This episode of the Dropping In Surf Show features Mark Buetzow, veteran ship designer, sailor and water-skier.  Rob and Mark discuss various hydrodynamic designs, different types of drag, forms of propulsion, and design spirals.  Mark had a knack for understanding surfing, despite never surfing in his life - it’s fascinating to hear what a natural he is.  Must be something to hydrodynamics!
