Description
Multiply nonnegative mass by positive gravity and signed transverseShift to obtain a signed heeling moment.
Vessel draft, loading moments, and free-surface terms describe different parts of hydrostatic behavior. Their signs, reference positions, and dimensional bases must be stated before comparison.
Multiply nonnegative mass by positive gravity and signed transverseShift to obtain a signed heeling moment.
When to use this tool
Use Transverse Shift Heeling Moment Term when you need a supplied trim, loading, or hydrostatic component.
How to use the tool and how it works
- Enter mass, transverseShift, gravity. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read moment. Use the output convention below.

}Limitations and assumptions
- Use coherent units, such as kg, m/s², and m for N·m. No heel angle or stability criterion is calculated.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Consult vessel-specific hydrostatic and stability information under the relevant loading condition for a complete assessment.
