There can be mistakes and misspelling, I'd like to get some feedback.

Have fun

hi terho,
does it work for steel hull?

Sure, it's a geometric study really, not depend on materials. You just can't have steel hulls light enough to have decent load capacity. Lenght displacement ratio barely can be more than 5 for steel (should be 6 or more).

Major thanks for these documents as they'll come in handy for a design I'm doing. Good to see that the numbers I'd come up with from my research weren't too far off. A few questions and comments:

1) How can I be sure I have the latest posted version of the files is it just a matter of searching the thread backward to the last posted?

2) I'll be very happy to have the document (PDF) with the references.

3) Personally I think the standards should be free especially if you're an EU citizen after all you pay taxes don't you. In the US the government makes charts (paper and electronic) and they're free while here in England you have to pay for them.

1) The latest published spreadsheets are always here:

2) I'd be very happy to have the time to add the references. Most of the formulas are common NA, basic math and physics anyway. Some are from ISO standards and some (only few and nothing too scientific) are my own findings during my design and study work. It is just a note paper...
