OUPV & 100-Ton Master · Stability — Weight Shift / Crowding
On a small passenger vessel, passengers crowding to one rail or all to one end is dangerous because it:
- AShifts the center of gravity, reducing stability and trim and possibly causing a capsize or downflooding✓ Correct
- BImproves stability
- CHas no effect on a small boat
- DOnly affects fuel economy
Explanation
Passengers are 'live weight.' If they crowd to one side or end, the combined center of gravity shifts, the vessel heels or trims, and righting ability drops — historically a cause of small-passenger-vessel capsizings. The master must actively manage passenger distribution.
