Since Boatsetter is a community that aims to provide the best user experience, it is important to make sure your calendar is up-to-date. Renters rely on your calendar to know your boat's availability and rates. To change the availability of your boat, just click My Boats > Manage > Calendar (pictured below).
Next, just adjust the specific dates on the calendar you wish to change. You will be prompted to change the "Status" of the date to "Available" or "Unavailable" (pictured below). Additionally, you can change the price of that specific day.
