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

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.

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

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.

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 Your numbers are never out of date.

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.

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.

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.

Manage every project and its particulars — hull type, material, length, tonnage, beam, draught — from a single fleet list. Duplicate a vessel and start the next estimate in seconds.
