A flood would be currents of water but not necessarily waves you see on an ocean, would it?

The whole "sea" (whole earth actually) must be taken into account. The variations in air pressure on one part of the globe will have impacts on others. This isn't just a "filling up your bathtub scenario" unless you've thrown a couple of active toddlers into the tub as well.
Also, your rising scenario ignores the scouring of rock that many Young Earth Creationists want to attribute to the "Flood of Noah." (See the Channeled Scablands for example and even the Grand Canyon).
These same folks want to have had the continents "separate" at this time. North America isn't going to move over 4,000 miles in a few months very quietly. There will be rough seas. I know you may not want all of their baggage, but it's worth adding here.
The lateral stability necessary to keep the raft from flopping upside down would require displacement such as you would have with a hull and keel design that you've already mentioned. This would also provide some longitudinal rigidity. This is necessary for keeping the whole vessel from snapping in half. Even without propulsion, the vessel will at times be lifted up so that one half of its weight is bearing downward on the keel. This action will be repeated with every wave.
So, we must have a keel that is strong and rigid enough for stresses that are to be equated with a huge hand lifting the vessel by its stern and shaking it up and down.
A wooden keel of over 300 feet in length has never been sufficient for sea keeping. Not ever in the history of man. And, Noah's Ark is described as being 66% longer than that.
A covered deck on a raft would have to be sufficient to shelter its passengers from the waves generated as India and the Himalayas passed underneath at speeds of about 3 or 4 knots. In other words, no shelter would be sufficient short of a rigid steel vessel in orbit at a distance of at least 120 miles from the surface of the flood. (Lower orbits would decay too fast).
