B07 – Propeller-Engine Matching & Ship Resistance
This course aims to take you from ship-resistance fundamentals through propeller hydrodynamics and Bp-δ propeller design to design-point and off-design propeller-engine matching, using worked numerical cases, NavCad examples and spreadsheet checks.

Course overview
Designed for: engineering graduates looking for refresher courses in niche expert areas.
Entry requirements: an engineering degree or equivalent experience, plus a working knowledge of fluid mechanics (Reynolds and Froude numbers) and basic ship geometry (hull form coefficients); familiarity with spreadsheets is helpful.
Learning format: self-paced online lessons with audio read-out, worked examples, a trawler case comparison and a NavCad case study, spreadsheet-auditing exercises, interactive tabs and flip cards, in-lesson checks, an AI tutor to answer questions as you go, and graded quizzes. This suits the aim because the course is calculation-heavy, so worked cases and checks after each idea build the judgement needed to choose a method and defend a matching point.
What you will learn
Explain ship-resistance components and the scaling laws used to extrapolate model results to full scale.
Compare major empirical ship-resistance prediction methods and judge when each method is valid.
Interpret open-water propeller characteristics from blade-element hydrodynamics and four-quadrant operation.
Apply the Bp-δ method to select propeller diameter, pitch, and related design parameters.
Determine design-point and off-design matching conditions between a propeller and a prime mover, including operational margins.
Work through numerical matching, installed-power estimation, and software/spreadsheet checks for marine propulsion problems.
