🔍 Key Concepts

• Longitudinal moments = weight × longitudinal distance from a reference (usually amidships) • When you transfer weight internally, one tank loses weight and another gains the same weight • Moment changes depend on both the distance moved and the direction (fore or aft) of the movement

💭 Think About

• Identify the longitudinal distances (LCG positions) for tank 1P and tank 10S from the reference and find the distance the weight has effectively moved • Determine the sign of the moment at each tank location (is it forward or aft of the reference?) and how that affects increase vs decrease in total longitudinal moment • Multiply the transferred weight by the effective longitudinal shift and compare the result with the answer choices

✅ Before You Answer

• Be sure you are using long-tons (not metric tons) and that the unit matches the moment table in the stability booklet • Confirm whether the reference point for moments is amidships or another specified point and use the same reference for both tanks • Check your math: the change in moment should equal weight × distance moved, with the correct sign (increase or decrease) based on direction of transfer
