A delivery fee is an amount equivalent to the cost involved in getting a yacht from its home port to the location where you intend to board. If the yacht is finishing a charter in a port which is a distance from the port where you intend to board, there may or may not be a delivery fee to pay. Much depends on the distance and time involved in positioning the yacht. Generally speaking, a delivery fee for a distance of up to 12 hours' cruising from the yacht's location is likely to be a "fuel-only charge". Thereafter, there may be some variations as to the charge, especially as there really is no standard delivery fee which applies -- it is all relative to the yacht, how much fuel it burns and how many crew members are on board.
