These sail 'boats' are quite insane with their levels of engineering.  Without an engine, it's purely about aero/hydrodynamics.  Very fascinating after watching F1 cars innovate.

The sport itself isn't as exciting.  I'm sure it's very intense to participate in, but wheel to wheel racing is hard to replicate when you have to worry about random winds and currents.
