• Model Patxi Areitio rents out seven boats on the boat-rental app GetMyBoat in Miami, Florida.
• During the summer, he can make up to $100,000 in revenue in a month, but there are also slow periods.
• Maintenance, gas, and labor costs and weather and client reliability also all cut into his revenue.

This as-told-to essay is based on a conversation with Patxi Areitio, a 34-year-old model and owner of a boat-rental business in Miami, Florida. Insider has verified his $100,000 revenue month with documentation. The following has been edited for length and clarity.
