Why aren't we crossing the ocean on a boat in "hours" yet?
Forums:
What's the sticky wicket, physically speaking? Even if the ocean were "glass" (no waves), does it still all boil down to friction? What about some form of what might be the equivalent of "levitation" technology we see with high speed trains? Will this always be the case, or will this be a nut that is cracked eventually?

Yes it boils down to friction. Levitation is like flying in an airplane. Levitated boats will lead to threads about how bad everyone is treated like on an airplane.

^ If these smaller boats can push 300mph, why couldn't there be much larger versions that are "scaled up"?

Does it mostly boil down to economics? If so, I imagine there'd need to be a breakthrough in technology vs. simply making a giant speed boat.
As to VIP: it's not necessarily people, but cargo ... especially in a world that is far more interdependent. I realize there are big planes, but they pale in comparison to giant cargo ships.
^ I know this isn't the "answer" some of you are seeking, so here you go: if a ship can cross the Atlantic in 6 hours, that's a relatively small amount of time that "Mr. & Mrs. Grey Poupon" could lord it over the common folk vs. traditional sea voyages. It'd be kind of like flying first class in a new version of the Concord that only takes 30 minutes to fly from NYC to London.

What type of wake would be created by a vessel traveling at 170 knots?

Water is over 1000 times as dense as air. Chances are that there is no material that wouldn't deform or explode being plummeted by such mass at the speeds needed in your example for any length of time. Friction would also come into play because of the heat generated would not only melt any known hull material but also vaporize a large portion of the water it travels through. Add to all of that the amount of energy to get something the mass of a large cargo vessel to the speeds needed would probably also make this a very non=green situation.

Currently, a large container ship does about 30 knots and takes over a mile to stop.

It would be more economically feasible to construct some type of floating causeway with rails laid upon it.
I have no source for this feasibility other than a (somewhat) functioning brain and deductive logic.

if you ever make it on to jeopardy, and can somehow fit that into your introduction, you could possibly become the first ever instant winner.

Forty Knots & No Smoke
Forty Knots & No Smoke
During World War II and the years that followed, sailors from the Navy's far spread battle groups participated in an informal competition to run their ships at forty knots with little to no visible smoke bellowing from the stacks. The absence of smoke and coal ash meant every sailor on board was working with the utmost precision and that the ship itself was cutting through the ocean at peak efficiency.

Actually if you want to commute rapidly through the Ocean, there is the "Torpedo" which goes underwater. Pack yourself in one of those, and you will save time.
I can't imagine that the various Naval Research Groups have ever tried such a thing.

The fastest way to cross the ocean w/o resorting to flying would be a sea-bottom vac. powered capsule in a tube.
Very costly to build, however.

Japanese thought of it.... for suicide runs... Kamikaze torpedo . 1 pilot sealed in. Lots of explosives. They would drive it into a ship.
"American losses credited to Kaiten attacks came to a total of 187 officers and men. The losses of Kaiten crews and support staff were much higher."
I'm sure the cartels have perfected it for cargo.
