Welcome to this introductory course to Sailing Yacht Design!

This course is structured into different modules that will cover the main aspects of the design process. These include the theoretical fundamentals of sailing, yacht modeling, hull and appendage resistance, sail forces calculation, and stability topics.

During the course, the instructors will guide you through the first design cycle of a new sailing yacht, showing their methodology, the software they use, and explaining the design decisions and trade-offs made.

The instructors will also carry out performance calculations for the newly created design using software tools commonly used by professional yacht designers.

What will you learn?

The course starts by discussing the most important qualities of the hull and how they depend on each other.

The first characteristics assessed are those linked to velocity. These characteristics make a boat more or less capable of attaining its hull speed and maximum speed possible with the available wind.

Then, the course moves into the aspects linked to stability and discusses form and weight stability and the boat’s righting curve (GZ curve).

After stability, the instructors explain the concept of added resistance in waves and how it relates to the hull shape and the distribution of weights.

Next, the boat’s capacity to sail close-hauled, which depends mainly on the relation between the sails and the keel, and the concept of maneuverability, which is the vessel’s ability to navigate and change her course with the minimum action of the rudder, are discussed.

Afterward, the instructors introduce typical keel and rudder profiles and configurations and discuss sails, rig, sailing areas, and sails distribution.

The course then goes into the modeling of a sailing yacht hull, which is later used to introduce the different resistance components and perform resistance, stability, and performance (VPP) calculations.

  • Once enrolled, you will have access to the virtual classroom, where you can interact with the course instructors and fellow students.


  • To follow the course, it is not necessary to have any prior knowledge of the design of sailing yachts. However, a technical or engineering background will help you out during the journey.

  • A minimum Navalapp membership level of “Subscriber” (free membership) is required to enroll in this course. If you don’t have an account yet, you can sign up for free here.

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.

‘The Science of Sailing’ books (offer)

Course Students have a 20% discount on ‘The Science of Sailing’ books by renowned Naval Architect and Scientist Peter van Oossanen. These books are not required for the course. Read more about this offer here.

Book ‘The Science behind Sailing’ (offer)

Course Students have a 20% discount on the book ‘The Science behind Sailing’ by renowned Aeronautical Engineer and Fluid Dynamicist Joop Slooff. This book is not required for the course. Read more about this offer here.

RINA Endorsement

After a thorough evaluation, the Royal Institution of Naval Architects (RINA) has found that the Navalapp courses Sailing Yacht Design 1 and Sail Design 1 meet the requirements for Continuing Professional Development (CPD) of the members of the Institution. Therefore, RINA has considered that the courses warrant their recognition and has issued a Certificate of Endorsement.

During the evaluation, RINA studied different aspects of the courses, 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 instructors’ expertise, the method by which the students are evaluated, and Navalapp’s organization standards.

Welcome aboard and enjoy the course!
