With GetMyBoat, you can tip in advance of your trip date as part of the booking process. It's a separate line item from your rental and it's completely optional. For boat charters, tipping 10-20 percent is customary. While the boat captain is responsible for offering a safe ride and navigating the waters with ease, he or she is also providing an experience and a service to you.
GetMyBoat does not deduct its fees from the tip.
