Pointing-so whats that all about?

   The angle at which a boat points is the sum of its aerodynamic and hydrodynamic drag angles.  Drag angles are the arctan of lift/drag ratios.  So, better lift/drag ratio = higher pointing. Given that lift is largely limited by righting moment, the best way to improve pointing is therefore to reduce drag - of the underwater and above water parts.

	Following on from a good thread on the Star event. It was mentioned how high they point . So why is that? What makes some boats point and others don't, and how can some sailors get boats to point higher than the rest?
