We guarantee that your reserved boat will be there, and as such, if one isn’t returned on time, we’ve got a problem for the next person, particularly on sold out weekends. If your boat isn’t returned on the date we’re expecting it back and we’ve all left for the night, an extra day will be charged to your reservation at the single day rental rate. If you’re just getting back at 7pm instead of 6pm, you’ll probably be fine.
