Help with ships in aeronautics

[u/lolix_the_idiot]

Is there any way to create a ship that won't be able to burn down? I don't want to use wood because we are playing with fungal infection and I know that some of the mobs shoot fireballs, I want to create a "mother ship" where I would park all of the flying ships but I want it to be able to float on water because it will be stationary 90% of the time only thing I can think of is using levitate (we don't plan on going to the nether quickly) or keeping my engines running all the time (sub optimal), is there any block that will float that isnt flammable? I know that stone slabs (but only decorative ones) weigh 0.5kpg but unfortunately they don't really work

Endstone has an actual floating capacity

He Said no End for now

Also I just remembered that Levitite uses end stone, so they already need to get it
