We would love for you to stay out and enjoy yourself! Say you reserved your rental for one hour. While you were paddling, you decided you wanted to paddle for another hour. You would just continue paddling for an hour, and once you return, we will charge you the difference. Within reason, of course. If extra time goes past sunset or overlaps with other reservations, we cannot allow an extension. We will tell you before we launch anyone if an extension is not an option.
