I don’t understand given all the lifesaving equipment, how no one survived
Life saving equipment doesn’t mean much if a ship is literally overwhelmed by a storm. What I would like to know is how well-equipped the ship was with navigational equipment. GPS equipment can immediately mark a location where a vessel goes down and continually send out signals. On top of that, there are EPIRB devices that a sailor can wear, and many lifeboats and PFDs are equipped with them that give out information as to their location.
