Pumice is composed of highly microvesicular glass pyroclastic with very thin, translucent bubble walls of extrusive igneous rock It forms when volcanic gases exsolving from viscous magma form bubbles that remain within the viscous magma as it cools to glass When larger amounts of gas are present, the result is a finer-grained variety of pumice known as pumicite.

That would be a little different than the Roman concrete that used volcanic materials, and probably lighter. Pumice doesn't exist boat sailing through pumice english large boat-sized chunks that you can carve into a boat. It's made of smaller pieces of unreliable composition. You need a resin, or a binder like used for concrete, to stick it all. Then you build a mold to shape the thing, fill the mold, and let it set.

You could instead try making planks out of the bound pumice, but that would result in a boat sailing through pumice english boat. Also, pumice is swiss-cheesed with holes. Water must be kept out, which is accomplished by the resin. Careful - fill too much of the internal pores with heavier-than-water resin and abruptly you have something which doesn't float anymore. At this point, you're using a tremendous volume of not-very-strong material as the outer walls of your boat.

Pumice is fragile, and boat sailing through pumice english could step a foot through or drop a hammer through it. The fundamental problem with the idea of a pumice boat is that the floating ability of the raw material is not as important as the airspace in the middle of the boat.
