I believe the "scantling" terms that apply for measuring depth and
thickness of components such as frames,stringers, etc. would be called
"moulded" as in depth of a frame(or other member)and "sided" refers to the
thickness. That which lays against the side of the boat(perhaps) An example
might be: an oak frame with planking attached may be 1" sided and 3"
moulded. MIKE

Scantlings are more than just dimesions....
A stringer near waterline level in the boat might be 2in by 3in..... if i
said 2in high and 32 wide... you would not know which was what because the
component is angled in its correct position at about 45deg.............
Scantling give the dat in a form that elliminates the possable
confusion...
(cant remember right now the details)
