TPC & MCTC Calculator

Approximate TPC from waterplane area and basic MCTC estimate.

Approx MCTC —

Formulas used

TPC = (Waterplane Area × Density) / 100

MCTC (approx) = (Displacement × GML) / (100 × LBP) — simplified estimate when data limited.

Note

Accurate TPC and MCTC should always be taken from the ship’s hydrostatic tables. This tool gives a quick approximation only.
