Hi Lazeyjack, Nice pictures you have in your gallery. Was the m40 built to german lloyds or lloyds? I would like to use only transverse frames...
Hi Bijit, I am taking the attached plate into account, I have sent German Lloyds an email to ask them this as it wasn't immediately clear. They...
Jim, I think you will get an answer, so far they have always replied to my e-mails. Might take a few days tho.
Peter, I have a roundbilge design, so hardly a sharp deadrise. But to be safe, I just use the section modulus from the center to a quarter...
Thanks Dutch Peter, From what I remember in the past (some 12 years ago, in the Netherlands) we used to call the thin flatbars running from...
Hi John, You suggested that I should use 250 mm for the spacing of the stringers and 800 mm for the webframespacing. I tried to do this, but...
Hi all, I very kindly received an answer from GL-Group regarding the effective platewidth. The answer is below: =============== We could confirm...
Thanks John, I have researched the GL rules, but I cannot find anything regarding the effective plate width in those rules for metal hulls. They...
Hi John, Forget the question about the unsupported span of webframes, this is clearly stated in the rules (just looked them up), it is like I...
Hi John, Typo's are very easy to make, I will recheck my formula. A transverse framespacing of 800 mm also sounds acceptable to me when...
Hi Brent, Thanks for your reply. I haven't looked into this building method, but to me it sounds a bit scary, but this is probably a lack of...
Hi John, Do you have an e-mail address I can sent the rules too (they are available freely on the internet) and the numbers I have used for the...
Hiya, I did already look at the Dave Gerr book, it is an ok book I think, but I have a problem with his framespacing. In my case Dave Gerr...
Hi Olav, I understand your confusement... First of all it is indeed cm^3, the software I use to calculate the section modulus of flatbars etc is...
Hi Mike, You are right about me getting confused. I do have the rules in electronic form and in english, so I will send them to you. I will...
Hello Dave, Thanks for you reply. This is how I got to the amount of money I got to (I roughly added it up in my head): Pricing is from your...
Thanks for the replies so far. For what I am looking for, I think westlawn is a bit too much (will cost about 15000 euro's for the 4 modules...
Hi all, I am wondering is there a Yachtdesign course in the Netherlands, something like Westlawn? Grtz, Arvy
Hi all, I know crossposting isn't the way to do things, but as I didn't get any response to my questions in the Class society subforum, so I...
Hi all, I am still puzzled with the germanische lloyd rules. I am designing a steel 40 ft sailing yacht, and right now I am working on the...
