Yep, widths are with respect to centerline. So 20 inch beam means X=10.

But use the full displacement.

: I've got a question for those using the free hull software found on:
: http://www.carlsondesign.com/#Professional_Shareware

: What are putting of a beam?
: The full beam or half?
: I put in the full beam, and it looked like I doubled it :confused: I checked
: the stations and it was double, since you work with half stations.

: But then which displacement do you use?

: On the brighter side my center of bouyancy along lengthwise, stem to stern,
: is right where I predicted it!
