ust as in a restaurant or other service organization, yacht crew often count of tips as part of their annual income, and clients will pay a gratuity based on the quality of service. Industry standard is 10% to 20%, at the discretion of the charterer. You can either take the gratuity in cash or traveler’s checks and give it to the captain to distribute among the crew, or send the funds to Chamberlain Yachts in advance, and notify us when and how much you want released.
