GoMarina is a free Android app that allows you to pay port fees and other products and services in guest harbors effortlessly. The app requires a one-time password via SMS for registration, which is a quick and easy process. Once registered, you can add information and a photo of your boat to ensure that your purchases are associated with your boat.

The app allows you to pay via credit cards, and you only have to enter your credit card information once. All future charges will be made through the same card. It is essential to note that the app does not store any credit card information. Instead, the payment provider stores the data as per their guidelines for privacy and security.
