The basic daily rental is structured as either a quarter-, half-, or full-day. A quarter-day is two hours, a half-day is four hours, and a full-day is eight hours. You can also discuss a custom trip with the boat by contacting the owner through Sailo.
Most term charters (weekly rentals) are from Saturday to Saturday. Keep in mind that the boat generally needs to be back at the dock by Friday evening, and you will need to be off the boat on Saturday morning so they can prepare the boat for the next guests.
