A selection of well-known design schools from around the world that offer Courses in Transportation Design. A report from the 2013 edition of the Politecnico di Milano Master in Yacht Design, recently concluded with the development of 15 different projects and the construction of a hydrofoil sailing boat.
First launched 12 years ago, the Master in Yacht Design provides the international boat market with qualified professionals capable of leading the design and production process of any modern sailing boat or motor yacht. During this edition particular attention was given to the labs hands-on activities, which led to the development of 15 projects as well as to the construction of a sailing boat equipped with hydrofoils. Thanks to the support of specific contributions, including seminars, focused visits, instrumental labs and meetings with industry professionals, two Design Workshops developed a number of solutions based on two distinct briefs: a 50-feet sailing boat and a 80-feet motor yacht.
In the sailing boat workshop ample space was given to the conceptual development, with a small number of creative constraints and an emphasis on the exploration of innovative design solutions in support of sustainability. Starting from the individual design briefs, each participant developed the main volumes and waterlines, the interior space organization, the upper deck layout, taking also design decisions concerning the onboard systems, the sailing rig, the construction and finishing materials. For the motoryacht workshop the teaching staff chose to give more space to the detailed development of solutions focused on feasibility, in order to achieve a production-ready design definition level.
The final internship experience, which is currently taking place at shipbuilders and professional design studios, will allow  students to further advance the design knowledge and experience gained from the Master Course, in view of the final exam discussion, scheduled for this April. Another achievement of this year’s Master edition was the design development and construction of a sailing boat with hydrodynamic foils, conceived for a two-member crew. This project also drew from the five-years experience gained from the experimentation with composites for nautical applications. This allowed to build the hull using sandwich-structured composites made of linen,  cork core and vacuum impregnation epoxy resins.
The hydrofoils located on the craft lift the hull up and out of the water, thus drastically reducing water resistance and increasing the boat speed. The project was finalized with the adoption of a wing sail with variable profile, capable of generating a high efficiency asymmetrical profile, which at wind speeds of only 8 knots allowed the boat to sail twice as fast.
Twelve years of history represent an important mark, not only from an educational perspective, but also when looking at the shipbuilding industry, which over this period of time has employed many professionals coming out from this school, leveraging their competences and contributions in term of culture and design innovation.
The figures of this anniversary are particularly remarkable: as of today about 300 professionals have been trained, with over 5,000 hours of lectures, 1,500 hours of design workshops and 3,500 hours of internships at local shipyards, design firms and other companies working in the industry. Furthermore, over the course of the past years the School has established a dense network of collaborations and exchanges with manufacturers associations and other institutions active in the recreational boating industry. This design is cut from top quality Vinyl, rated 6 years outdoor durability, fade resistant indoor and waterproof.

IMPORTANT: Please read the following terms and conditions before deciding to make your purchase. Location: USA 14' concept sailing W The passengers in W boats sit, ride and stand in them with one leg in each hull, with their feet reaching the bottom of the hulls. Location: Ontario A single rudder could be enough, of course, depends on size.
Location: Sydney Australia I'm curious, why is it more stable than a 3' wide scow type? There have been catamaran dinghies out here (Australia) where your legs go into the hulls for years, how'd you get a patent on it? Location: Sydney Australia But what makes two hulls more stable, if everything else (ie disposition of bouyancy, C of G, metacentric height whatever) is the same as a mono? Other issues are that the cat doesn't plane, and the two bow waves will interfere with each other more, so there's less reduction of wave drag than with a wider cat.
Location: CT, USA I sail small cats a bit myself, but in this case, it seems that it looks stable if you keep the center of gravity low. W boats don?t need a centerboard since their straight and relatively deep hulls get the job done.
I just got an order from a distributor in NZ, so in a few months there will be some W1 models (10? paddle craft) to test in your part of the world.
Thanks for the comparison with a Hobie cat -Coming from a Hobie sailor like you it?s a compliment that shouldn?t be taken lightly! Controlling lateral stability means you want to keep the boat from tilting too much (it can be bad in terms of directional stability) and from overturning in extreme cases. Keeping the CG low is one good strategy, and having a wide beam or two hulls at a great distance apart from each other is another good strategy. But when for various reasons your boat must be small and narrow a third strategy can be to use the passengers as ?active ballast?.


The hull offers good resistance to the additional weight due to its volume, and doesn?t roll easily because of the water pressure on its side. Our legs are powerful and sensitive, and do a great job in shifting weight from one hull to another both quickly and precisely. Riding is the best position for that, but standing is a good position as well while sitting with legs forward is not as effective.
I understand what you're saying about the planing capabilities of cats, but what if the twin hulls are flat at the bottom, like skis?

It looks like the W approach has something to offer as long as it's a small vessel carrying 1-2 persons and nothing much besides that. Location: Sydney Australia Ok, Icetreader, I should have worked out that a greater % of the volume is further out. My understanding is that the main problem is that efficient planing depends on having a wide surface, not a long skinny one like a cat hull. I also agree with you about the value of standing up, it's a very effective way to shift weight. At larger heel angles, the higher bilge of the mono rises above the surface, and if the monohull doesn't have much freeboard, the lower rail starts to go under.
Location: CT, USA Micro (as in small) nautics (as in water vessels or something of that nature)! When making potentially dangerous or financial decisions, always employ and consult appropriate professionals. Most boat design software is so complicated you don't know where to get started - which is the same as most software. The worst part is when the help doesn't work or solve your problem and the customer service is lousy. As I mentioned on the previous article, I had searched everywhere for boat design software and finding 3D Boat Design was a wish come true.
You see some companies, on purpose make boat design software almost un-useably difficult so that they can rack up costly support tickets and squeeze as much money out of as possible. However unlike these other companies, 3D Boat Design has a full range of tips and an FAQ with support included with every purchase. I then decided to test my hull, because the software has great hydrostatic calculations that tell you how to improve your hull.
The great thing about it is that it accommodates amateur designers like myself and professionals who would make full use of its many features with things like the Delft series resistance calculation and The KAPER resistance method.
As well as having great fun designing your own sailboat you get free upgrades and can use it on as many computers as you want. So, in conclusion, regardless of whether you want to build a boat yourself or just design boats as a hobby or business, the 3D Boat Design Software is the one tool you can start with and you won't be disappointed!
It is possible, like I said before, to use this boat design software to start your very own boat design business.
Just create a design and turn it into plans to be sold as a boat building kit, just like so many others are doing.
This is powerful boat design software and yet simple enough for a novice to use and be successful with, right out of the box.
It is hard to imagine being able to get your hands on such incredible software at such an affordable price. I fully recommend this software to anyone wanting to mess around with boat design or start your own professional boat plan business.
I don't know enough about multihull performance to tell if these was any photoshop involved in this..

Location: Sydney Australia Going back to the very beginnings of catamaran sailing large plates were put at deck level on the bows of the hulls at some angle of attack. Worked for some, but if the nose dug deeply into the back of a wave for instance that could cause the bows to be pushed deeper into the water and actually cause a pitchpole.

Location: Arizona, USA Hello, My name is Evan Stufflebeam and I go to high school in the desert of Arizona in the US. Location: Arizona, USA I was wondering if anyone knows how quickly ETNZ can get the boat up foiling? Originally Posted by EvanStufflebeam I was wondering if anyone knows how quickly ETNZ can get the boat up foiling? Here is a pix of TNZ and Luna Rosa(which uses a mainfoil system closer to Oracle than to TNZ). Also a wing compared to a normal soft sail gives more stability in aero power and in control, it does not move similarly in bending or twist to a flexible sail. Actually it is more impressive to view the winged AC72 from a distance because on board, you have the impression that everything controls itself.
Even bearing away (doubtful translation) in 14 knots for the very first time, there was no slaughtering; the feeling of security was a pleasant surprise. I have only sailed with a wing once before on an Oracle AC45; it is in no way the same size.

We used to have one, they were great, but I would have thought they'd also bee prior art?????
In this case, with only 3' beam the cat is only as beamy as many monos so the buoyancy forces created by the lee hull may not be any greater than the buoyancy forces created by the lee side of a single hull of similar width - and most 14 monos are wider.
Also, I'd advise checking out the Go-Kart seat on the Sea-Doo 3D, it's a good model for an interior seat with steering wheel and a motor, it ought to perform well in such a config. The skinny hull presents a low aspect ratio surface to the waterflow, and just as in rigs that's not very effective. They are much better at planing at moderate speeds than a skinnier board, whether it's a long skinny board or a short skinny board. Your all geared up to start transforming a photo with Adobe Photoshop or making budget sheet with Microsoft Excel, but then the problems start.
It is used by 200,000 amateurs and professionals, who all use it to design their own boats in the simple to use 3d environment. Well, as I was building this website, I was suddenly struck by the possibility of designing a boat, instead of reviewing loads of other boats - just for fun, I wasn't actually going to build it, but I just wanted to make all sorts of wacky designs, just like when you doodle as a kid!
It was only $37.95, which is about as low as you going to get with software of this calibre and topic.
So I learnt all about the software, which wasn't hard as it has a very shallow learning curve and I got the gist of it very quickly.
I first had to make the shape of it, which wasn't very difficult, because 3D Boat Design has simple 3D scaling, moving and rotating of shapes. It ended up looking a bit like a GP14 - probably my unconscious mind working in the background!
Usually, you are told just the opposite as the software developer tries to justify ridiculously overpriced programs. Where on earth did you find this picture, and have they really been flying the center hull since off the right hand side of the frame?
I don't see them letting the main out, which I assume would be the right thing to do if you're about to lose it.
The sad part is that while it can sail at 68knots on starboard tack, it has to lower it's rig and be unceremoniously dragged back upwind on port by a RIB, but that's the price you pay for ultimate speed. I stumbled upon the Volvo last year at about this time and have fallen in love with sailing of any kind since. Does it take quite a distance at speed or are they able to get it up in a short span like what it will be on the race course?
There's probably more volume out to leeward, but how much will that increase stability compared a Sunfish or Laser? Over the summer I was in San Francisco and sailed about 30 feet behind Jimmy's AC45 on a sailboat tour around the bay.
They both require hiking, so if you don't want to hike you'll need a much smaller rig unless you are vastly more stable.
Over the past week I read through most of the pages on this blog as I think about AC72's all the time, and you guys answered any questions I had throguhout all of it.
