Draft Survey Calculator
Full quadratic-mean draft survey — for any bulk carrier, using your vessel's own hydrostatic particulars.
🚨 Planning and cross-check tool — not a replacement for your vessel's approved loading computer or stability booklet. Verify against your ship's own hydrostatic data before relying on the result for cargo settlement.

Hydrostatic Table (from your ship's stability booklet)
Paste rows from your ship's own hydrostatic table — one row per line: Draft, Displacement, TPC, MTC, LCF (tab, comma, or semicolon separated). You don't need every 0.05m step — the tool interpolates between whatever points you give it. More points = more accuracy, especially near your operating draft range.
