OUTPUT REFERENCE POINT（RFP），DISTANCE FROM GLOBAL ORIGIN：
ABBREVIATIONS
BASELINE：Longitudinal co-ord. axis through output reference point.
DRAUGHT AT L/2：Draught at midship above RFP.
DRAUGHT EXTREME：Draught at midships above the extreme draught datum point.
NORMAL DRAUGHT：Draught at perpendiculars measured normal to base line,multiplied by the cosine of the angle of heel.
DISPL TOTAL SW：Total displacement in sea water.
DISPL TOTAL FW：Total displacement in sea water.
DISPL TOTAL：Total volumetric displacement.
DISPL MLD：Moulded volume of displacement.
LCF FWD OF REP：Long,centre of flotation forward of output reference point.
TCB FROM RFP：Transv,centre of buoyancy to starboard of output reference point.
LCB FWD OF RFP： Long, centre of buoyancy forward of output reference point.
LCB FWD OF REP：Long, centre of buoyancy forward of output reference point.
VCB ABOVE RFP： Vert,centre of buoyancy above output reference point.
KMT ABOVE RFP：Position of transverse initial metacentre above output reference point.
DFLP：Down-flooding point.
MS：Stability lever about initial metacentre.
PN：Stability lever about a given point P on a vertical axis through initial centre of buoyancy.
AREA UNDER CURVE：Integral of MS of PN curve from 0 to given angle of heel.
NOTES
CALCULATION OF STABILITY LEVERS ARE BASED ON MOULDED LINES.
