Large volume flat-water marathon racing kayak, for paddlers of any weight, especially those over 170 pounds. Our most current wildwater design, the X-5 is truly made in America, having been designed by William Nutt, an American paddler. Concave sections in the hull beginning at the wing give this boat very little wetted surface area, without being radically unstable in whitewater. Location: St Augustine Fl, Thailand Electric Marine Propulsion, Rim Drive Technologies Have you guys given considerations to the 'rim drive' propulsion units?
Location: United States Chinese Junk Yobarnacle, did you just call my future dreamboat Chinese junk?
I need high tech design-engineered boat, utilizing proven low maintenance components while being mindful of my carbon footprint. Location: United States BTW, I read that our word Yacht came from Dutch Jaght from old Dutch Junko from Chinese Jun (boat) or Javanese Djong (boat) among other explanations.
I will be happy to dream about my junk rigged, unstayed-aft-mast, motorsailor, powered by Chinese junk hybrid propulsion, navigated by Chinese made Garmin with Chinese made iPad. Sailor Alan, do you know where I can find transmission gear efficiency of keel drive, sail drive, outboard drive and inboard drive? I am thinking, affordable long term live aboard cruiser should be made with Chinese parts, designed sustainably, assembled with local labor. Various navies have experimented with ?shark skin? and ?Dolphin Skin? on their hulls, but both are dynamic, so a little bit hard to do mechanically.
There is a ?engineering handbook? that lists all the efficiencies for chain, gear, toothed belt reductions. I don't think there is a systematic chart of propeller drive form, but some ?rules? do apply. Slow boats, hull speed, use long keels with imbedded shafts, probably because longitudinal stability is important, and skin friction is not. Be aware, Lithium Iron batteries have a very delicate manufacturing process, and a poorly controlled one leaves particulates of Iron in the gel contained within it. Chinese Photovoltaic panels suffer the same issues, cheap and poor efficiency, again usually a result of poor purity in the ingredients.
I have had bad experiences with the small (high speed?) diesel generators from China, not starting when needed.
Many Chinese Lithium batteries have proven themselves in electric bicycle applications worldwide.
Even best iconic US product, Apple's iPhone, is manufactured in China along with all IBM servers now. Location: Mexico, Florida The food preparation area doesn't HAVE to take up permanent space or be a designer galley. The one exception to semi-permanently installed, is a single burner sea-swing stove keeping the coffee hot.
Location: Mexico, Florida oh, instead of just batteries, check out super-capacitors. If I was to sail with my son or my brother, then a 24-30' boat with camping-like set up would be sufficient and a single table for cooking and navigation is good enough.
In my mono sport fishing boat, I can cook under hardtop on portable butane stove even though it has a standing galley in cabin. The main cabin of the Albin 'Intrepidos' formerly had vee berths with a table, a full galley and a standup head.
The new central hull would have a cross section a bit like a 'box keel' but where the 'keel' comes up to the arma level.
This makes the central hull about 8? wide, and with enough flair to stow the floats under the extensions when on the trailer.
I would go for a short mast, perhaps 10-12? high to launch a paragliding parachute for sailing. Good advice about the gimbaled single burner, ours is an old kettle with a single burner brazed on the bottom, and hung from a wire hook.
For the regular sea-swing, a pyramid style food grater brazed to a small circular metal plate that fits inside the pot holder, makes a good cabin heater. Location: United States Fast Economical Boats and Diesel Sailor Alan, that is a one heck of a trimaran. My preferred hull shape is double ended fat dory hull above water line with modified Seabright hull below water. Yobarnacle, any advice since you should have more experience with this type of hull (bartender, trawler and barge).
The true live aboard cruiser for a retired couple or a small family should be sufficiently furnished for living extended period away from the home in reasonable comfort. Location: Mexico, Florida I'm not planning to cross any more oceans by boat.
When picking a boat to build, you need to think of the end result of how it is to be used and pick the characteristics which best meet those needs. Sailing is great, I've been doing it all my life and every time I launch a boat, I get that magical feeling.
Of all the hull shapes that people use as boats, the box boat is the easiest one to build because it is literally just a box with a curved bottom.
Box boats are incredibly forgiving as to how you configure them, the long flat sides sort of work like full length keels helping to track. The class keep the boats as identical as possible so that the competition is between the skill of the crew.
The class competitors engineer completely different sailboats so that their boat design is a significant part of their ability to compete. From a class perspective, it really doesn't matter how fast or slow the boat is because the point of a class is to have a common set of parameters to use for creating fair competition. Because of the social nature of competing with friends, it really is nice to have slow boats. Another great advantage, if we are about to collide with each other, it is easy to reach out and push off the other boat so we don't damage each other. Once you discover the boat building hobby and how easy it is to make boats, and you realize that no single boat will be perfect for every situation, you become hopelessly addicted to building boats (just like me). The puddle duck is just short enough, that she can stand upright against the wall of a typical garage so when you want to work on the next boat, you can just put her there, out of the way. I know of one duck that has a shelf that stands inside the upright hull so the space is still functional storage area. Since plywood is typically 8 feet long, all the pieces to make a pdracer hull can come from single sheets of plywood. The max width for loads on USA highways is something like 8'6", so the puddle duck is just short enough to be carried sideways like this. A skinny kayak type boat is easy to carry around and store but the problem is they only carry 1 person. For new duckers that have never sailed before, they can invite an experienced sailor aboard to help teach them how to sail.
For some duckers this will be their only boat so being able to use as a recreational boat to take another passenger and teach their kids to sail is an important factor.
Generally speaking, there are 2 main types of boat hulls: Displacement hulls, and Planing hulls. It has a curve shape to it's rocker and as you sail, a wave is created, starting at the bow. When the trough of the wave extends to the full length of the hull, that is called sailing at the hull's displacement speed. The most common displacement hull shape has a fair curve and tries to fit that trough so as you sail inside of it, the rocker will match the trough and flow the water around it evenly. A planing hull is shaped like a typical bass boat or jon boat, it has a curved entry and then a long flat run with an abrupt corner at the stern. The way a planing hull works is that as you apply power to the hull, it will create a bow wave just like the displacement hull. However when you apply more power, because of it's flat hull shape, it will rise up on top of the bow wave, and then start to skim on top of water, which is called planing. The compromise of planing hulls is that if you push it at speeds below planing, then the stern transom will drag in the water and create large amounts of resistance. The Puddle Duck's rocker is a hybrid (semi-displacement or semi-planing) that borrows from both planing and displacement types. Before launching the pdracer class, I spent a year testing the rocker shape on one of my other boat designs. NOTE: Measuring for class legal racing, the tolerance range is specified and measured at the 7 station marks so as long as you cross those 7 locations within tolerance, your curve will measure just fine. For CAD drafters that draw the rocker on a computer, it can be frustrating if they don't understand that the rocker is a hybrid and try to draw it using a single arc spanning from bow to stern.
Because we only have 7 station marks and station dimensions at 3 and 4 are both at zero, that area has been nicknamed "the flat spot". If you did try and make that area perfectly flat, when adding the plywood to the bottom it would not lay flat, instead it would bend to a curve so trying to make a flat spot on purpose would be rather difficult to accomplish.
Really doesn't matter what the hull shape is, the concept of our class is that we all use the same hull shape and then modify the other parts to make them go as fast as we can.


In early 2010, we discovered a few people were intentionally modifying the rocker shape beyond our tolerance range.
Each year thousands of yachtsmen cross the Atlantic Ocean, but only few of their voyages set records. The best way I can think of to introduce this story is to read from what’s printed on the back of the boat in three languages. Two of the engineers are Dylan Rodriguez, a 21-year-old senior at Worcester Polytechnic Institute in Massachusetts and Max Kramers, a 26-year-old recent graduate from the University of Rhode Island. December 24, 2013 - Italian driving sensation Alex Carella for the third straight season came from behind climbing the ladder of success once again to win the UIM F1 H2O World Championship in 2013.
The seven month journey began in early June, in Brasilia, at the series first ever event on the South American continent, with Finnish two-time World Champion Sami Selio of the Mad-Croc Baba Racing Team stealing the spotlight winning from pole position with the Qatar Team duo reaching the podium for the first of three times during the year with Torrente finishing ahead of Carella in two of the three opportunities. In mid-summer in late July the tour was off to historic Kyiv for the Grand Prix of Ukraine and this time the story was all about French driver Philippe Chiappe of the CTIC China Team who captured his first victory in his 11 year-career making it a very popular victory throughout the paddock for the likeable driver from Rouen. As the series headed to the Far East for the fall season stopover in the Southern city of Liuzhou at the Grand Prix of China, it was once again time for the Italian to exert himself. His team member Torrente, who was glued right behind Alex the first half of the race, had disaster strike when a brief mechanical problem moved him down to sixth while Sami Selio came home second and Chiappe finished in a close third. It was off to Doha and the 10th Grand Prix of Qatar with Alex nailing down pole position just ahead of his teammate Torrente.
With just two races to be run in the United Arab Emirates, the lead in the championship had changed for the fourth straight race in a row. Meanwhile, Sami Selio got his new boat working to perfection grabbing pole position while trying to forget his own bad luck suffered during a start line accident he had suffered in Doha a week before destroying his number one race boat.
In one of the closest finishing scenario's in the 30 years of racing on the UIM F1 H2O World Championship tour, four drivers were still in the hunt in their chase for glory chasing the title.
When the final checkered flag fell to end the 2013 season, it was Alex Carella setting the stage with a perfect run. There will be once again be many challengers from around the globe looking to claim his thrown in 2014. There are dozens of design and setup factors that influence the performance of powerboat hulls, and most of these features also influence each other.
Deadrise is the measurement of the angle between the bottom of a boat (keel) and its widest beam of the planing surface. The deadrise angle of a Vee hull’s lifting surfaces can have a big influence on the performance of the boat. A flat-bottomed boat rises onto a plane quickly and provides a comfortable, stable ride in calm water - but it can pound heavily in rough water.
Deadrise angles are not always constant along the length of the hull; they often vary progressively from bow to stern. The amount of deadrise designed into a hull is typically driven by the intended use of the boat. Deep Deadrise - Hulls with a steep deadrise angle can slice through the waves, providing a smoother ride. Deep Deadrise Hull With Chines - The addition of chines (spray rails or lifting strakes) to a deep Vee hull can provide some of the advantages of a deeper V, while reducing some of the disadvantages. Variable Deadrise Hull - In a variable deadrise hull, the center section (near the keel) is made with a deep Vee deadrise angle, then the angle is shallower in the next sections outboard, and shallower still out at the edges (chine). Warped Plane Vee – This concept is another very common design compromise that has the best advantages of all deadrise variations. Vee with Pad – Performance Vee hulls sometimes employ a centre located flat pad design for higher lift. Next month's issue of TBPNews will look at how we can design the optimum deadrise for the desired hull application. This is the ONLY software specifically for design, performance analysis and setup of tunnel hulls and performance Vee hulls!

A reverse stern design places the greatest length at the water line, giving this design an increased turn of speed. Where can I find transmission efficiency of chain drive, V-belt, bevel gear, planetary gear, gear belt. In a water only use, this is a bit better than the ?soft curtain? systems, if only in directional stability.
The smaller the contact area the higher efficiency, but this also depends on power, and size requirements. Like airplane design, you pick a configuration for other reasons, and make it as efficient as possible. Planning boats, even fast boats like destroyers, cut away the rear hull to reduce surface friction to a minimum. Even Li-Pos are reasonable batteries provided you follow strict battery charging regiment, cell voltage balancing and fire bag LiFePO4 are considered stable and thus command higher price among Chinese batteries. Siemens and Sanyo still manufacture highest efficiency PV panels, but top Chinese PV panel manufacturers' quality is on par with Siemens and Sanyo. But when I have other family aboard (wife, daughter, grandkids) for a week or more then we would absolutely need all that space especially in Inner Passage or during Pacific crossing.
Far less ?turnover? (heeling motion) and very fast down wind and off the wind, and easy to handle. Just because of better boat handling and safety in bar crossing and square swell conditions we have in West coast.
Better fuel economy, easier availability worldwide, can burn most oil too, explosion safety, longer engine life, etc. This way it is very stable and most safety in all sea conditions, yet modified Seabright hull helps pounding and assist lift for semi-displacement speed I am seeking. I added cruiser since original poster wanted something he can cruise with his wife in protected water.
I can not buy the assumption that minimalistic cutting board and bucket next to a dining table is a live aboard suitable for couple or a family. I know this is relative but I would say something Alaskan homesteader can live in reasonable comfort if moored in their property. It doesn't need to have a washing machine and an air-conditioning, but a microwave oven, a refrigerator, a bathroom with a shower and a desalinator is needed.
Lets set total budget at launch off to $250k, so average Westerner can sell their house and afford this boat. Our racing competition is largely about the skill of the skipper, but also we have the freedom to engineer parts to make our boats go faster. To resolve this issue we now measure hulls for racing (more info) to confirm participating hulls are class legal so there is no question as to whether anyone is cheating and to preserve the integrity of our racing class & the duckers who participate in serious competitions. It says: “Hello I’m Scout, a fully autonomous boat attempting to cross the Atlantic Ocean from Tiverton, Rhode Island, to Sanlucar de Barrameda, Spain.
The 27 year-old from Piacenza led a strong Qatar Team for a resounding one-two finish in the drivers championship out-dueling his American teammate Shaun Torrente by just six points in the end 80 to 74. It looked it would finish that way in the race as well, until, with just three laps from the end, Alex's engine gave out handing his friend Shaun the victory. Bad luck once again visit the Florida driver as Torrente failed to get a lap in the final Q3 qualifying session needing an engine change and moving him back to the 11th starting position for the race. Sami, despite this, dominated the day reasserting himself to the top of drivers championship with a win in Abu Dhabi for his 12th career victory tying Francesco Cantando of the Singha F1 Team as the winningest most active driver on the tour.
He never once made a wrong during the event leading from start to finish for all 38 laps and earning his eighth career victory and adding another World Championship to his resume in just 25 career starts. A hull with a zero degree deadrise has a flat bottom – a deep Vee hull might have a deadrise of more than 20 degrees. A shallow deadrise will provide the most efficient lift, but deeper deadrise angles will make a much cleaner presentation to the water surface in rougher water conditions. A deeper Vee at the bow can allow the hull to cut through waves more smoothly, while lower deadrise sections aftward can make for more efficient planing. When conditions get really rough, the superior ride of a deep Vee hull can be the fastest or most efficient design of the day. Perhaps more important to some boaters, the deep Vee hull tends to punch right through waves (easier) instead of going over them, so it can be a wet ride in heavy seas (inconvenient). Effectively designed chines provide some flat (lower deadrise) lifting surface, which means more lift compared to the higher deadrise angles.
Flats boats often have very shallow deadrise hulls - not pleasant for choppy water, but great for running in shallow water and getting on plane quickly. A moderate deadrise angle hull will not slice through waves as cleanly as a deep Vee hull, but can be more stable, will not roll as much, is fast and fuel-efficient, does not draw much water. When the boat is on plane, the outside sections with low deadrise are not wetted as the other sections slice through waves. Deadrise varies from higher at the bow, lower at midships and flatter deadrise at the transom.
The super power of the software allows for even more comprehensive analysis, employing engineering techniques that include detailed aerodynamic, hydrodynamic and stability calculation methods that are key to proper Tunnel hull design and accurate performance prediction.


The hull is extremely "V-ed" and requires a very high level of skill from the paddler as well as excellent paddling technique to achieve maximum speed and performance. Having very little hull in the water and being highly rockered make it a very fast boat that turns on demand. Because of its low volume, this boat can be constructed at the lowest possible weight, yet still be stiff and relatively strong. The hull is narrower, allowing less wetted surface area, and the flat bottom gives this design accelerating abilities. Cruise ships are very interested in overall economy, so tend to lead the way, but they are also interested in less draft, very low noise, and independent maneuverability, so these could be overriding factors.
Smaller boats also mess about trying to reduce shaft exposure, eventually getting to vertical drive shafts, OB, stern drives, and sail drives. Personal visits to China indicate the indigenous low speed, heavy, diesels are fantastically reliable, running for years un-loved in a field, usually pumping something. Lead acid has reasonable install price and is still good for ballast, but LiFePO4 is stable and price competitive in long run. Chinese have invested heavily in PV cells, lithium batteries and electric motor technologies. Chinese batteries are cheap because it doesn't follow Western distribution channels to get to us. For washing up, a tiny dollhouse sized stainless sink may be cute, but a wash bucket and rinse bucket set on deck by your feet is much more efficient. Multi hulls don't need swing mounted stove Girls like stable boat, lots of initial stability.
But if it is raining and cold, I rather be in enclosed protected space where water boils faster. The circuit gets too complicated and expensive even if super capacitors are inexpensive IMO.
This will reduce pitch-pollinh for multihulls and yawing the monohull to set up for broaching. The highjacker added environmental factor as an highest priority issue for an affordability.
She wants something that can handle some of our grandkids or other guests for dinner and safely cross oceans without too much chumming. A small air conditioner for a cabin would be nice though Remember cruising speed of 8-12 knots and top speed of 15 knots. Because we all use a common hull shape and our boat is so small, that imposes a natural limit on the overall cost of our boats so our class will always be within the grasp of an amateur garage level competitor. The good news is that most of these factors can be calculated at the design stage, and thus we can design a boat for the intended performance.
A group of young men from Rhode Island are attempting an autonomous transatlantic crossing with a solar-powered boat they built in their spare time. I was built over the course of three years by a group of young optimists after a successful Kickstarter campaign. The Floridian had earned his first career victory on the tour and had now moved into first place in the championship with 55 points.
Shaun Torrente would make it a Qatar Team one-two sweep, pushing Alex early and then realizing he didn't have an answer for the Italian. In many cases, a hull will be designed for a multi-purpose operation with a compromise deadrise angle in the range of 15 degrees. As the hull goes faster, the hull can ride “higher” on the Vee, reducing wetted area for less drag. The boat with pronounced chines will also draw less water, will have greater roll stability, and the chines can deflect spray generated. Such hulls sometimes have a steeper deadrise angle forward, transitioning into the much shallower deadrise swiftly as the hull beam widens out aftward. Of course, the moderate deadrise hull will not go through waves as readily as a deeper Vee design, but also will not broach or heel excessively in turns, and is often a pretty dry ride. The advantage of the variable deadrise design is allowing the boat to plane at lower speeds compared to standard deadrise. This gives a ‘twist’ or warp of the deadrise, and the chine will run downward in profile lengthwise from bow to transom.
Pads are usually part of a Vee hull design as a method of increasing total hydrodynamic lift capability and increasing top speed. XPorpoise is an engineering tool developed by AR that predicts your hull's inherent susceptibility to instabilities that lead to porpoising. It has no concave sections or flat spots and it is very stable; maintaining this stability in rough water and while turning. This hull shape and seating position give this boat its speed, especially in shallow water. Although an older design, it has proved itself superior to some of the newer, more radical designs. The smaller the area, the higher the pressure, the higher the noise, and the higher the power density. Roller chain drive is usually the best, not a coincidence that we see it on bicycles, and human powered aircraft.
I suspect the sail drive should be lower drag at slow speeds, no ?base drag? at the transom like a OB or stern drive. Cheap cells are usually subject to these kind of manufacturing faults, but expensive ones are not necessarily better, merely more expensive.
The catamaran has stable large platform deck and private cabins but difficult to have large standing gathering space and reasonable windage. Regardless of who makes the diesel engine, it should be low RPM, non-turbo, low tech diesel then it is low maintenance and long life. 4 out of top 5 volume PV manufacturers are Chinese, the other is Korean owned company in China. Properly matched battery cells, good battery management circuitry and proper cell balancing will give 1000+ recharge cycles compared to 200+ recharge cycles on best US AGM batteries. 3' chop is fine with small wave piercing but 8-12' swell with 3' chop on top, which is typical for even Northern California water won't work with small wave piercing hull. Monthly operating cost including fuel should be less than $2,000 so minimal fixed income couple can afford to live on it. Sometimes a hull will have a Vee with a higher deadrise at the keel and lower deadrise at the outermost chines.
If the bow of the boat is kept down, such a design can slice through small waves better, but once the waves are big enough the aftward flat sections are going to pound. This concept provides good wave-breaking capabilities of the deep Vee at the bow and lift-efficiency of low deadrise aftward in the region of planing surfaces. A flat pad (zero deadrise) is the most efficient lifting surface and so generates high lift and less drag at higher velocities. A full sectioned bow, high volume and ridge running the entire length of the deck prevent the bow from plunging in big water and give the boat structural stiffness.
Winning the US Wildwater National Championship 1982, the Lieser King still retains US championship status. Toothed belts and V belts are pretty bad, they need a lot of lateral tension to work properly.
Military ships are also interested in efficiency, even if only to go fast, and they use variable pitch propellers for acceleration as well. Hence track record of a manufacturer, or constant personal surveillance (inspection) is necessary to ensure quality.
Some are claim to have up to 90C rating, but I doubt that is a true engineering specification from reputable manufacturer.
Due to the very deep Vee shape however, these hulls have a deeper draft, don’t like non-planing speeds and demonstrate poorer fuel economy at slower speeds. This design won both the 1983, '84 US Wildwater National Championships and the Team Trials. They are usually chosen for cheap, or a visually obvious life, ease of replacement, or on aircraft, a stated, specific, but limited life. The waters I would like to sail would be PNW Inner Passage and South Pacific Islands ICW and Mediterranean doesn't sound bad either. Rare earth magnet required for high quality electric motor are mostly mined from China, and China is restricting exporting strategic rare earth materials and forcing manufacturers to setup shop in China with Chinese manufacturers.
So we are seeking an affordable, environmental, offshore, ocean cruiser live aboard that can be trailered or demounted. The XR-5 is the same hull as the X-5 with a little more rocker for a quicker turning response. I can get low tech 50-100 HP Chinese agricultural diesel engines for small Japanese diesel price.
They seems to be prevalent in most RC hobby website, so I am guessing it may be RC hobby marketing talk where some degradation and occasional battery fire is acceptable.
