As with most service-related industries, tipping is up to your discretion. It should be noted that for boat charters, tipping 10%-20% is customary.
While the boat captain is responsible for offering a safe and enjoyable ride, they are also providing an experience and a service to you. It's up to you as the customer to decide the amount you want to tip. In some cases owners may have a preferred tipping amount in their listing description.
