- AIncreases freeboard
- BShifts the center of gravity off centerline, heeling the vessel and reducing stability✓ Correct
- CImproves trim
- DHas no effect on a powered vessel

A transverse shift of passenger weight moves G off the centerline and can heel the vessel, lower freeboard on the low side, and—combined with free surface or a turn—lead to downflooding or capsize. The master must control passenger distribution.
