Are there any ferries that can hit 200 km/h? Because that's what it would take to get reasonably far from the city.

Only half of it:

Maybe a future revival of https://en.wikipedia.org/wiki/Ground-effect_vehicle ?
Or some shiny airtaxi vtol running on renewables, electricity, handwavium?

Or just a hybrid HTHL vehicle, think SpaceShipTwo with an additional airbreathing engine and some thermal protection instead of a fancy feathered system (not feasible at high velocities). Take off on a quiet engine, get away from cities, make a rocket-powered suborbital jump, vomit in between, re-enter, land quietly across the pond.
(still sounds handwavy and not very realistic, though)

That sounds like Reaction Engines Skylon / Lapcat A2.
All the check-in gets handled on shore, then a fifteen minute ride out to the platform on a high speed ferry, 20 minutes to onboard, then 30 minutes to any other offshore platform in the world, followed by a 20 minute offboarding, and another fifteen minute ferry ride.
The actual travel time would be less than the time you're expected to wait in the airport prior to boarding an international flight.
