Rigging Formulas Upgrade Your BrowserAs I said previously, there are few things of my invention, in these texts. In preparation corresponding to 2013 - Spreadsheet for power determination according to the method Holtrop-Menem. SCT also includes various modules to perform calculations ISO 12215-6, 8 and 9. It also has a module for calculating continuous beams and large facilities for manage the various materials used in the construction of modern boats. The latest version SCT R.14, in preparation, will include the module MyR. Attached is a file that describes the calculation procedures followed by the application MyR. This is not an original method at all, but extracts of texts by other authors. At the end of the text a reference to the authors consulted is done). ![]() Rigging Formulas Download From MyMyR software, as stand alone application, will be available in a few days to download from my website. For now, overcomingthe difficulties an English translation not entirely correct, I would like to have your comments and criticisms, constructive if possible, on the attached text. Hi Ignacio, congrats for your MyR module I also made some years ago an online utility for Rig and Mast calcs, I think it didnt become popular because of the extremely tedious input of data. ![]() Table-data are not working right now. Rigging Formulas Pdf File DoesYour.pdf file does not includes mast and boom profiles data. My recomendation is to include some well known mast builders and rigging catalogues, like Selden (attached). The software should pick the best mast and boom profiles (and wire-diameters) for your inputs. At least, that was the way my online-skedule used to work). Im not sure that the distribution of the force on the sail, in force at the top and on the boom, is correct. Raise then the equations of equilibrium will be more easy task. Others, such as Mr. E.Sponberg, make other distribution of forces. Current study is limited to a few cases of many that can pose a rig. It is generally limited to what the NBS indicates, extending it to the case of three spreaders. NBS method takes many simplifications (eg, a linear analysis of a phenomenon that is three-dimensional) which leads to, as you say, an oversized rig. However, these simplifications achieved that the method is very easy to apply and very suitable for translation into any programming language. Classification Societies, for example GL, have matrix calculation methods, more accurate and rigorous but difficult to apply to some not technical designer. I hope many more people will be encouraged to comment on the issue. The list of materials and design stresses are those that ISO 12215-5 standard says that can be used.
