I totally agree it sounds incredible, and is only being discussed because the available data gives us that 3 hr figure of 19 kts:
2012-Oct-28 13:33 N 34°38' W 073°21' 58[nm] 19.1[kts]

On the "for" side we are dealing with a ship in a hurricane, not on a regular clipper run, and it is only for three hours. With following winds blowing that massive stern and freeboard down surfable waves it might just be possible for a 180ft vessel to cover that much ground (if the SOG calculation included significant favourable current, such as a gulf stream back eddy). But I have no experience of the sailing characteristics of a tall ship such as the Bounty.

On the "against" side, if you scroll down the data log for the reported positions on the 26th you get a 9 min log of distance run of 8nm at an average speed of 54 knots!!!
2012-Oct-26 13:33 N 39°37' W 071°15' 8 54.0
So that data must be incorrect (unless someone took the beacon for a short helicopter ride). Does anyone have experience of the Ship tracker, and its reliability (or otherwise)? Is the fact that both entries show a time of 13:33 in anyway significant?
The ship's log or a crew member could shed some light...
