That's Antoine Albeau going 49.09 knots at Les Saintes Maries on the March 5th. But wait, that's not a gaff rig...it's a windsurfer. Well my homies, you're wrong again. Check it:
How is it that a lowly, ordinary windsurfer out performs huge, million dollar sailing machines? They're the fastest, and yet they have several huge disadvantages: they're small relative to the wave size, the sails are small and low experience the highest wind gradient, and they have a huge bluff body (the sailor) standing to windward of the sail. In spite of those obstacles, they are the fastest. Why? Because of the awesome gaff rigged sails.
