I’m thinking it must have been armor plated.
It has a water tight forward bulkhead and the bow has port and starboard anchor plates as well as a thick stem plate on the bluff bow. From photos it looks like she has a 24 mile radar mounted above the 72 mile radar which is positioned between two satcom units. https://bahamaspress.com/government-statement-on-the-collision-of-gas-tanker-and-yacht-in-bahamian-waters/ with photos
