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.

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!
