How high are fuel expenses for a weeklong Windtrip?

A Windtrip with a Catamaran or Monohull boat type is quite inexpensive in terms of fuel costs. With favourable wind the costs may not exceed 100€. In case of heavy use of the boat’s engines fuel costs can reach 300€ to 400€ depending on miles travelled, the boat’s mass and a fuel unit’s price at the given time. In case of a Motor Yacht fuel costs rise and can be calculated according to the particular boat’s manual.
