  • Lesson 3 • Tools and Workshop Practices

    Identifies hand tools, power tools, and measuring instruments used in marine environments. Proper storage and calibration practices prevent damage and ensure accuracy.

  • Lesson 4 • Vessel Anatomy and Systems Overview

    Introduces hull, deck, propulsion, and auxiliary systems as an integrated whole. Establishes the vocabulary needed for all subsequent maintenance tasks.

Chapter 2See details

Hull Inspection and Structural Maintenance

  • Lesson 1 • Structural Repair Techniques

    Covers welding, fiberglass lamination, and plate replacement for common hull damage. Repair methods are matched to hull material and damage severity.

  • Lesson 2 • Hull Inspection Methods

    Covers visual, ultrasonic, and hammer-test techniques for detecting hull defects. Systematic inspection routines reduce the risk of missed damage.

  • Lesson 3 • Drydock and Slipway Operations

    Explains blocking, shoring, and vessel positioning during out-of-water maintenance. Safe drydock procedures protect both the vessel and the maintenance crew.

  • Lesson 4 • Corrosion Identification and Control

    Explains galvanic, crevice, and pitting corrosion mechanisms specific to marine environments. Early identification and cathodic protection limit structural degradation.

  • Lesson 5 • Surface Preparation and Coating Application

    Details abrasive blasting, grinding, and chemical cleaning before paint application. Correct surface preparation is the primary factor in coating longevity.

Chapter 3See details

Marine Propulsion System Maintenance

  • Lesson 1 • Scheduled Engine Servicing

    Covers oil changes, filter replacement, belt and hose inspection, and valve clearance checks. Adherence to manufacturer intervals prevents premature engine failure.

  • Lesson 2 • Diesel Engine Fundamentals

    Reviews four-stroke diesel operation, fuel injection, and cooling circuits as a maintenance baseline. Understanding engine cycles guides correct service intervals.

  • Lesson 3 • Propeller Inspection and Repair

    Explains propeller pitch measurement, blade damage assessment, and underwater repair options. Propeller condition directly affects fuel efficiency and vessel speed.

  • Lesson 4 • Propeller Shaft and Stern Gear

    Addresses shaft alignment, cutlass bearing replacement, and stern tube seal maintenance. Misalignment causes vibration, bearing wear, and hull leakage.

  • Lesson 5 • Propulsion Fault Diagnosis

    Applies systematic fault-finding to overheating, excessive vibration, and power loss symptoms. Structured diagnosis reduces downtime and prevents secondary damage.

Chapter 4See details

Electrical and Electronic Systems Maintenance

  • Lesson 1 • Battery Systems and Charging

    Explains lead-acid, AGM, and lithium battery maintenance, testing, and charging management. Healthy battery banks ensure reliable engine starting and hotel loads.

  • Lesson 2 • Marine Electrical Safety Principles

    Covers DC and AC circuit fundamentals, insulation resistance testing, and shock hazard prevention. Marine environments amplify electrical risks due to moisture and salt.

  • Lesson 3 • Navigation Electronics Upkeep

    Covers GPS, radar, VHF radio, and chartplotter maintenance and antenna inspection. Reliable electronics are critical for safe navigation and distress communication.

  • Lesson 4 • Electrical Fault Finding

    Applies multimeter and clamp-meter techniques to locate open circuits, shorts, and voltage drops. Systematic testing minimizes diagnostic time and component damage.

  • Lesson 5 • Wiring, Panels, and Circuit Protection

    Addresses wire sizing, terminal crimping, panel inspection, and fuse or breaker maintenance. Correct wiring practices prevent overloads and onboard fires.

Chapter 5See details

Deck Machinery and Rigging Maintenance

  • Lesson 1 • Crane and Davit Inspection

    Explains wire rope inspection, sheave wear assessment, and hydraulic cylinder checks on cranes and davits. Load-bearing equipment requires documented periodic inspection.

  • Lesson 2 • Winch and Windlass Servicing

    Covers disassembly, gear inspection, pawl replacement, and lubrication of deck winches and windlasses. Regular servicing prevents catastrophic failure under mooring loads.

  • Lesson 3 • Mooring and Anchoring Equipment

    Covers chain locker inspection, anchor windlass maintenance, and mooring line condition assessment. Reliable anchoring and mooring equipment is essential for vessel security.

  • Lesson 4 • Standing and Running Rigging

    Addresses swage fitting inspection, turnbuckle adjustment, and running rigging wear on sailing vessels. Rigging failure at sea poses immediate life-safety risk.
