Seaworthy means fit and safe to go to sea. A seaworthy vessel, barely seaworthy, declared seaworthy.
It is a legal standard rather than an opinion, and a shipowner warrants seaworthiness in every contract of carriage, which is why an unseaworthy ship voids the insurance. It covers the crew and the equipment as well as the hull.
