornado class catamaran. The decksweeper was first tried on the ‘A’ cat in 1987 in Australia but proved to be unbeneficial compared with more conventional designs.
