HOBA is a service that lets you Hop on a Boat anywhere. If you are the captain of your own boat, you can register to make money chartering passenger voyages in four categories: Fishing, Water Taxi, Harbor Tour, and Sunset Cruise.
The HOBA app checks your current location to find available captains in the area and then lets you book a trip. I came onto the project in late 2017 to help refactor the booking flow to match a new web service that was implemented on the server-side.
The app was written in Swift and is available for free in the App Store.
