    variable MH1
    MH1:={GMT} * {WEIGHT} * 0.01745   `0.01745=1 degree in radians)
    \Moment to heel one degree
    \Calculate moment to heel one degree from GMT system variable:
    \   GMT ({GMT:2}) * WEIGHT({WEIGHT:2}) * 0.01745 = {MH1:2} {LUNIT}-{WUNIT}.
    
    
    \\Alternate method using RAH system variable:
    \Calculate moment to heel one degree from RAH at HEEL 1
    heel 1
    solve trim
    \   RAH ({RAH}) * WEIGHT({WEIGHT:2}) = ({RAH*WEIGHT:2})
    
    \\The values will be closer with tighter station spacing.
