OK, so floating isn't THAT special...but a board that can lift a 360lb boat and two sailors while under sailing load and still be light enough to easily float in water is pretty cool.
Sorry Jake, but a density below 1 is not really a feat, especially if it is achieved using carbon/epoxy/honeycomb cured in an autoclave (supposing that this is how they are built).
My not-post-cured glass/estervinylic/foam foils lift a boat that is over 2000 lb (approaching 3000 lb fully loaded) at less than $1300 each. I don't think their density is remarkable, if anything I would bragg about their price
