Tips - Plan your ride timing:

  • To align with required check-in times for your ferry.
  • To minimise the ferry crossing time.
  • If you were to allow as much as 5.5 hours for the ferry crossing, this ride would require a overall average of 87km/h during the remaining hours. - You do not have to speed to complete this certificate.
  • Your timing will need to be highly accurate and you will require very efficient stops.
  • This is a challenge of planning and execution.
