Ok, so a fully-geared 130 footer has "recorded" only a few knots less than the speeds an 8 footer has AVERAGED over 500m.
A cat that big doesn't decelerate fast. It is very likely that they ran over more than 500 meters when the speed was recorded. But this is not important. A windsurfer is amazingly fast for its simplicity and price. A monster multihull is expensive and complicated, but more consistent overall. Not much to discuss, really.
