Usually making hulls non-rigid makes them slower for given power.

One notable exception: a PortaBote, but that's not practical for most

It is hard for me to believe that is an exceoption.

It would be notable if so. Indeed, it would be a miracle.

Obviously, you haven't run around on a PortaBote. 4 HP gives a solid 10+
knots speed with lots of load.

When the boat goes on plane, the "floor" under the helmsman's feet drops
a bunch of inches. Unlike a solid hull, the PortaBote expands into areas
of low pressure to limit the drag (suction).

If you say so. The age of miracles is not past.
