OUPV & 100-Ton Master · Stability
On a small passenger vessel, the danger of allowing all passengers to crowd to one rail to view something is that it:
- AImproves the vessel's trim
- BShifts the center of gravity off-center and can cause a sudden, dangerous list or capsize✓ Correct
- CHas no effect on a vessel under 100 GT
- DOnly matters at anchor
Explanation
A sudden transverse weight shift moves G toward the crowded side, reducing the righting arm and producing a list — on a tender or overloaded vessel this can capsize her. Operators must actively manage passenger distribution, especially when wakes or turns are involved.
