"Waterplane" and "underwater profile"
Posted: 30 Oct 2005, 02:49
Ref: Class Rules D.2.2
Is "waterplane" the section through waterline, or something else?
Is "underwater profile" restricted to that (wet) portion of the hull beneath water when at rest in calm, or to any surface that might become "underwater" -- such as, the deck when the boat dives in a blow?
Is the "underwater profile" any particular one (such as transverse sections perpendicular to the centreplane), or any (sectional is assumed) profile at all?
What's the distinction between "underwater profile" and "undersurface" (which is illustrated at the end of the Rules)? Does the latter include aspects of the former?
