some small block I/O setup because it fit the parameters of speed and
milage while I'm on the side of beating the parameters.

Most small block I/Os that I'm familiar with get around 2 nmpg, maybe
2 1/2 on a good day. Those boats are way too small to cruise on big
water for 1400 miles without getting beat up pretty badly.

I think a power cat around 30 ft with diesels is about right but even
they would need a halfway decent weather window for the offshore part
of the trip.

Anything much bigger than that will either not have the speed or not
have the fuel economy.
