    Planing craft resistance prediction for Windows

PropCalculator is a free online propeller size calculator. With propCalculator you can estimate the size (Diameter and Pitch) of your propeller. It works with single or twin engine boats capable of achieving semi-planing or planing speeds (up to approx. 35 knots) Key features Estimate the performance of your semi-planing or planing boat Estimate the size of your propeller (works with single or twin engine boats) Adjust required pitch for different propeller diameters Results in metric or imperial units PropCalculator provides only estimations of your boat’s performance and propeller diameter/pitch based on estimation methods. For more accurate results regarding your boat’s performance use quickPlaning for Windows or planingRhino forRead More →

 quickPlaning  for Windows is a new easy-to-use Windows desktop application for planing craft resistance prediction. Too often the designer or naval architect is required to predict the performance of a new or existing design, sometimes at the earliest design stage or with little available data. Total speed at various load conditions, total engine power, or running trim angle at service speed, are properties needed for future design decisions such as final dimensions or further design optimization, scantlings, re-power options, etc. quickPlaning uses the Savitsky’s method (with some modifications to include air resistance and resistance correction at semi-planing speeds) to provide quick answers to your performance relatedRead More →

 planingRhino is a new easy-to-use Rhino plug-in for planing craft resistance prediction. With planingRhino you can estimate the performance of your new or existing hull design by either reading geometry parameters directly from your 3D model or evaluating a hull from user provided data. Key features Evaluate hull design up to ten (10) speeds Estimate running trim angle Estimate aerodynamic resistance Estimate bare hull resistance and total resistance Define propulsion efficiency, resistance margin and estimate total required power View graphs (speed vs running trim and speed vs resistance) Export results in .cvs format for further process or reporting Read more about planingRhino features or download a 20-day freeRead More →
