Input/Output, Hydrostatics for One Waterline (English
automatically computes hydrostatics characteristics for
one waterline. If the waterline is level this data may be used as an
input source for the vessel's "Curves of Form."
Though optional, this spreadsheet is best utilized in
conjunction with a Displacement Sheet (Product
Disp-e) and a
Waterplane Sheet (Product
further enhancement is combining this sheet with a Displacement sheet and
a Waterplane sheet. In fact a product is available that combines all
these sheets together, it is called Waterline Hydrostatics Data Sheet
WL-hydro-e). This combination facilitates faster and easier
computation for a given waterline. In the combined case calculations
are more automated, significantly minimizing entry input time.
Document Type: Microsoft Excel
Pages: single sheet
- Items related to half breadth inputs:
the waterplane area (AWP), longitudinal center of floatation
(LCF), longitudinal moment of inertia (ILCF) and transverse
moments of inertia (IT). This data is
normally obtained from a waterplane sheet which involves half beam
characteristics. Hawaii Marine's waterplane sheet, product
WP-e, would work
here. Alternatively calculative results obtained by hand
calculations, CAD output, planimeter or some another source may inserted here.
Optional Input Items:
automatic output generated are the tons per Inch (TPI),
longitudinal metacentric radius (BML), transverse metacentric
radius (BMT), distance from keel to longitudinal metacenter
distance from keel to transverse metacenter (KMT), bock
coefficient (CB), prismatic coefficient (CP), and miship's
