    To compete on the level of some of the best plane dinghies going, you'll have to do more then find a .PDF with a few design pointers in it.

    There are literally thousands of skiff designs around the world, some old, many newer, with quite a few plans being free or low cost.

    Each will be designed around a set of compromises the original designer hoped would satisfy the client's desires. Most every designer will have their own, unique perspective on what makes them fast and handy racers. None will be the same, nor will they use the same principles, though they may look and perform very similarly.

    There are several good books available on yacht design. The book store here has all the major ones or you can try you own favorite book seller. Learn as much as you can and pattern your first few design attempts after well known successful boats. Once you get a feel for how and why they work, you can explore other options, possibly improving and creating a new "Laser" for the 21st century. Good Luck . . .

    Paper Jet is close

    There's an excellent article in the Professional Boatbuilder Magazine this month about the Dudley Dix designed skiff he is offering as a kit for builders.

    You can read the article here: http://www.proboat-digital.com/proboat/20071201/ and flip forward to page 26 for the first page on the boat.

    The skiff in question is very close to the specs you mentioned and it may give you some ideas.

    You can also see the boat at the Dix website : http://dixdesign.com/paperjet.htm

    I have been thinking of building a plywood skiff for some time. Here are some links for High performance wooden boats. Look at the Javelin. It is a single trapeze asymmetric skiff. Free plans for plywood composite are on the website. http://www.javelins.org/
    http://www.javelins.org/Technical/buildyourown/buildingIndex.html


    You can also look at the UK Cherub site. It is only 3.7m but there is lots of information about plywood skiffs. Http://sailingsource.com/cherub/test/doku.php/start
    See http://www.geriatric-gigolo.co.uk/ for a plywood cherub example.

    http://www.dinghy-plans.com/stealth.htm - Richard Woods designed single handed skiff. 4.2m Plywood.

    None are the dimensions you are looking for but you might find them interesting

    Thanks a lot for your precious support, now i'll develop my personal design related by rules that i must trace.
    Because i'm constrained by the wood , i think that the better solution to have a light boat is to realize a construction using strip plankig.Are you in agreement?
    Other solution is stick and glue but i have to use more transversal element to give more resistence at the hull and avoid deformation reised by thin multilayer wood panel. I mustn't pass over 80 kg .Generally the other boat have used double form to hide frames, but i've seen that are more weighted down respect the winner that was realized in single form .

    The lightest build you could hope for would be a wood core composite, Lindsay Lord method or a molded hull shell. These will keep you within you weight constraints. The shapes will provide the performance envelope, but considering the very basic nature of your questions, you have quite a bit of information to absorb, before a successful design can be contemplated.

    I'm agree around that i've to absorb a bit of information but i 'm well-intentioned to make a good project.....i hope..
    Thanks a lot for your support.

    Come on, Satan, use Google, type in Swift solo and a whole bunch of resources come alive for you that spell it all out.

    Here: http://www.google.com/search?hl=en&sa=X&oi=spell&resnum=0&ct=result&cd=1&q=swift solo&spell=1

    I'm kinda puzzled that a guy who wants to design and build a skiff along the lines of one of these very high performance rides is not willing to do more of the work on his own. A boat like the Swift is not a beginner's ride and it more or less implies that you have your act together.

    I don't want to be rude, but.... Do some homework on your own, please.

    Having driven a Swift Solo, I can tell you it's not a beginners boat. I was surprised how easily I got a handle on her, though she dumped me in the water a few times to tenderize my pride a bit. If you want to go faster then any another dinghy on the puddle your sailing, try the Swift Solo, be prepared to get soaked, then scared, from ear to ear, if you know what I mean.

    I got a similar impression about he original poster, Chris. Even if his designing focus has been motor vessels as he suggested, the hydro skills would still apply, particularly in a fast plane dinghy. Personally, I think he's looking for a free set of plans for something quick. If that's the case, I suggest "Splinter" maybe with another 10% more sail area just to keep things honest.

    Could someone educate me, who or what is "Splinter"? I did a search but as you can imagine "splinter" comes up with all kind of stuff?
