Black Oar Sup, Surf and Watersports Supply is pet-friendly. They offer local board brands for rent on the Minneapolis waterways. The Black Oar board Shop was founded by Alex Linnell, the first person to ever stand up paddle the entire length of the Mississippi River in the summer of 2011. Alex has set multiple world records including the Stand up paddle board distance record, paddling over 2323 miles in just 65 days. Boards are available for rent Thursday through Sunday from 11:00am to 6:30pm.
