    There is a need for more than just reading rules - type of courses, to give students a better understanding what is behind the rules.
    Im sure this will fill the "gap" between just reading the rules - and a 3/4 year Uni course...for those that need a 'bit more' info.

    Good luck with the course.

    Hi,

    Some words to say that we did it! We have launched the two new courses we have been lately working on:

    - Composite Materials 1:
    https://navalapp.com/courses/composite-materials-1/

    - Structural Design & Scantling with ISO 12215:
    https://navalapp.com/courses/structural-design-and-scantling-with-iso-12215/

    The courses are video-based and on-demand and can be followed at your own pace.

    They contain videos, quizzes, and downloadable documents and give access to the course’s classroom, a virtual place to interact with the instructors and fellow students.

    Students completing the courses will obtain the Course Certificate.

    By the way, we are currently preparing new courses. We will disclose more very soon!

    Be careful not to confuse the structure of a hull with that of its mold. ISO standards for small boats do not say anything in relation to the molds.

    I have some excellent news I wanted to shared with you!

    After a thorough evaluation, the Royal Institution of Naval Architects (RINA) has found that Navalapp’s course Structural Design & Scantling with ISO 12215 meets the requirements for Continuing Professional Development (CPD) of the Institution. Therefore, RINA has considered that the course warrants their recognition and has issued a Certificate of Endorsement.

    During the evaluation, RINA studied different aspects of the course, such as learning aims, content and structure, whether the information is up-to-date and is factually correct, students’ evaluations of the course, the supporting information and materials, the instructor’s expertise, the method by which the students are evaluated, and Navalapp’s organization standards.

    The course:
    Structural Design & Scantling with ISO 12215 https://navalapp.com/courses/structural-design-and-scantling-with-iso-12215/

    If you are interested in Structural Design & Scantling determination following the ISO Standard 12215, join more than a hundred fellow Students from more than 40 countries worldwide (... and increasing)!

    Enjoy!

    Thank you very much @Ad Hoc . Yes, it is indeed. We are very excited about it.

    RINA has also recently issued Certificates of Endorsement for the courses "Composite Materials 1" and "Yacht 3D Modeling with Rhino - Level 2." These three courses join the list of the Navalapp courses endorsed by RINA. And there are more to come!

    I have to express my strongest rejection of the facts that I narrate below. I just received the following request for help:
    Need Help.jpg
    I see that my texts have been blatantly copied but, in some cases, introducing beginner's errors:
    - distances are not measured from the after perpendicular but from the aft end of the water line.
    - design stresses have nothing to do with design pressures. They are totally independent.
    - The notation "800ROV-450M" is my invention. It would not have been a serious problem to waste a couple of seconds creating Navalapp's own notation.
    Apart from all that, it amazes me that a student in that course has to turn to me because, apparently, his tutors do not pay him due attention. The truth is that he amazes me, but it doesn't surprise me. A course is what its tutors are, not what a nice advertisement may make you believe.
    I think it is embarrassing to see that these situations can occur and that there is no way to avoid them. What do you think?. What would RINA say about all this?

    Hi @TANSL ,

    Not for writing once again false statements, they become true.

    In December 2021, you contacted me proposing to prepare a course for Navalapp on Scantling based on ISO 12215. In January 2022, you joined two other Navalapp instructors to develop that course.

    You worked weekly in this Navalapp course from January 2022 to September 2022 as a team member with the other two instructors and me. The course was launched at Navalapp in June 2022. We closed the course for new students in September 2022, and we discontinued it in March 2023. In August 2023, we launched a completely new course: Structural Design & Scantling with ISO 12215.

    During the nine months, you worked as a team member together with the other two instructors and me, we met weekly (we had a weekly meeting every Friday at 9 am) to prepare and define the course, its structure, and its content, answer the student questions, distribute tasks, and define and review the materials created, including course materials, drawings, images, etc.

    For that course, one of the other two instructors designed the whole boat. A boat, by the way, you have used in your posts and publications, without our permission, to promote your activities.

    Also, during that time, the other two instructors worked on improving and developing scantling calculations that were not available in your software. I am thinking of the calculations related to the keel, where, based on your own words, "you hit a wall" and didn't know how to approach the subject. To my knowledge, you have never honored or credited that work from which you are freely benefiting.

    Once the course was launched, we started to have issues with your software, and at the same time, your professionalism and behavior changed drastically. At one moment, you asked me to push the other two instructors out of the course because you wanted to be the only one on board, but I didn't accept. Then you decided to quit, which I accept. The other two instructors and I then decided to close the course, which we did in September 2022 (only two months after launching it), and start the preparation of a new one.

    When you left, you took the 180 pages of documentation (pdf) we created for the course to try to make a benefit out of it (and you still try). At the same time, you started to try to discredit Navalapp and the other two instructors on different social media. You even used our own publications and posts to try to discredit us and, at the same time, promote your business activities. Regarding the materials you took, we emailed you to remind you that you cannot use the same material we created for the original Navalapp course. You had to create your own original work.

    @TANSL , I understand things didn't turn out the way you wanted. I know how frustrating that might be. However, the gravity and aggressiveness of your comments, the already very, very long period during which you are targeting us, the randomness in the argumentation, and the willingness to discredit our work and that of the other instructors show that you may still be sitting in some personal pain that, for some reason, you cannot get out of it. And I feel very sorry for that.

    From my side, I wish you well, healing from the situation you might be in, that you can move on, and success in all your endeavors. I really mean it.

    @Pablo Sopelana, assuming that everything you say is true, which is a lot to assume, nothing you say answers the main question, why are beginner's errors introduced into the texts of that course that (according to what you yourself imply? ) has nothing to do with the one I created?
    I innocently ask myself, how can someone, who has never carried out the complete calculation of any ship, try to teach scantlings? Because you should know that scantling is something more than calculating a resistant modulus or a thickness. But for that you would have to read my course (which apparently is not even similar to Navalapp's)
    I also wish you the best but, as you very well know, I am committed to denouncing the impostures.

    Question on ISO12215-5:2019 - looking for procedure to define pressures for a panel which is partly a bottom, ans partly side.
    In older versions there was some... new is not?

    Yes, there is talk about it, but let's see what Pablo has to say about it. Navalapp knows the subject and gives courses on it.

    Seems in the new standard they just define the load by the 'center point'...

    Hi @Alik ,

    Yes, an updated version of the 12215-5 has been published.

    My understanding is that the procedure for calculating the scantlings of panels and stiffeners spreading different areas hasn't changed, but some of the variables going into it will have (e.g., pressure or requirements). Pages v and vi of the new version summarize the changes made.

    You can contact Javi or Pablo in Navalapp. They are the experts in the subject. They will be happy to assist. You can also try to contact Jean-Baptiste Souppez, who sits on Navalapp's Advisory Board. He represents the interests of the British Marine Industry in the development of international structural regulations (ISO 12215) and has been involved in the development of the standard, including the last 12215-5 release.

    By the way, a completely unrelated question: do you have experience designing centre console boats? There might be a new project coming our way ...
