Ericsson 4 the Volvo 70 with skipper Torben Grael has sailed 585 miles in 24 hours; a new monohull record. Rumor is that they may exceed 600 miles iin the next 24 hours. This is a really hard thing to accomplish; to be able to maintain these speeds for extended periods of time. It is the adrenalin rush that keeps crews returning for the punishment they receive in return.
Speedboat, probably could not achieve these speeds, except under ideal conditions, strong wind well aft, a regular sea state, not too confused. And then probably not for several days in a row.
