Here is a little more lagniappe for you....

"How much should a charterer give. We say, for The Caribbean, the range is 10 to 20 percent of the charter fee. If the charter fee does not include meals, the tip should be based on just the boat fee.

If you felt the crew had done a good job, 15% is a good tip - by giving 10%, you are telling the crew that things were OK but not perfect."

"Tipping Etiquette?" "All tips should be given directly to the captain so that he can divide the amount out between all the crew."
