Location: Lake Michigan I don't claim to be an expert, but for speed, little to no rocker is good. A race boat would have to be longer (the longer the better) and a bit wider (but not much wider).

Location: Marshfield massachusetts usa Terhohalme, Very interesting piece of work, I'd be interested to find out more about your boat.
Location: Trondheim, NORWAY I think you could try minimum wetted surface, long waterline and optimize the Cp for your speed. Location: Marshfield massachusetts usa Safewalrus, That Flashboat, VERY interesting can you point me to plans?
Length must be an important part of the speed equation,a long narrow boat will always be faster than a short wide one.
1 ) A fast rowboat will probably be as long as possible and because of its length will be able to have as narrower beam as permitted by the required displacement.
Bow steering ,yes like you guys I am concerned about bows digging in and directing the issue. There must be a point where the trade off between wave making and wetted surface is at an optimum..
When making potentially dangerous or financial decisions, always employ and consult appropriate professionals.
The idea of using solar and human power to drive vehicles is nothing new but each new design that applies these principles is at least a step in the right direction – away from fossil fuels. Perhaps the best part about these designs is that they push the boundaries of current thinking and appropriate green technologies for seemingly everyday uses. I am not sure how practical this designs are, I mean – is the solar power is ebough to run the boat? Don't forget you would charge it up before you went out as well so you could get most of your traveling done without sun or pedals.

Ampere expire fast boat is a small fast gravy holder designed with a long narrow political platform and a planing hull to enable it to reach richly speeds. De Corvette C2 werd ontworpen door designer Larry Shinoda onder leiding van Bill Mitchell die ook de Ford Mustang heeft ontworpen. De carrosserie was, net als bij de C1, gemaakt van glasvezel om gewicht te besparen maar ook om de designers meer vrijheid te geven. Een aantal designkenmerken zoals de vier ronde achterlichten waren overgebleven van de C1 maar verder was de auto totaal anders.
Naast de productieversie van de C2 heeft het hoofd van het technische team, Zora Arkus-Duntov, in het geheim een raceversie ontwikkeld. Er zijn echter wel een aantal races gereden met deze auto’s al was de Grand Sport niet genoeg doorontwikkeld om grote successen te behalen.
Zeg, weet iemand waarom men in godsnaam minder pk’s zou opgeven dan er daadwerkelijk inzitten. Een van de mooiste Corvette’s, zoniet de mooiste… dit was lange tijd mijn nummer 1 droomwagen! Het geluid van de 427 is 1 van de mooiere geluiden uit de autoindustrie die ik in de afgelopen 5 jaar tegen ben gekomen. Inderdaad een van de meest mooie auto’s ooit en zeker de krachtigste van zijn generatie volgens mij. Ze kregen het echter niet goed genoeg voor elkaar… Het kleurenschema met unieke glanseffecten was niet na te maken en toen hebben de spuiters doodleuk de opgezette haai overgespoten om toch een perfecte match te krijgen. Bij de presentatie werd de overgespoten haai naast de gespoten auto gehouden en iedereen was tevreden. De crashboxen voor en achter bepalen de minimale lengte en de voorruit is fixed, dus daarmee zijn de proporties wel zo’n beetje bepaald. Een Z06 is van alle Vette’s nog het meest geschikt om er een C2 Stingray look-a-like van te maken.
Folding Bike Concept by Kilo Estudio Folding bike design evolves every single day in order to provide us with best transportation, easier and more efficient in big cities. I agree with it looking an awful lot like Wally, plus the bow of that ship is awfully dangerous in case it hits a wave it would probably flip itself. But the flat-bottom skiffs tend to porpoise and pound, and I might occasionally tow a skier or want to cruise sort of fast, while a 40' deadrise is a bit much for me. So, I have been looking for shoal draft, chop handling, and ability to cruise comfortably on plane.
Then I started drawing and -surprise- same up with a 20ft skiff (is there a prize for the billionth design?).


I realize it might not perform better than other S+G designs (at best) but to me the look is better, with a couple extra panels.
Location: maine Regardless of what she'll do motoring, I saw nothing in the lines to prevent sailing rather fast with the right rig.
Location: Pontevedra, Spain You'll have to keep that forefoot out of the water when planning, or it may induce directional instability, in my opinion. I have only crude guesses about trim under power at this stage, but with an outboard, it should not be hard to have the bow trim up.
Now all I have to do is turn the aft stations to true monohedron and I would have something I could buy on any street corner-the homogenized skiff! Location: Sydney I think your second design looks much better - no need for that pointed forefoot in the first one, and that wedge did look like the drag would outweight the benefits.

Location: Kingston, UK Just to clarify, I'm referring to the process of creating flat templates for the planks from the full scale line drawings. Sorry if these are stupid questions but I'm new to boatbuilding and no-one seems to be able to tell me exactly how the actual build process works. Location: Oriental, NC Gus, Here is a thread on another forum of a recent lapstrake build of mine.
Once I have finished designing a hull in the software, I use the feature that creates a cutting pattern for each panel. Every time I've designed a boat in my software and used its patterns like this, the results have been practically perfect. To lap the strakes I would simply cut them an inch or two wider than the patterns illustrate, depending upon how much I want them to overlap. I did not know if you had actually done this to completion of a clinker boat from a computer program before. If I try lapping the panels I will probably still use pre-cut plywood strakes and epoxy filler instead of bevels at the joints. Or I can put more time and effort into computer modeling and come up with precise patterns specifically for lapped strake construction. One of my concepts for the construction of a light weight lapped strake boat is to use thin plywood strakes, perhaps only 4mm or 5mm. John Welsford designs boats with stringers installed first on bulkheads and frames, then his strakes are 'cut to fit' on top of the stringers, each one beveled to the next, with the stringers visible inside the hull.
I would set up the bulkheads and frames on a strongback or on the keel if the boat has one, then alternate the installation of strakes and stringers -- install a strake first, then a stringer, then another strake, then another stringer, etc. In this type of construction the hull should be as self-fairing as in a strip planked boat. Granted this is only a concept at the moment, but I can see no reason why it won't work, although I'm sure I will discover some issues the first time I try it. If a boat has no need for frames for strength, I see no reason to ever include them in its construction. Boats like Welsford's use few strakes and tend to show a thick lap at the turn of the bilge caused by the small radius there and thinner laps elsewhere. These words may well be attributed to the yacht Mariette, year of construction of which dates back to 1915.

One could envision a small fleet of these replacing rent-a-boats at various tourist destinations around the world.
The solar and pedal option just extends the range to as far as your feet and the sun will let you!

De C2 was als coupe leverbaar met een kenmerkende gesplitte achterruit die eindigde in een puntige achterkant en twee neppe luchtinlaten op de motorkap. Deze Grand Sport was gebaseerd op het prototype van de C2 en moest de concurrentie aangaan met de Shelby Cobra van Ford. Dat ontwerp die lijn die achterruit die sidepipes die tankdop die uitlaten zoo mooi verwerkt in de carosserie die acceleratie enz enz…kwiijjlll! The same is not just confined to the cars or bikes, but also to other means of transport like boats. Maybe needs a touch more flare -tough issue for me ( - I'm from Va but went to school in NC ).
So I was thinking originally if warped it might run flat enough to be good if I stay out of nastier waves. It takes more time and effort to go for this much detail in the software because each lap must be modeled individually, but it can be done.
Yachts are equipped with modern equipment, and their degree of comfort will satisfy even very demanding person.


The second yacht was born in the Italian town of La Spezia and technical characteristics to the yachts in their class now issued much later. During the Second World War, carrying the watch off the coast of the United States, hunting down German submarines, and I must say much has succeeded in doing so. Looks like a very fine entry and straight run with a lot of flare in the mid sections to get enough spread for oars on gunnels ( a requirement in our class). Still, you get to toss out the pricey gas costs associated with most water cruisers and relax in the sun when the weather is nice and pedal your way to shore when it isn’t. Sufficient power storage is a must so that pedaling is kept to a minimum and done only in emergencies.

Toch was dat niet slecht want de C2 met de bijnaam Stingray staat in de top 10 van beste sportwagens van de jaren ’60. Onderhuids had de C2 onafhankelijke achterwielophanging wat behoorlijk vernieuwend was begin jaren ’60.
Duntov wilde 125 homologatiemodellen bouwen zodat de auto mee mocht doen aan de Grand Touring races. This new concept boat by industrial designer Andrew Bedov, promises to be an eye catcher and designed with traffic stopping looks. I like the near-plumb stem, so kept that in spite of the lightness of the boat, since I'm not looking to go in big water. Hoping it might run 20-25kts with a 70hp OB, cut small steep chop easily off plane, and if lucky run comfortably at 15 or so. My ideas come from eight years of racing and constant observation of our own two boat as well as the boats we race against. Weather prediction for our 4 mile race on Saturday is for temps to be 53 degrees F and winds to be 10-15 kts.

Tad Roberts,a designer in Washington State, a forum contributor, was kind enough to send me a set of limes showing his concept of a fast row boat, and they gave me a lot to think about. Er zijn dan ook maar vijf Grand Sports gebouwd die allemaal in privecollecties terecht zijn gekomen. I would appreciate a general discussion of design factors from people who are more knowledgeable than myself.

Whatever she does, it's a fast boat (good crew too ) Does semi-planing happen, is it good or bad?
In 1967 had eigenlijk de opvolger klaar moeten staan maar doordat deze vertraagd was, bleef de C2 nog een jaartje langer in productie. Current plans are to put some rocker in forward to reduce bow steer and reduce wetted surface.
