Certification Requirements: The document outlines the need for vessel,
propeller, and nozzle certification, specifying options such as ABS, Lloyds, DNV, or others. It distinguishes between open propeller applications and those requiring a nozzle, with additional sections for nozzle applications.
Vessel Information: Key details required include manufacturer, model, year, and intended use (work/commercial, towing, pleasure). Hull type options are displacement, semi-displacement, and planing, with bottom design choices of open, tunnel, or pocket. Hull materials can be fiberglass, wood, or aluminum.
Engine Data: Comprehensive engine data is mandatory, including manufacturer, model, year, maximum engine rating (Brake HP or Shaft HP at RPM), gear reduction ratio, fuel type (gas, diesel, other), and the number of engines (single, twin, triple, other). Current performance metrics such as full throttle engine RPM and vessel speed (MPH or knots) are also required.
Propeller Data: Information on the current propeller includes manufacturer, model/style, material (bronze, nibral, stainless steel), size (diameter x pitch), number of blades, and rotation direction. Maximum propeller diameter or shaft to hull distance must be specified.
Re-power Data: For re-powering, old engine information is needed, including manufacturer, model, year, maximum engine rating, gear reduction ratio, fuel type, and number of engines. Old performance data such as full throttle engine RPM and vessel speed is also required.
Additional Notes: The accuracy of propeller suggestions depends on the completeness and accuracy of the provided information. The document includes a section for additional comments and dimensions.
