Cunningham, mast rotation & optional foil controls just pulled under the trampoline But Maas didnt care, because he was going to replace the combustion engine with a 10-kW permanent-magnet AC (PMAC) motor before extending the shaft by 18.1 (46cm) and attaching a 9.25 x 11 (23.49cm x 27.94cm) prop to suit his purpose. Its just ACX fir plywood from the lumberyard with a couple of coats of WEST System 105 epoxy, Maas explained.

Without foils, Gizmo manages 8.5 knots at the same power draw, which constitutes a 30% reduction of efficiency. Built in two halves that he machined flat on his 3-axis CNC router (a converted surplus CNC fabric cutter from Boeing), they then were bonded to each other in the molds with ProSet LAM 125/226 epoxy, initially cured at room temperature and post-cured at 140F (60C) for eight hours after being removed from the mold. He was kind enough to accommodate my request for a ride, which added about 190 lbs (86 kg) to the payload. One method is flexing and twisting foils with foot-pedal-controlled ailerons, which Maas used on the Hobie. Maas plans to close that cavity with a foam plug. To my surprise, there was no damage at all to the hull or the box for the dagger board. . The spectacle of a flying catamaran, be it an Olympic Nacra 17, a GC32, the recent Americas Cup 50-footers, or, Not everything that flies is destined to scorch around an Americas Cup course. Ill help you with some of the design work. Aside from foiling Americas Cup sailing catamarans and International foiling Moths, Bieker has been working with local public-transport authorities on fast-ferries and is involved in the design of a fully foiling passenger ferry (see A Foiling Ferry for Puget Sound, PBB No. They are small foilers, monohull or multihull, for a single handed and they have a central inverted T-foil and another inverted T-foil in rudder on the same line.

Hailing from Seattle, Washington, he started messing with boats as a kid, graduating to OK Dinghies, Lasers, and Finns as soon as he was strong enough. > CONTACT. Sail area: 13.94 m Mothquito, Surficat and IFS are registered trademarks.

You dont need a crane to step the mast and the cat can be launched off the trailer, so its very versatile., Cool Runningss owner Thorkild Juncker trails his boat and their support RIB on the same trailer around to the various European regattas behind a normal car or van. With all-manual controls, its not fly-by-wire but fly-by-seat-of-your-pants. Cruising speed is 12 knots at 5.8 kW. The sophisticated deck plan provides clear control and minimal air resistance. With increasing speed, the center of lift moves aft, which keeps Gizmo in balance. But while the ETF26 demonstrated her impressive and nimble performance in the light, my hosts were not to know the level at which theyd be tested 24 hours later when a vicious 60-knot storm, complete with torrential rain, hail and lightning, swept the lake. > F1X A-CAT FOILING CATAMARAN Seven knots of true wind and a few quick pumps on the mainsheet was all it took to have the 8m cat rise up onto her foils and slip downwind at 16 knots. . Survivsl mode of boatspeed. He can make it bank any way he wants to. After putting in some test miles, Maas also added a canopy made of 1/4 ACX fir plywood strengthened with a layer of 180 g/m2 of S-glass/epoxy. Where is it? . In-water testing began with a 15-hp gas outboard bolted to the Hobie and some plastic drums filled with waterstrapped to the deck to see how much power it would take to [achieve]foiling takeoff speed. Photo: Gilles Morelle. Found that the design has a lot of power but it can efficiently be de-powered (thanks to efficient wing-sail set-up and rake differential)- allowing for sailors with a wide range of weights to be competitive.

Top speed: 31 kn In Maass island workshop, Gizmo dangles from the rafters between farm equipment and Ariel, an International One-Design sloop awaiting restoration. After going by the board, this two-cylinder Tohatsu was salvaged, but never properly flushed, so the innards corroded, turning it into a hunk of scrap metal. Stability foiling both upwind and downwind was surprising considering the sharp choppy conditions. Photo: Matt Sheahan. With its low weight and its state of the art hydrofoils, it is airborne in winds as low as 2Bft. So it goes very fast. He also worked onother peoples boats, repaired them, built rudders and daggerboards, did anything to pay for his racing habit. To get to higher speeds, he said hed have to go beyond trying a few off-the-shelf props. Despite the horrendous conditions, they and two of their sisterships survived the pasting. The line-controlled paddle wand mechanism automatically adjusts the foils angle of attack. For the aft foil, Maas repurposed a Moth main foil with an MH 32 airfoils profile, a piece of gear hed kept in his shop after selling a Moth hed built for himself to participate in a World Championship in Hawaii. It feels counterintuitive at first, but its details like these that you need to learn and its exciting., For the construction of the ETF26, Dick set up an assembly facility called Absolute Dreamer. Of the two key features that help this, a simple deck layout and foil controls are one, the ability for the boat to ride close to the water, at around 50cm, is another. All our foiling F1x A-class catamarans come straight, ready to race and Mischa-tuned from our factory. Draught: 1.20m (3ft 11in) Thats just what you might expect given that we were sailing the ETF26 on a lake that is famous for its lightweight flyers on the eve of the worlds biggest lake race, the annual Mirabaud Bol dOr.

Height sensors and flaps to regulate the flight height, since its V foils automatically regulate the height. Maas wanted to keep Gizmo on a float for quick launching and to avoid the need for toxic bottom paint. Following our two-part story about fiberglass disposalor the lack thereoffor end-of-life boats (Professional BoatBuilder Nos. The Mothquito is a high performance catamaran racer.

IFLY15 offers freedom to fly alone or in pairs. Its the job he ended up doing for more than 20 years with his own outfit, Maas Boat Company (www.maasboats.com), which he started in 1978 in California and sold in 2001. We can be travelling at 35-36 knots in flat water but drop the speed down to around 25-28 in waves in order to make the boat more controllable, he continued. Basically, it was a long series of major changes and adjustments that eventually started to taper off as I ran out of changes that needed to be made, and things actually started tofunction in the proper way.. Leaving a zig-zag trail of foam, Maas demonstrates Gizmos maneuverability on foils. It was clear this is an exceptionally slippery boat. And on Lake Geneva, no tide could artificially inflate the figures. The wands are built from old carbon fiber windsurfer battens with attached pieces of PVC sewer pipe as paddles to keep the end of the wands at the water surface. In the DNA design team Pieterjan Dwarshuis, Mischa Heemskerk and the renowned Dutch industrial design engineer Rudo Enserink worked closely together to create the perfect foiling A-class catamaran. At some point he helped 1984 Olympic Gold medalist Bill Buchan build fiberglass Starboats and a cold-molded 3/4 tonner that they raced to victory in the Swiftsure International Yacht Race and a second-place finish in the 1978 3/4-Ton Worlds. As foiling progresses, more and more fans and sailors want to experience the sensation of flying, even if only once. Only slightly resembling its earlier gasoline-burning incarnation, the modified outboard shows the PMAC electric motor, the 18.1 (46cm) shaft extension, and the wand-controlled Moth foil that carries the smaller portion of the load while foiling. This field is for validation purposes and should be left unchanged. Wanneer u een website bezoekt, kan deze informatie in uw browser opslaan of ophalen, meestal in de vorm van cookies. So philosophically, Im coming around to the idea that theres a lot of good equipment out there, either just languishing in somebodys basement or backyard or going to the dump at some point. As a former racer and stickler for clean and functional boats, Maas doesnt skimp on quality or performance, so he scavenges for the good stuff, which takes skill, patience, and a few good friends. Construction He came around in one of his little high-performance powerboatsand we started talking about foiling. My ideal motor would have probably been a 20-hp [15-kW] with a hydraulic tilt-and-trim mechanism as a way to control the foil angle, but that did not materialize. Extra: All measurements according to IACA Class regulations. Total weight: ca. The idea was to create a SIT & FLY foiler, that is to say a boat with foils that practically flew alone, and endow it with an exceptional stability so that any sailor could fly easily, regardless of their physical or technical preparation, also allowing them to access into the competition with foils so far suitable for only a few specialists. iFLY15 has a length of only 15 feet, is easy to transport, quick to get ready to sail and can be easily slipped from the beach using a conventional beach trolley. Extended version on your desktop computer. Was positively surprised with the level of detail and building quality of the whole package, especially the foils. After that, Maas designed and built International Canoes, and won a World Championship in 2011 to go with two runner-up finishes in 2014 and 2017. All foils used on Gizmo were molded in female MDF molds, but for the main foil, Maas used a simple solid-fir core he covered with 15 layers of standard-modulus 200-gm2 (5.9-oz/sq-yd) unidirectional carbon fiber and one layer of 45 plain-weave cloth carbon on the outsideall surplus from Boeing. I actually have to foresee the use for stuff that comes over here, Maas said at the end. And it becomes, yeah, some sort of scary. To port theres the GPS readout, the hoisting line for the main foil, and the cleats for the ride-height adjustment lines that lead to a threaded spool that changes the articulation setting of the sensing wand and, by extension, the main foils angle of attack (AOA). Code 0: 26.50m (285ft2) Lake Walchensee.

/ 6 Knots. New individual color in front

Best water body for sailing in Bavaria, South Germany.

There are more-elegant solutions for sure, but on an experimental boat that small and simple, electronic ride control is not a viable option, adding too much weight, complexity, and expense.

Never one to seek the limelight, Maas is not a household name in the international boatbuilding industry, so lets start with a short introduction. What a piece of kit! Another impressive performance by what is essentially an overgrown, upmarket beach cat. The shape of the main foil is close to a NACA 63-214 profile and was modified from Biekers original dimensions by Maas to give the flaps on the trailing edge at the wingtips more authority in roll control. The owner of Cool Runnings is a prime example of just this. With a dynamic beam of around 2.5 m, which usually coincides with their hull beam, these foilers are much more stable than the 2T foils, but in them the use of trapezoids is usually common to compensate the heeling, which not everyone likes and less at high speeds. Even here we were slicing along at just over 10 knots. Port Townsend boatbuilder Russell Brown, himself a prodigious recycler and reuser of discarded boat parts and kit (see Outside the Box, PBB No.
