  • Explain fuel, cooling, oil, batteries, belts, corrosion, ventilation, and recommissioning.
  • Apply winterisation to a realistic onboard situation.
  • Recall the core check: protect raw-water and closed-cooling systems correctly.

A self-guided revision companion that explains essential concepts, then helps you practise and test them. It supports—but does not replace—recognised instruction, practical training, assessment or certification. Access is a one-time payment, not a subscription.

What Layup Protects

Winterisation and layup protect the engine while it is unused. The main concerns are freezing, corrosion, stale or contaminated fuel, discharged batteries, damp electrics, perished belts and hoses, and missed service tasks.

The exact method depends on the engine, cooling system, climate, berth, and manufacturer instructions. Do not copy another boat's procedure without checking your own installation.

  • Protect raw-water and closed-cooling systems correctly.
  • Manage fuel contamination and tank condition.
  • Keep batteries charged and safe.
  • Service before layup or at recommissioning according to plan.
