Hydroptere as not been built for 500 m speed record, but for médium distance open water speed records.
"February 9, 2005: The symbolic cross-Channel record by airman Louis Blériot in 1909 is smashed by Hydroptère in 34 minutes and 24 seconds with an average speed of 33 knots."
It's the same ship but modified for short distance, that break the wall.
For "Banque populaire V" not a foiler, but look at the retractable center-board.
These ships are not built for absolute speed records, but they can run at an incredible speed even in rough sea.
Next step, around the world between november 2009 and january 2010.
