Hi Glen,

The remainder of my post was something like:

"Maybe I have stuffed-up the addition of inches to the units" but that seems the likely culprit now.

Glad to hear it was using a comma instead of a point that caused the error you were getting, 'coz I couln't replicate it.

I must admit, I didn't check deeply enough into kayak foundry to see what values it makes available, but I need to.

Sorry for the inconvenience.. Please stick with using feet for units while I do some investigation & release a bug-fix.

Regards,

Phil.

: OK! I was using a "comma" instead of a decimal dot. When I use the
: comma it works. With a draft of 4,4 and a curve factor of 9,44 I obtain a
: stability factor of 5320. Something wrong for sure. KF show a stability
: factor of 77.
