`Limit commands applying to the IMO HSC criterion where the required

`area depends on the termination angle.

`If the angle of maximum RA is less than 30 or downflooding, then the

`following limits can be used:

UNITS MT

LIMIT AREA FROM 0 TO MAX AT 10 > 0.165

LIMIT AREA FROM 0 TO MAX AT 30 > 0.055

LIMIT ABSOLUTE ANGLE AT MAX > 10

`If the angle of downflooding or 30 occurs before the angle of maximum RA,

`the following technique can be used:

MACRO FINDFLD

VARIABLE FLDANG

HEEL = 0

RA /STOP:FLD /HOLD /NOPRINT

SET FLDANG = {HEEL}

HEEL = 0

/

MACRO LIM1

UNITS MT

VARIABLE T

SET T = 1.65 DIV %1

LIMIT AREA FROM 0 TO %1 > {T}

/

.FINDFLD

VARIABLE A

SET A = {FLDANG}

IF {A} > 30 THEN SET A = 30

.LIM1 {A}
