many boats have might call double hull, not called. when fiberglass boat made many of better quality boats have hull, , hull liner inside of boat. helps make boat stronger while giving better finished boat. boats (notably boston whaler) fill void between hull , liner foam. make boat heavier having air makes boat unsinkable if cut in pieces. whaler ad shows 1 cut 3 pieces still floating people standing on each section.
ships. oil pollution act of 1990 passed result of exxon valdez oil spill banned single hull ships of 5000 gross tons or more entering or working in waters 2010. required double hull construction of ships 2015 prevent pollution caused groundings or severe hull damage.
