The calendar on this page is here so you can check if a Sea-Doo is available. The calendars are not interactive and are not used for booking a Sea-Doo. You can reserve a Sea-Doo on the Reservations page
If a Sea-Doo is available you will see "Sea-Doo Available" in the calendar. The calendar is updated with the customers name once a deposit is received and the Sea-Doo is booked. It is a very reliable way to check if a Sea-Doo is available.
