The format of the DESIGN file, used to import Section Design data, is shown below. The Design file uses a common range of Waterlines to define a fixed 23 displacement stations as follows:
|
Station Range |
Increment |
|||||
|
0 - 1 1.5 - 4 5 6 - 8.5 9 - 10 |
0.25 0.5 0.5 0.25 |

Record 1: |
Principal Dimensions |
|||||
|
LPP B T HS HS ROF NWLS |
||||||
|
where |
LPP B T D HS ROF TH NWLS |
= Length between perpendiculars = Moulded breadth = Draft = Height of topmost Waterline = Half siding of keel = Rise of Floor = Mean thickness of shell plating = Number of Waterlines (maximum No. 22) |
||||
|
Record 2: |
Waterline Heights |
|||||
|
0.0 Z(1) Z(2) ...... Z(NWLS) |
||||||
|
where Z( n ) |
= |
Height of Waterline from baseline for each of NWLS Waterlines |
||||
|
Record 3: |
Section offsets, repeated 23 times for standard stations |
|||||
|
Y(0) Y(1)......Y(NWLS) |
||||||
|
where Y(0) |
= |
Flat of Bottom offset |
||||
|
Y(1) |
= |
Section offsets measured from the centreline at each Waterline |
||||
|
Record 4: |
Stern and Stem Data, repeated NWLS+1 times |
|||||
|
STRN STEM |
||||||
|
where STRN |
= |
Distance of stern profile from the AP |
||||
|
STEM |
= |
Distance of stem profile from the FP |
