... there on a wood floor just burn that :) also the roof as that would heat up a bit as well :b stuff it live in a giant fire {jk devs dont set my raft on fire plz} but i wouldn't lite a fire so open on a wooden raft make it cost more and combine cooking and boiling into a closed fire with a chimney you can put threw the roof. (that uses wood and matches etc to light maybe even paper you have to dry first cant be that hard to find in a ocean were metal floats)
