Question: Is beam normally measured at the waterline? 99% of the definitions I've read state that beam is measured at the widest part of the boat's structure. The waterline beam measure makes much more engineering sense. Which is correct?
Beam stated in brochures etc is pretty much always max beam.. waterline beam is useful to determine hydrodynamic properties of the hull form, and the difference between BWL and BMAX gives one an idea of the flare of the hull design.
Yours is an interesting project and I wish you the best.
