Location: Marina Del Rey, CA 3 sketches as requested Graphics you wanted. Note the bi level, rigid sails, -wings- considered fore, with a ketch style single mizzen mast near the stern.
The really nice features of this layout become evident in plan view, with the diagonal cross-braced steel trusses spanning through cockpit and habitable areas. Under high wind conditions with max sail foil exposure, leeward side pontoons are air bouyed, adding lift to the 'loaded' submergence depth, while windward side will have water ballast to keep pitch-neutral.
One other control consideration is to add horizontal rails (that attach to the outrigger arms) to the torpedo shape. While simple in concept, obviously this becomes rather daunting tasks in real design and construction applications.
Location: netherlands how about a mind controlled swath that senses its pilots emotions and can react in bio feedback mind control technology? Location: Marina Del Rey, CA jet propulsion vs sail This is best underwater, right Yip?
AdHoc I agree, but with sailing, where stability and consistency of inertia become prime, not speed, underwater mass is obviously preferable, right? Subject to heeling comments, I'd like to see torpedos as long and as narrow as possible for max. The smaller my cross area underwater, the stronger the cantilever arm, the denser and more structural each pontoon must become. It is my belief -from conversations with builders- that these vessels become the natural evolution of luxury recreational yachts, very soon for the above reasons. Propulsion concepts: Instead of a simple ducted propeller, (as in waverunners) how about geared, triple impellers? Third and final fan very small blades, extremely high pitch adjustment for nothing but highest propulsion -and smallest diameter tube.

Similar in some respects to the HYSWAS concept, lifting body vessels rely on a combination of bouyant and dynamic lift to achieve the desired running height.

When making potentially dangerous or financial decisions, always employ and consult appropriate professionals. Location: Italy Free standing mast on a small boat I'm a Young Designer and i'm working on the structures for a 6 meters cat boat with a free standing mast.
From the RM 30 deg I've calculated an equivalent force on masthead (8m ) that's 110 kg with a safety factor of 1.5.
Anyway i' ve some doubt about the wishbone rig and i'm feared about the load coming from the boom. Location: Lakeland Fl USA The wishbone boom will place a deflection load on the mast in a higher location than a conventional boom arrangement. Another plus is you haven't got a draggy wishbone a third of the way up the mast, right where you want clean air flow.
Location: 59 45 51 N 019 02 15 E I have sailed with two freestanding mast and a special boom since 1982.

If you haven't already, go to my website for a complete description of free-standing masts.
I have to think that they will build more than one, so the the choose should be driven from production.

Yes, huge obstacles certainly are presented, but within the existing considerations of what is possible- with current technology? Since we're in water, no compression change differentials, just adjustable blade angles of attack. This will answer about 80% of your questions immediately, and almost all will be not possible, with the goal which you wish to achieve.
They differ from the HYSWAS in that most of the dynamic lift is produced by the underwater body itself and not all from appendages attached to the underwater portion of the hull as was the case with the HYSWAS. However if your hull has narrow stern sections, then this option is of little use - you need plenty of beam (a la cat boat design anyway) to make it work properly.
Again, BF, trim for heeling, toeing and list would be adjusted according to buoyancy of each pontoon. Like a biplane, lift -or in our case moment- can be augmented (venturi-effect) from one airfoil over the other.
If we can make an F117 Nighthawk fly, as aerodynamic as a brick, then modest computer-controlled pontoon modulation for the Seaskimmer is realistic.
The wishbone will not exert a higher horizontal pressure on the mast than a boom nearer the base of the mast.
I believe that both are now owned by universities in California, donated and used as marine biology research platforms. Although the wishbone at a higher mast location is in a less advantageous position, it may not exert as much pressure as is first anticipated. As always, I've included a .hul file for those who wish to take a look at the hydrostatics, or to develop their own version. These subsurface torp tubes can be ballasted either with seawater, or buoyed by air to adjust loading and dynamic attitudes. Another reason is that the force of the boom is not a horizontal one and the lower part of the mast will have a tension component to counteract the compression component.
If extensions are hinged to main vessel trunk (hydraulics) the swath can adapt to sea conditions instantly as req'd. Also, there is a discussion group for builders and users of the Mouse family, and for those interested in the designs at Mouse Boats. I think this is still the first design of this kind available freely over the Web.
The drawings are zipped and in .dxf format, and show various views including the developed panels - if you fancy the real thing, as I do, why not begin by making a small model? Let me know if you're interested in sail plans and modifications for camp cruising, as I believe this hull is just about powerful enough for a small cruising sail plan, and I've got some on the drawing board. It would have to be small, as any boat that rows as well as sails is a compromise one way or the other.
Incidentally, I've called it a trow because it's form is based very loosely on a traditional British flat-bottomed type, the Fleet trow - however, the old boats were heavily built, and had no rocker. Also look out for the on-line books he's in the process of putting up - I think the link will be from his Cheap Pages.
Andy has put up the design as a backdrop; save the image, and you have the design.
He says the boat works pretty well in most conditions, but sometimes makes him feel seasick in in waves and a light wind.  Sampans Fancy a real challenge?
Just start off by ignoring the first sentence of the second set of instructions.
I've paddled one of these things, and I can tell you that there's nothing like the suicidal balance of these little boats. It's interesting that although thought of a primarily Welsh and Irish in origin, these craft were - maybe still are - launched from both the English and Welsh sides of the lovely river Wye, and I understand there's an English professional soccer team that uses one as a mascot.
Take a look and see what you think - my guess is that some people may build this astonishing little craft as a very low-cost motor-sailing cruiser.


From a book about converting lifeboats into yachts, I gather that traditional sailing lifeboats were not normally expected to sail upwind - I wonder how this one would do against the wind?
If you aren't one of the lucky people who have their own ShopBot, my hunch is that the ShopBot's suppliers may be able to put you in touch with someone who has one and is willing to cut out you sheet material for a reasonable fee. As a Brit, I'm delighted to be able to publish something that originated in my own country for once! You will have to contact the author to receive details of how to download the plans. Many are closely based on traditional types, including rare traditional hard-chine UK types, and a few from his own fevered imagination.
There are links to pages where Hulls can be downloaded on the drawings page, and also in the Software section below. Some people think it's a lot cuter than an Optimist, and it's probably close to being the perfect two-sheet dink. There are also links to designs for a folding kayak, and a conventional kayak, and an excellent treatise on how to do tack and tape boatbuilding. The designer says it performs well, but may be a little tricky in the building. Hans, an experienced canoeist and enthusiastic woodworker, says it works well, is stable and tracks well. Hans designed the Marak using Gregg Carlson's Hulls program (see below for much more on this software). But I'm still rather torn about the issue: how do you feel about people who hide perfectly good designs away where no-one can find them or use them? I hope Mr Beavis, Mr Sleightholme, and their publishers of twenty-odd years ago won't mind too much.
I really liked this and used it for my top-of-the-page logo, and re-drew it a little longer and beamier using CAD for the generation of a century later.
I gather Munroe once told his friend and student Vincent Gilpin that he would 'cheerfully sit up all night to cut out one superfluous rope from a sail plan', and from these drawings you can see that he meant it. Those that have been designed are intended mainly as a piece of fun and shouldn't be taken too seriously. I'm sure the one-sheet design brief is impossible - but if you're going to tinker with something, it might as well be as cheap as chips. This is the now famous Herb McLeod One-Sheet Skiff - read the 'Big guy goes frogging' link for a smile. I haven't the slightest idea what he does with the frogs, but I'm sure my mother would be shocked if she knew about it. Another single-sheeter drawn by myself is available only as a series of coordinates that you have to plot on the plywood sheet. Use a batten - a thin, straight and flexible piece of wood - to join the lines in smooth, fair curves.
Mark them and cut them out and after that it's a straightforward tack-and-tape job with a certain amount of framing.
To me, it's a more useful and serious looking one-sheeter than I thought possible, and should really be thought of as a kind of coracle rather than as an attempt at a one-sheet skiff, and it might even be useful as a tiny tender. You could work entirely from the gifs and the coordinates file without too much work - I'd start by squaring-off the ply material and then plotting the corrdinates.
If you build this boat, please let me know and, if at all possible, do please send me pictures of the finished craft in and out of the water, and perhaps a few notes about what you use it for.
