Yes, you will take over your boat fully fuelled. In most cases there will be plenty of fuel for your holiday. Occasionally, such as on an extended holiday, you may need to refill during your holiday, and you will be advised about this situation at the start of your holiday. If this is the case, you will be asked to obtain a receipt and the boat yard will refund you the cost on your return at the end of the holiday.
Will there be enough fuel on the narrow boat?
