Bonjour, avant tout, je ne suis pas architecte naval, je suis maître ébéniste et maître menuisier français de formation et d'expérience...

      Je voue une véritable passion pour la construction au sens large, j'aime concevoir, étudier la faisabilité puis réaliser l'ouvrage en atelier... 

      Ayant été chef d'entreprise de ma société de fabrication de meuble, j'ai été comme perverti par l'obligation de rentabilité propre a toute compagnie.... Me reste de cette expérience d'excellents souvenirs mais un refus de m'endormir sur des acquis....

     C'est dans cet esprit que je me suis lancé dans l'apprentissage de l'architecture navale, Ce que j'y ai découvert, des techniques passionnantes et un constat incroyable d'absence de communication entre les différents métiers, en effet l'apprentissage de la construction navale m'a ouvert des horizons passionnants, techniques originales, matériaux différents de ce que j'utilisais, et pourtant la maitrise de ces techniques m'aurait bien des fois dépanné dans le métier du meuble oü il est parfois bien difficile de maitriser les variations dimensionnelles liées aux variations hygrométriques... Même si jamais on n'empêchera un matériau de travailler, la construction navale a de la bouteille dans les solicitations et efforts exceptionnels... La maitrise des ouvrages courbes, incontournable de la construction navale, nous oblige a pousser aux extremes limites notre maitrise de la géométrie descriptive...

     Fort de ce constat, apres avoir ingéré tant bien que mal les bases de l'architecture navale et construit mon premier bateau, je me suis dit que s'il y avait une absence de communication entre menuiserie navale et menuiserie du batiment, il devait en être de même dans l'autre sens... J'ai donc abordé les produits suivants comme un menuisier/ébéniste, ai ressorti du fond des tiroirs les assemblages traditionnels et ai joué avec les outils modernes, un logiciel de DAO et une machine laser numérique...

      Mon objectif était égoiste, apprendre, me surprendre moi-même, les tests ont été au niveau de mes attentes, des ouvrages excessivement précis a la symétrie parfaite, et surtout une vitesse de réalisation époustouflante...

      Je tiens donc a remercier tous les gars incroyables qui ont travaillé sur des software tout aussi déments qu'eux, sur différents add-on, modules externes et plug in ultra pointus qui m'ont permis de mener a bien mes projets le plus simplement du monde...

      Fort de leur générosité, c'est á mon tour de donner, en espérant participer a la démocratisation de la construction, juste retour... :)

      Hello, in first hand, I am not a naval architect, I am french master cabinetmaker and master carpenter by diploma and experience ...
      I have a real passion for building how wide it can be, I love design, conception study and then complete the project by building myself...
      Having been in business like director of my own furniture's company, I was like perverted by the obligation of rentability compulsory to each company .... At end, i have great memories of this experience, but a refusal to fall asleep on acquired ....
     It is in this spirit that I started learning in naval architecture, What I discovered : exciting techniques and incredible discover of lack of communication between the various crafts, in fact learning shipbuilding opened exciting horizons, original technology, different materials that I used , yet the mastery of these techniques would help me many times in my precedent business where it is sometimes very difficult to manage with dimensional changes due to hygrometry... Even if we will never be able to  prevent the material work, shipbuilding offers heavy experience in high solicitations and outstanding efforts... The mastery of curvable buildings, imperative in shipbuilding, pushes us to the extreme limits of descriptive geometry ...
     With this in mind, after having ingested somehow the basics of naval architecture and built my first boat, I thought that if there was a lack of communication between ship carpentry and buildings carpentry, it should be the same in the other direction... So I studied conception of following products like a carpenter/cabinetmaker, took out of drawers the traditional assemblies and played with modern tools,  CAD softwares and numerical laser machine...
      My goal was selfish, learn, surprise myself, the tests were as high as my expectations, excessively acurate works with perfect symmetry and especially a crazy speed of realization...
      So I want to thank all the amazing guys who worked on softwares as amazing as themselves, on various add-ons, plug-ins and ultra sharp outlets that allowed me to conduct my projects with big facility...
      Feeling happy because their generosity, it is my turn to give, hoping to participate in the democratization of construction, just coming back ... :)

Delphi 15 is a kit concepted to have perfect symmetry and fast building limiting at its maximum the building's mistakes and square errors, the delphi is 4m50 long with cathedral hull to have efficient stability, the delphi is really original because the outboard motor is inside the hull and not in back of the transom, it's covered by an insulated cover offering less noise and nice comfort in navigation, the rotation of the hull is obtained by rear rudder like inboard motors.... its light weight offers nice speed increase with a simple 40 hp, the beam of the hull 1m60 and the cathedral hull form insures big stability. This small boat offers comfortable navigation up to 4 people.... the banana form of the hull accelerates the way to the planning navigation, this planning access is increased by the form of the top rudder which contributes to press the boat down to planning with 6 degrees down angle, after planning the angle of this rudder changes to 8 degrees top angle like a plane rudder to stabilize and fix the planning angle of the hull. the cathedral hull allows a performant hydrodynamic in water. this really light boat allows lake and costal navigation, can go further in sea with experimented captain. the average in fuel with max crew at 20 knots should turn (suzuki dt40wr ref) around 8,8 liters/hour.... Delphi 15 is ideal for leisure and towing nautic ski and wakeboard with its integrated traction fixation in the back rudder...

This system is really fast building and low mistake, can be done by people building their first boat.... 

You can venture offshore safely with Alti 22’, its proven Vee-hull design is unsinkable and very maneuverable. 
Carrying up to 9 persons in a large open space area, you can ride at 25-30 knots with only a 70 Hp engine! 
For a day at sea cruising or game fishing without spending too much on fuel, you can’t beat Alti 22’. 
He can also be used as a towing boat for water-skiing, wake boarding, banana boat and even paragliding!

 

optimist kit, grade marine plywood, epoxy and fiberglass, fast building and economic cost, don't need mold, building hull in two days before stratification...

 

Building process design, step by step, you can print this panel on big size and build your boat step by step...

Download on dropbox the 5 pannels of 6 mm plywood allready organised with all optimist's units ready for laser cutting...

You will have to keep it in adobe illustrator format or export to your own format depending of your machine's software.

Please download the pdf file, it is all phases step by step you have to do, you have to respect the order and every time glue the units together using 6 mm threaded rods, wings nuts and washers : the best way is to buy long one and cut them before, i already calculated the quantity and length to win time : 42 of 80 mm, 27 of 60 mm, 2 of 120 mm, 74 of 40 mm …the glue is bi-component epoxy, usually the proportion to mix resin and hardener are one for one volume, or depending of the weight (100 g epoxy resin for 80 g hardener, but you have to check before the glue specifications, it can change regarding the brand, it is very important to respect the proportions), don’t hesitate to ask questions on this if needed…With threaded rods, you can press, clean and do the next step without waiting the glue to dry…Until step 17, please count in order on pdf building plan, you glue every time, but when you do step 18, you just fix all together without any more glue, you just press and progress…You will glue again for sections of the sides on step 22, you glue all plywoods and press in one time, you glue again for 25 and 26, and here you check the whole boat if all sections all together look great, if it is, you only glue all connections of all parts with epoxy resin and charge like micro ball, you will do filets every where… you wait until the days after for glue to be dried, and you can cut all the plywood crossing the hull you used to press, you don’t need more… At this point, work on outside stratification by fiberglass… i stop now, you have good work until here…Don’t hesitate to ask more questions on Forum if needed…

Click on the left image to download the 3d Sketchup file of the optimist, play with all units and understand how they work together, all axes designed are 6 mm bolts... they allow to press during glue works without waiting glue is dry, you will win a lot of time and will never have to wait for next step...
