Calculation method

Calculation method

Vertical distance bow to bottom (m)

Rode=scope×(waterDepth+bowHeight).

Rode length at entered scope (m)

Rode=scope×(waterDepth+bowHeight).

Assumptions & limits

Assumptions & limits

  • Scope entered by user; no anchoring adequacy, bottom holding or wind recommendation. Supported limits: All required fields must be finite values of the exact declared type and within displayed bounds. Lists contain1–1000 finite numbers. JSON tables are numeric rectangular rows, at most100 rows and30 columns; individual tools have stricter shape/domain constraints. Scope entered by user; no anchoring adequacy, bottom holding or wind recommendation.
