Upright & trimmed float
Solve the free-floating equilibrium from a target displacement or draft. The full hydrostatic table — drafts, coefficients, wetted area, TPc and more — computed on the exact hull surface.
From upright equilibrium and GZ curves to tank tables and lines plans — pictured here as it runs natively inside Rhinoceros.
Solve the free-floating equilibrium from a target displacement or draft. The full hydrostatic table — drafts, coefficients, wetted area, TPc and more — computed on the exact hull surface.
Sweep the hull through heel with free-to-trim equilibrium at every angle. The GZ curve is checked against intact stability criteria, with pass / fail shown per rule.
Turn closed volumes into tanks and calibrate them level by level — volume, fill percentage and centroid at every height, ready to export.
Combine lightship, tanks and deadweight items into load cases. Free-surface moments and the fluid VCG correction are applied automatically.
Every weight item lives as a point on the 3-D model, linked to Notilus Weight. Move a point in Rhino and sync it back — geometry and weight data stay one.
The sectional area curve of the floating hull, sliced from the exact submerged solid of the last equilibrium — a live check on fairness and volume distribution.
Generate the lines plan and the offset table straight from the hull — set station, waterline and buttock spacing, then add both to the document or export to Excel.
Full intact stability check with GZ curves and load cases delivered from the Rhino hull.
Tank calibration and sounding tables computed live from the modelled compartments.
Lines plan and offset table generated from the exact NURBS hull — exported to Excel.
HydroStab works directly on the exact NURBS hull surface — no export, no re-mesh.
Free-floating equilibrium, hydrostatic tables and GZ curve checked against class rules.
Combine lightship, tanks and deadweight items — with free-surface moments applied automatically.
Lines plan, offset table and stability booklet — exportable straight to document or Excel.

Notilus HydroStab is part of an end-to-end marine engineering toolset. These plug-ins share the same Rhino hull and keep hydrostatics, weight and structure in sync.
Weight items live as points on the model — updated in Weight, sensed live in HydroStab.
Steel structure on the same hull — feed structural weights straight into HydroStab load cases.
Composite laminates and hull weights that roll up into HydroStab's stability calculations.
