Calculate the angle of heel at which maximum righting arm (GZ max) occurs
Launch CalculatorThe Angle of Heel at GZ Max calculator is a professional tool for calculating the angle of heel at which the maximum righting arm (GZ max) occurs for vessel stability analysis. This angle is a critical stability parameter used in marine engineering and naval architecture to assess vessel safety and compliance with stability standards. Note that this calculator determines the angle in degrees, not the GZ max value itself which is measured in meters.
Result is the angle of heel (in degrees) at which maximum righting arm occurs
Calculate the angle of heel at which maximum righting arm occurs based on vessel mass, waterline length, beam, and centre of buoyancy position.
Uses industry-standard empirical formulas to determine the angle at which GZ max occurs based on hull geometry and displacement.
Verify vessel stability parameters meet regulatory requirements and classification society standards.
Track project information and maintain professional records of stability calculations for certification.
This calculator provides the angle of heel at which GZ max occurs for preliminary stability assessment. Complete stability analysis including full GZ curves and inclining experiments must be performed by qualified naval architects and verified by Notified Bodies or marine surveyors for certification purposes.
The angle of heel at GZ max represents the heel angle at which a vessel generates its maximum transverse righting moment. GZ max itself is the maximum righting arm value (measured in meters), while this calculator determines the angle (in degrees) at which that maximum occurs. This angle is a critical indicator of vessel stability and safety.
Perform preliminary stability calculations during vessel design. Verify the angle at which GZ max occurs meets regulatory requirements.
Calculate stability parameters for new builds. Ensure vessels meet Notified Body standards.
Verify stability calculations during surveys and inspections. Generate documentation for certification.
Assess stability impacts of modifications or loading conditions. Support stability booklet preparation.
While this calculator provides the angle at which GZ max occurs, complete stability analysis requires professional naval architecture services.
