    Stability & Evaluation with ISO 12217

    Link to the course: Stability & Evaluation with ISO 12217 https://navalapp.com/courses/stability-evaluation-with-iso-12217/

    (Check other Navalapp courses here).

    What will you learn?

    After completing the course, you will deeply understand ship stability and how to apply this knowledge to use the ISO 12217 Standard, “Small craft — Stability and buoyancy assessment and categorization,” Part 2, “Sailing boats of hull length greater than or equal to 6 m.”

    The course is structured into three different sections:

    • Stability Theory
    • ISO 12217 (focus on Part 2)
    • Example
    – Stability Theory

    This section focuses on familiarizing you with the theoretical aspects of stability.

    With that aim in mind, the instructor explains here concepts such as hydrostatics, initial stability, large angle stability, factors influencing stability, and dynamic stability, all of them necessary to master ship stability.

    The knowledge acquired in this section will allow you to tackle with confidence sections 2 and 3 of the course.

    – ISO 12217

    In part two, the instructor explains the ISO 12217 standard looking at the different requirements for each of the design categories established for boats.

    – Example

    The course ends with an example: a complete evaluation of an “A” design category sailing yacht, where the instructor will guide you throughout the full assessment.

    Note: when discussing ISO 12217, this course focuses mainly on Part 2, i.e., “Sailing boats of hull length greater than or equal to 6 m.”

    ISO 12217. Small craft — Stability and buoyancy assessment and categorization

    The ISO 12217 standard defines methods for assessing the stability and buoyancy of boats. It also specifies four design categories (A, B, C, or D) which align with those defined in the Recreational Craft Directive of the European Union, 2013/53/EU. After adequately evaluating the stability, buoyancy, overall design, and maximum load, a boat is assigned to one of these design categories.

    The standard applies to vessels with a hull length less than 24 meters and has three different parts:

    • Part 1: Non-sailing boats of hull length greater than or equal to 6m.
    • Part 2: Sailing boats of hull length greater than or equal to 6 m.
    • Part 3: Boats of hull length less than 6 m.
    When discussing ISO 12217, this course focuses mainly on Part 2,i.e., “Sailing boats of hull length greater than or equal to 6 m.”

    Course organization

    The course is video-based and on-demand and can be followed at the student’s own pace.

    It contains videos, quizzes, and downloadable documents. Students who complete the course will obtain a Certificate.

    Course students will also have access to the virtual private classroom, where they can interact with the instructor and fellow students.

    Resources:

    • Video lessons.
    • Lesson materials.
    • Quizzes.
    • Final Assignment.
    • Course Evaluation Survey
    • Virtual Private Classroom
    • Course Certificate

    Maxsurf software license

    In some lessons, the instructors use marine vessel design and analysis software Maxsurf. Students do not need this software to follow the course or to obtain the course certificate.

    However, for those interested, we offer Navalapp PRO members a FREE Maxsurf Ultimate Academic Version License. You can read more about this offer here.
