    We had a great time on our pontoon boat. The boat was in great shape and ideal for a day on the water. Communications with Erwin were easy and clear - Jody was in touch with us before and during our rental to make sure everything was going well.

    Jody and the whole Erwin crew are always so great to work with! Great communication and always easy to get in touch with. This was my fourth time renting from them and my group had a blast. Can’t wait to be back on the water again.

    Amazing experience with our family Pontoon rental. We booked last minute and Jody hooked it up with the larger boat upgrade. We had a beautiful afternoon cruising the lake and jumping the cliffs. Totally recommend! No wonder they are all word of mouth recommendations.

    Absolutely outstanding. Pricing was surprisingly inexpensive, the service was great, the convenience and ease of navigation out of the marina was impeccable. I will 100% be renting again in the future
