Thanks for the comment! Much appreciated. We are going into the details of FEA in the course. You will find more information about it here: navalapp.com/courses/finite-element-analysis-for-marine-structures/

Thanks for the comment. Yes, we are. This is discussed in the course. Indeed, most classification societies usually request the models to be meshed with quadrilaterals. However, you can always try to justify meshing with triangular elements if you mesh enough (smaller element sizes) in the areas of interest because at the end you will have the same number of nodes. As said, this is discussed in the course. Although it is difficult to see in the video, you can see quadrilateral elements on it, for example in minutes 1:36 and 1:46. Many thanks!

Hi, thanks for your comment. This is the link to the summary lesson of the course: navalapp.com/courses/sailmaking/lessons/wrap-up-sailmaking/ It gives an overview of the different topics discussed in the course. Additionally, when taking the course, you will have to work on a final assignment where you have to do a schematic drawing of a sail with as many details as possible as you have learned during the course. The drawing can be made using software or on graph paper. In both cases, it is important to use appropriate proportions of the sail and detailed dimensions as well as provide a general description of the sail, the boat, the rig, sail attachments, intended use, and provide a list of details included (panels, materials, corners and reef webbs, patches, battens, etc.)

Speaking as someone who worked as a sailmaker in my youth, it's perfectly possible to make sails for dinghies or small yachts on a home sewing machine especially if it's one of the old cast iron ones from the 50s and 60s. The Japanese machines from that era were particularly good and can often be bought very cheaply. For learning resources the nearest thing to a "standard work" on sailmaking I know of is "The Sailmaker's Apprentice". A lot of the book is really only relevant if you're making very traditional sails but the basic are there for evenmodern Dacron sails. Here on UA-cam there are series of old videos on Expert Village's channel covering the whole process of making a headsail from design all the way through finishing. And Sailrite's various videos on constructing and finishing sails are well worth watching. Hope this helps.

Hi, thanks for the comment. Yes, weight calculation and distribution are an essential parts of the design. For that, we must consider systems like engines, etc., as well as the hull and superstructures themselves. We can calculate the waterline for a specific load condition when combining the weight and the weight distribution with the hull's shape. Load conditions could be, for example, the ship unloaded or loaded, with or without crew, etc. Everything has to be accounted for and controlled precisely from the design phase until the end of construction to ensure the ship will float at the intended design waterlines. We hope this helps.

@@navalapp Thank you for your reply! It gave me direction. I have always wanted to build a sailboat by myself since I was young, and now that I have time, I plan to try building my own sailboat.

Hola! En este momento los cursos son en inglés, pero estamos anadiendo subtítulos en espanol a varios de ellos. Por ejemplo el curso "Yacht 3D modeling with Rhino - Level 1" tiene ya disponibles subtítulos en espanol (este es el link al curso: navalapp.com/courses/yacht-3d-modeling-with-rhino-level-1/) y estamos terminando los subítulos en espanol del curso "Aerodynamics for Yacht & Sail Designers" (este es el link: navalapp.com/courses/aerodynamics-for-yacht-and-sail-designers/). Actualmente tenemos planeando anadir subtítulos en espanol a más cursos. Esperamos que esta información sea de ayuda!

No, under a barnacle.

Thanks for the comment!

@@navalappI know - but "academic" might not apply forever. And while that might make it more accessible to students, it still is a piece of software that is incredible painful to use. The question was more: Isn't there really no better software to use?

@@tcurdt Yes, there are many other software to use. We may also cover them in future courses. This course is about Maxsurf. Thanks!

Yes. We will. Thanks for the comment.

Un placer!

It's never too late! Thanks for sharing!

Many Thanks!

Sorry for this very late reply. There is no an option in Rhino to find the DWL. However, you could think of some methodology to find, more or less, the DWL by approximations. But, the result would be an approximation and would not consider some other aspects like the trim or heel. But some specialized plugins (software) running on top of Rhino can calculate that automatically. One of them could be Orca3D. You can also design the hull in Maxsurf, and once you have obtained the hull you want, export it to Rhino.

Widen hull in aft/narrow bow to move aft. Opposite to move fwd?
