Boat hull plate area calculator
Estimate the aluminium plate area needed for a boat hull from principal dimensions. Use the result to feed the weight calculators.
Hull dimensions
Plate & fit-out
Formula
Area (m²) ≈ (bottom + 2 × side + deck + transom + bulkheads) × allowance
Use consistent units: the calculator works in the dimensions shown. ρ is alloy density in kg/m³.
Example
A 12 m hull with 3 m beam typically needs 80–120 m² of plate, depending on deadrise and number of bulkheads.
