Notilus Weight — weight and centre-of-gravity control for marine projects
← All products

Weight and balance,
under control from first item to final report.

Notilus Weight turns your ship's weight breakdown into a live, class-ready register — every item, category and revision on one screen.

— What's inside

Everything weight control needs, in one tidy place.

From adding items to exporting the report — every weight, category and revision on one screen.

Add items in seconds
01 · Entry

Add items in seconds

Enter each item under its category with quantity, mass and margin, and LCG / TCG / VCG roll up live as you type. A single tick links any item to the Notilus Scheduler, so equipment and weights stay in sync — no double entry.

Structure the whole breakdown
02 · Categories

Structure the whole breakdown

Build the weight breakdown exactly how your class society expects it. Create, nest and reorder categories in one directory — the register reorganises itself instantly.

Stability-ready load cases
03 · Load cases

Stability-ready load cases

Turn your weight data into lightship, departure and half-load conditions. Arms and free-surface moments carry through automatically, ready to drop into stability analysis.

Watch weight & CoG in real time
04 · Analysis

Watch weight & CoG in real time

Lightship weight, global margin and VCG–LCG on headline cards, weight split by category in a live donut, plus weight-monitoring and area-mass views a toggle away. Your numbers are never out of date.

Decide exactly what's reported
05 · Export

Decide exactly what’s reported

Choose which columns appear in the export — item, brand, location, LCG / TCG / VCG, weight, margin, area density and more — with a simple switch for each. Your report, your rules.

One click to a polished report
06 · Report

One click to a polished report

Export a branded, submission-ready document to Excel or PDF — headline figures, full category breakdown and the weight-distribution chart included. Exactly the report your client and class expect.

Never lose a version
07 · Revisions

Never lose a version

Save the whole project as a revision, compare any two side by side and roll the model back at any time. Every change captured, every step traceable.
