    The ISO 12215-5: 2019 standard has entered into force last June and introduces various changes with respect to the 2008 version, making it more complicated, if this is possible, for its use by the normal user. We are updating our "SCT" application that helps calculate the scantlings of small boats, according to that standard.
    An interesting change is that its scope has been extended to:
    • recreational craft, including reacreational charter vessels.
    • small commercial craft and workboats
    This makes the standard very useful not only for pleasure boat manufacturers but also for small shipyards of small commercial vessels.
    If you are interested in our software and/or would like more information, contact us directly.

    There is info that 2008/2014 version of standard will still be used for 2 years, any official references?

    I would not rush to use 2019 version, likely it is full of bugs.

    Thanks for the news, Alik. I will investigate about it.
    The June 2019 version says "Supersedes EN ISO 12215-5: 2018"
    I will try to adapt my software to the June 2019 version, hoping that there are not too many corrections in the final version, if any.

    Thanks again, Alik. I understand, then, that the new version can already be used although, for two years, the two versions may "live" in parallel.
    I think the sooner I adapt my software to the 2019 version, the better. I will keep you informed of the progress.

    ISO 12215-5: 2019 is disappointing. It has errors, of course, but that is not the most negative. They have changed formulas, criteria, definitions, and all that, I suppose, with the intention of making it more complicated for the user. If that has not been the intention then I do not understand anything. I have been working with the standard for a month and I am not yet able to establish a procedure, a suitable sequence for calculations. I have reached the determination of design pressures but from there, the next step, which should be to obtain the design sigma, I am unable to continue.
    If someone thinks they could help, their collaboration would be very welcome. Thank you all.

    You can ask this guy, he seems to have developed it: https://www.researchgate.net/public..._12215-5_for_Hull_Construction_and_Scantlings
    Unfortunately they don't want to listen practicing designers, those Uni teachers. I mentioned some faults at conference last year, but seems nothing has been corrected...
