Operating expenses.
These vary depending on the area you cruise and the yacht you choose.  If fuel economy is important, discuss this with your broker at the beginning of your selection process.  There also may be some harbor fees and positioning (delivery) charges if your charter involves meeting or leaving the yacht in a place other than it's home port.

Harbor Fees.
Often called dues in Europe, these vary from port to port.  Normally this is a small item in the charter budget, especially in the Caribbean or Pacific Northwest.

Gratuities.
Tipping yacht crews is both customary and discretionary.  The standard practice is to award 10 - 20% of the charter fee, based on you level of satisfaction, at the close of the charter.  It is customary for the charter party to leave the entire gratuity with the captain with suggestion as to how the gratuity should be distributed among the crew.

Deposits
Once you select a yacht, dates and location, your broker will provide you with a charter contract.  When you approve the contract, you will be asked to provide a deposit - usually 50% of the charter fee.  If it is a WMT - type charter, your expenses will be estimated for the purposes of the deposit.  Usually the balance is due 30 in advance of the charter.
