We took the 12 person Diamante Viaggio Tri-Toon out for an evening on the river. Our group had a great time! We enjoyed the spacious boat with a great sound system, powered by an ultra quiet motor. Shawn was very helpful and provided an excellent experience for us.

We rented a camper from Shawn. Process was simple.which was nice because I’d never used a camper or hauled one before. Camper was clean. Worked out we got an extra day and a half out of the deal.

We purchased jet skis from Open Water Marine. Shawn and his team made the process easy! They educated us on them to ensure we knew how to take care of them and run them. Great service! Lots of memories to be made with our boys!
