INSIGHT

Think Like A Seaman First

  • New tech like lithium and automated sail systems must be judged from a seamanlike perspective, not gadget lust.
  • John Harries urges assessing whether technology truly improves safety and seamanship before adopting it.
ANECDOTE

Early Roller-Furler Near-Disaster

  • John sailed his first ocean passage on an early Hood roller furler and called it a nightmare that nearly caused a disaster.
  • He now uses roller furlers for jibs for 38 years but warns they must be treated carefully.
ADVICE

Use Communicative Battery Management

  • Avoid lithium batteries whose BMS cannot communicate with charging sources because they can cause sudden blackouts.
  • Use batteries with external or communicative BMS so chargers know when to stop and prevent failures.
