Moment to Change Trim by 1 cm (MCT 1 cm)

Compute MCT 1 cm from longitudinal metacentric height (GML) or waterplane moment of inertia (I_T).

MCT 1 cm: — t·m/cm

Equivalent per inch: — t·m/inch

Notes

A) From GML: \( \mathrm{MCT_{1cm}} = \dfrac{\Delta · GML}{100} \)

B) From I_T: \( \mathrm{MCT_{1cm}} = \dfrac{100 Δ I_T}{L_{pp}} \)

Result gives the trimming moment in t·m needed to change trim by 1 cm.

A) From Δ and GML
