WHy 2 engines on one shaft.... you still have a single point of
failure... the shaft/wheel/tranny.
Why not follow Nordhaven.... single engine + a wing engine
OR
2 generators... 1 main electric motor + 1 wing electric motor.
no single point of failure
I worked in Helsinki at Wartsilla shipyard many years ago and all the
icebreakers and cruise ships use electric power.

Actually, that's very interesting, thanks. After you sent me this link
I found another site that has much of the same information, www.feys.org.
That site at last puts a price tag, one of $73K, on a system with 4 x 133hp
electric motors plus a 400kW diesel generator.
Which in fact is exactly what I want - except for more generators, which
they say is an option in their system.

The price is actually lower than I expected and I suppose doable for
a ~30m steel ship that needs to be repowered anyway. Remains to
be seen if the figures they give hold up in reality though. Plus,
I don't suppose the price includes installation.
Actually, that feys site is the one I remember seeing years ago, googled
for it but the bugatti site came up first so that's the one I posted. I
think bugatti makes the systems feys installs so either one would be a
good resource. But you're right, I do like the feys site better. More
information there.
I don't think their price includes installation. But if everything
they're saying is true, installation should be a breeze compared to
installing a conventional engine. Probably a little harder than
replacing an engine in an existing installation but maybe along the
lines of converting from gas to diesel.
I'd like to hear your progress if you go with that system. I saw it a
few years ago and thought it was a great idea if I was ever going to be
a powerboater. But I'm a sailor and don't need that much power.
