Regarding trimming of a vessel, and the location of the LCG, LCB and LCF, in which direction, and about which point, will the vessel trim based upon their relative locations? (See Illustration) Illustration RP014

Question

Accepted Answer

Option C: Trim by the head about the LCF.. Trimming moments act about the Longitudinal Center of Flotation (LCF). When the Longitudinal Center of Gravity (LCG) is forward of the Longitudinal Center of Buoyancy (LCB), the resulting couple creates a trim down by the head utilizing the LCF as the pivotal axis.
