: Well at least it is means to compare boats on the same level! After
: applying it to a few I find it pretty useful. I know what to
: expect from a boat with 100 or 92.
: BTW Free ship doesn't give this, I have to calculate it.

: Here is the quote from Bear Moutain boats:

: Stability Factor
: We wanted to give our customers a reference for the stability of
: our boats. Our designer Steve Killing came up with the stability
: factor: the technical description is at the bottom of this page,
: but the real value is in comparing with other boats. Numbers
: range from about 70 to 120 - the larger the value, the greater
: the sideways stability. Many novice kayakers find boats below 95
: to be just a bit skitterish, around 100 to be average and over
: 105 to be very stable. Your experience level will determine the
: stability you need. ....

I just like terms that are more defined I guess :)

Would be more helpful if the author had done these calculations on some production boats so you'd have an easy reference.
