Stability simplified

Years ago, I often gave a lecture to S.E.A. students and other groups that was intended to provide an understanding of basic stability concepts with a minimum of math. It was quite popular at the time so I recently put together a web version of it. It's still a first draft and I haven't yet linked it from my web site since I plan to work on it some more, probably next winter at this point. I've provided the link to a couple of forums and groups though as the feedback and comment I've gotten have led to some useful clarifications and improvements.

I still can't post links so put the standard http thingy with the colon, two slashes, and three w's in front of rogerlongboats.com and then "/Stability.htm".

Thumbs up Wow

That is very well done over all - although there is a typo in the line "In addition to spending nearly four decades tying (successfully) to insure..."

As I stated in my first post I designed a couple dozen power boats (sailboat market had just gone splat) in the 1980s. I still follow and am interested in yacht design. I am also unfortunately still looking forward to my purchase of that first larger sailboat.

After 35 years of voraciously reading everything I can get my hands on regarding yacht design I have never heard CG and especially buoyancy explained like that. I will have to go back and re-read them again as I think my old fart of a brain is having trouble wrapping itself around it.

The best I can come up with is a quote from a TV character who shall remain nameless "A difference that makes no difference - is no difference!"

In any case thanks for the good work...

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.
