propCalculator

Boat owners, engine vendors or yards can use our propeller calculator application, propCalc,  to estimate the performance of a planing boat, choose the right diameter and pitch of the propeller or evaluate the existing setup. propCalc is easy to use and requires no installation as well as minimum user input. It is the ideal practical tool for quick performance evaluation of new or existing boats, propeller sizing, and re-powering.

propCalc runs within most web browsers allowing you to use it with almost any platform. It requires minimum user input as it applies a simple but practical method to estimate a boat’s performance and its propeller size. propCalc can help you:

  • Estimate a planing or fast semi-planing maximum speed
  • Determine the diameter and pitch of its propeller(s)
  • Produce running data for the whole range of engine rpm including: boat speed, power delivered to shaft and fuel consumption
  • User can provide existing propeller performance data. In this case propCalc will estimate running data for the existing propeller for comparison
  • Produce power curves for the engine, the proposed propeller and the existing propeller
  • Print the output or save it as pdf file

Weight Estimation

When the details of a boat are unknown, boat owners, engine vendors or yards can use our weight estimation application,  to estimate the boat’s light craft and total mass.  It is the ideal practical tool for quick estimation of a boat’s weight for quick performance evaluation of existing boats. Additionally designers and naval architects can use the weight estimation application to roughly estimate a boat’s mass at design proposal or preliminaly design stage.

Weight estimation application runs within most web browsers allowing you to use it with almost any platform. It requires minimum user input and suggests typical values when boat parameters are unknown.

  • Roughly estimate a boat’s mass
  • Include weights of structural, electrical, components, machinery, tanks, etc
  • Based on volumetric mass coefficients
  • Print the output or save it as pdf file

quickPlaning v1.1

New version 1.1
 quickPlaning  for Windows is a new easy-to-use Windows desktop application for planing craft resistance prediction and propulsion analysis

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 related questions.

With quickPlaning you can estimate the performance of your new or existing hull design  as well as size or evaluate your boat’s propeller(s).

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
  • Estimate sizing parameters of boat’s optimum propeller(s) for given load condition and engine characteristics using GAWN propeller series and cavitation criteria.
  • Evaluate existing propeller(s) for given load condition and engine characteristics

Ideal for boat & yacht designers, naval architects, marine surveyors, and marine engine vendors, who require an easy-to-use, quick resistance/power prediction software tool for planing crafts.
