But with a proper placement of mass a slender monohull of even 12-1 LB ratio should be steady enough not to need stabilizing help.
Location: St Augustine Fl, Thailand Small Power Tri Here's one I remember seeing an ad for in Power Multihulls. It's an interesting craft in that the bow wave is swallowed by the two sponsons, which results in almost no wake when traveling at displacement speeds. The rationale for the Landau 20 was to produce a very low disturbance hull form for cruising at displacement speeds and it is extremely good at that. Chris Ostlind Previous Member   Pragmatic purpose For a reality check and as a starting point for a boat of this type, I took some serious cues from Jim Antrim's 62' Duffy Voyager design. In attempting to design a boat such as the SurfBus that would be relatively easy to get on the water, operate by less than techy owners and drivers and have straight-forward, outboard motor serviceability, I soon discovered that there would be a price to pay for having such a narrow and efficient hull that could carry four people.
The boat could be constructed with an inboard engine set well down in the hull along with fuel tankage and other considerations for inherent ballasting. I would give away the ability to rotate the prop up and out of the water, thus taking away some of the beachability along with the easy familiarity of outboards in general compared to less common inboards. Agreed, the VT design has less in the water than the stated BOA figure, but it also has included sponsons in hull structure well aft in lieu of amas. Perhaps the real issue here is in the reference to the trimaran configuration as having "training wheels" and not the choices that have been made for pragmatic usefulness? Location: Lakeland Fl USA The Tampa Tribune just did an article about a power tri. Location: Ontario Chris, I think as long as your designs stray from simple, conventional monohulls, you will always have detractors. Fred, I'll fire back at you: What does a mono along similar lines to the SurfBus offer, that the tri does not? Where the VSV incorporates sponsons built in as part of the hull structure, I have chosen to use inflatable tubes. The point of a power tri is to have much slimmer hulls than is possible with a mono, thus reducing wave drag and reducing fuel consumption while increasing cruise speed. The point is that few would ever build a 20-1 LB boat as the wetted surface would be really a detriment to fast travel., with low power. However the multi hull operating characteristics are real , the motion is VASTLY different (QUICKER) from a monohull.
With a skinny power boat that is big enough to have good stability from weight placement (can survive a knockdown) , why slow it down with training wheels? If stabilisers are necessary to control the rolling of skinny boats, maybe skinny boats should be beamier? Added stabisers is more use full for fat box boats , where the hull lifts to severe angles as the wave hits the beam , as the leverage of wide beam adds to the rolling forces. Just watch a log and a box in a seaway , which would be better at keeping lunch down if enlarged to 50 ft and you were on board?

When making potentially dangerous or financial decisions, always employ and consult appropriate professionals. Location: Moreton Bay, Queensland, Australia Hey there, steel is possible i guess, alloy would be much better though. They could, of course, go faster, as long as one realizes that they will be sacrificing best economy for the extra speed. Both designs are for stitch and glue plywood an have simple plywood and glass box beams for the akas.

I would like to manufacture and install a hydrofoil system to emulate other boats such as the Corsair Foiler and Hysucat boat.
Can somebody here point me in the right direction to find someone that can actually design this system for me?

As explained to me, their success in achieving significant improvements in the existing cats (I think they claimed about 35%) was because the improvement to a poorly or average-designed hull by the addition of the three foils (one wing across the tunnel amidships & two smaller protrusions into the tunnel aft) is substantial, but falls away as the hull design improves. They are also used by Stealth Yachts in the USA & South Africa, with Q-speed surface drives.
BPL- thanks for that link- I'm definitely going to try to contact that guy to see how he did it. Location: Australia The only hysu-cat foils I've seen had a symmetrical foil section with the widest thickness in the middle, not like an aeroplane wing where the max thickness is about a third from the leading edge.

It is not a speed boat but a boat for economical cruising with a speed of about 12 knots with two 6 HP engines. One of the reasons I'm looking at boats as big as 25' is to get the waterline length to get me close to 8 knots cruise speed.
The Volvo MD11C is a nice little 23 HP engine, but it has been out of production for over 3 decades.
Being certified for use in winds up to force 8, the crew in the 29 is likely to want to give up before the boat does. The revolutionary ?twin tunnel? shape offers uncompromised stability along with the benefit of producing minimal wash at all speeds. Whether driving on the road or at sea, sensible people drive according to the road conditions or sea state.
It carries a sizeable, heavy battery bank, nicely centered as low as possible in the hull for the issues you mentioned and still, it uses a fairly wide set amas for ultimate stability in a seaway.
That price came in the form of the stabilization needs and the ama setup was the simplest, most direct solution available to me if I wanted to maintain the design brief positon of an easily driven hull with exceptional fuel economy. It would still be squirelly to some degree and require a good deal of care when turning in anything other than a calm sea. Parts for inevitable service would become an issue in remote surf villages, as well, compared to the ever-present outboards. It is propelled by a very serious pair of 700+ hp engines and surface drives, all out of the question for a boat such as I have designed for surfing adventures.
It seems that an adventurous fellow from Auckland NZ is planning to go round the world in 65 days more or less.
These will provide enormous stability and buoyancy when required, but will allow the craft to be a practical tender.
Better motion as the craft is not jerked level with the unlevel water surface , in offshore waves. Both of these boats were originally designed for the smallest engine possible with max efficiency while driving the boats at a 12 knot cruising speed. While both boats can take a modest inboard engine, they are designed for the power to weight ratios of four stroke outboards.
Her classic lines and style will not go out of fashion and will be sure to draw admiration wherever she goes.
Vellinga has done many powered foilers and this book has a lot of info for hydrofoil experimenters. Huppe at Stellenbosch University in South Africa to increase the performance of the poorly-performing South African Navy coastal catamarans. The book is not meant to be a tutorial on the Hysucat system but is replete with the formulas you need to calculate lift and explanations of the requirements for stable hydrofoil flight that can be applied to any number of boats including the Hysucat system.
You should be able to fabricate something yourself from stock extrusions, and experiment with different attack angles. It's shown with an outboard, mostly because it's the logical route for most, but I have a few varations of this hull that will permit semi plane motoring. If I wanted to build Zenith to William Hand's scantlings I'd have to be a millionaire, so I won't be using that design unless I adapt the hull shape to modern methods and materials. I'd be tempted to slice off the pilothouse just behind the windscreen to make a HUGE covered cockpit maybe with a table over the engine cover (if an inboard engine was installed).


The reason I'm looking at such old designs is they were designed to make good use of low-power engines.
I got some jigs that's fitting for your requirements that can be paper patterned with some mods. Parts are still available, but it's a pretty old school setup, which may or may not be appealing to you. Add that to the fact that if you plan on gunkholing any, a straight inboard may give you some grief.
I thought he was trying to sell these units as a dealer, but I just talked with him today, and he indicated there was only one built by some guy down in Miami. What I would say is that a car capable of more than 180 mph will have safer tyres, suspension and brakes and better able to stop the vehicle at 30 mph than a more mundane car.
A totally calm sea state does not, typically, go together with good surf conditions; The principal reason for the design. Why would I try to get a much more slender design to do similar things without the inclusion of amas for stability? Modifications to either boat for inboard power are within the scope of the designs as they were also meant to take electric drive systems.
She is designed around the Yanmar 1GM10 with 9 hp max at 3600 RPM and 8 hp continuous at 3400 RPM. The designer of the Javelin has also developed a set of foils for this cat, so you could e-mail him as well.
I made one from glass years ago and stuck it half way the length of a tunnel hull, it was about 2'6 wide and 6" , maybe an inch thick. I'd hesitate to put a heavy 20hp inboard into a boat that was designed for a modern 75-250hp outboard.
Of course you can do the Bluejacket too, and I know Tom would just love than inboard being installed in his boat. Of course most displacement hulls do have some rocker in them and reduces some of the potential of wheel dings for shallow water use, but eliminates the ability to plane.
It also has only one guy onboard and he gets to sit well down in the hull in an enlosed cockpit. It has a certain dock appeal, if you will, for other uses beyond its original design application and it could be used, comfortably, in the manner I indicated in an earlier posting when I first showed it. Anything more than a flat calm`most boats stay in the marina, but those owners who do venture out, appreciate the safety engineered into their craft. I just had to recognize some basic issues when I started and this boat became a good example of design thinking. It gave more lift, but not more speed as far as I could tell, I know there was a fair bit of extra lift because the boat banked more in turns. Alexander Sahlin has tested his and several other concepts in all conditions for many years. The aestedics can be changed to suit any "era" if a perticular style is desired, so focus on an efficent hull and also on a build method you can live with. Below these speeds, you don't need much power, but to "climb the hump" you need much more HP or have to cheat with clever hydrodynamic tricks.
He is very skilled in hydrodynamics, aerodynamics and carbon fiber composites and knows what he's doing. For example, you can pick one of the old Billy Atkins harbor launch designs, which will be efficent, but it'll also be twice as heavy as necessary, if a modern build method was employed.Sso be careful what you wish for, as you'll have to pay for, cut and install all those extra pounds. We also got out on the water last weekend and gunkholed ourselves, between all this crap of a marathon winter of cold, ice and snow. The "Jersey Blue"  (Atkins) is a good example, where a 25 HP inboard might get you 10 to 12 knots with a 40 - 50 HP inboard jacking this to a max of 17 - 18 knots. We had the water to ourselves and also did some geocashing on the barrier islands, a cool hobby for old folks too. Jesrey Blue is a carvel build and will need some upgrades to bring it into the 21st century, but not an unreasonable thing to consider.
