Who is affected and how:

• Cruise lines and vessel owners/operators: The statutory, four-part definition of "cruise ship" changes which vessels are legally treated as cruise ships under this provision. That can alter whether a particular vessel is subject to the rights, duties, or remedial rules tied to 46 U.S.C. 30307.

• Passengers and families (claimants): Defining "nonpecuniary damages" as loss of care, comfort, and companionship clarifies the types of emotional or relational harms that are statutorily recognized. This may narrow or better specify what plaintiffs can recover as nonpecuniary relief under this section.

• Insurers and defense counsel: Clearer statutory language will affect risk assessment, coverage positions, claims handling, and litigation strategy. Insurers may adjust premiums or reserve levels for vessels that meet the new definition.

• Courts and maritime litigants: Judges and lawyers will rely on the new definitions when deciding whether the statute applies to a particular case and what damages are cognizable, which may change case outcomes compared with prior, less-specific definitions.

• Regulators and registry authorities: Any administrative determinations that depend on statutory classifications of vessel type will need to apply the new definition.

Overall effect: The amendment is primarily definitional and clarifying. It may produce shifts in case law and commercial practice where prior ambiguity about what constituted a "cruise ship" or what counts as "nonpecuniary damages" affected outcomes. The changes do not impose funding obligations or new programmatic mandates.
