Not only does the HSF go a bit faster, it maneuvers in ways no "ship" could,
and stops in distances even much smaller yachts couldn't dream of.....
Again....."apples and oranges"..... this class of boat/ship, needs to be
thought of separately.

Hmm, well mostly that the HSF goes a bit faster.

P&O used to have a 35 knot monohull ferry in the Irish Sea, now replaced
with a wave piercing catamaran. The SS United States average 35.59 knots
in 1952. Visby is a conventional RoRo with a design speed of 28.5 knots.
There are also the eight fast cargo ships operated by the US Navy with a
cruising speed of 30 knots.
