Two jet engines for a cruising speed of 60kts -- in a 118' yacht!

probably a big diesel in a tug, the old 2 stroke diesels are prime for that, they allready have a blower just add a couple turbos
all america wants is cold beer warm cat and a place to take a poop with a door on it

a stealth yacht?

Now it needs some serious multiple stage boost controller!. Fueling would be a great challenge but some guy probably cracked that problem to a certain extent.
Why not?. I say, small turbo to get the low-end and SC for the high-end. This is no different functionally from dual stage twin turbos. Make it work is another thing altogether!!. The transition is a very complex thing to achieve in reality.

When a supercharger and turbocharger are used together, doesn't it usually go the other way, with the supercharger producing boost from the drive belt at low RPM and the turbocharger taking over when the exhaust pressure builds?

that's what i was going to say, a small conventional turbo with a **** load of bottom end will overspeed at high rpm where the blower may be running out of capacity. another way of doing it is a 50-75 hp shot of no2 to spool up a big turbo off the line but that only really works on a drag car

why does that look like an M30 oil filter housing?

Fueling would be easy, tuning the beast would be the entertaining bit. this would have some 'functionality' differences to twin turbos, the ramp up to boost would be much better, depending on the control system there could be 'turbo lag' basically eliminated from cruise and efficencies would be better without running an inefficent small turbo when on full boost which would generate a lot of heat. the intercooler would take most of it out but you dont need to create more work for yourself.
The transition point could be set up with two pressure sensors feeding back to the control module, one after the charger one after the turbo. when the pressures are equal, switch off the cahrger and let the turbo do the work. there would have to be a draw through bypass on the charger for the turbo,
i have seen similar setups on a 4AGZE corolla motor, the charger doen not pipe into the turbo, they have seperate intakes and a joined discharge into the cooler.
