Re: Pros and cons of steel sailboats
While I do not know boat numbers etc, I do understand to a degree other numbers, Yes, doing numbers to do numbers is not a good thing. On the other hand, to know the correct numbers for the task at hand.....that is good to know, or understand.
I had to build a block wall for a client a number of years ago, I know the wall block and design needed to be beyond the general spec. Bid the job and got it per the way the I thought it should be, based on other numbers added. Glad I did, as a few months later the nisqually quake hit. I had it designed then built it with some earthquake added material. Glad I did that. Meanwhile the $100K/30K lb motor home that was parked 3' away from teh wall was fine etc. If it had been built as one person bid it, the wall and MH would have been behind the yard in a collapsed heap!!
Another job, and engineer designed a wall using a different wall block than I typically use. Even got it passed the city inspectors and approved by there DOT folks. I looked at it and said it would not work, put in a different design and got it approved, and built accordingly. This wall had Metro buses running 5' from it, with a concrete sidewalk above it, the wall block in this situation was not designed to hold this type of both static and active load on it. Neither wall block design was in all honesty, but one had to know that one needed other reinforcement to make it work.
Hence why I believe with all math issues one has to have ALL the factors built in, not just some of them!
She drives me boat,
I drives me dinghy!
