One thing that I have learned is that if you own a boat you will run into issues! We bought our boat new from Grace and love the boat! But as I said if you own a boat you will have issues from time to time. We have always brought our boat back to them for service. This last issue, come to find out was simply a dead secondary battery that controls our hydraulic steering. We dropped it off at the shop and Carl Jr. made a special trip in on a Saturday after hours to get our boat back up and running so that we would have it for the next day. Great group of guys!

These folks are just the best. Just purchased a used boat and they did everything to make sure she was sea worthy before i took off. Excellent service. Excellent advice. Great mechanics. Carl Jr, Mary and all the folks who keep this operation humming are top notch . Thanks.

I purchased a used 2007 Chapparal 210 from Grace Marine last weekend. Carl was above and beyond helpful. He responded to my emails and calls quickly before I'd ever stopped in. When I told him I was ready to come see the boat he had it ready and in the water when I showed up. Carl took the time to explain all the controls and any detail on the boat. I live abiut 4 hours away from Grace Marine and that evening I got a text from him asking if we made it home safe. Even though my boat cost less than 20k I felt like I got the same customer service of someone who bought the 138k Supra they had on the

Recently purchased a new Moomba Wakeboat from Grace Marine and could not be happier with the experience!!! Carl Jr. made the purchase easy and the whole team at Grace were a pleasure to work with! I purchased from out of state with a trade and Carl made the process smooth and easy! Will definitely look at Grace for any future purchases before anywhere else!!

Larry our salesman was outstanding! He never pushed us into any deal. He let us take our time to decide on the boat the we wanted.
Carl Jr. (owner) was the same way. He treated us very cordially and with respect. He let us know all of our options and which boat was the best buy for our budget. I highly recommend Grace Marine for your next boat purchase! A great family business!

Just bought a boat from this awesome dealer without seeing it in person. Great deal, the boat was amazing as advertised but there was one issue I would not have caught that they didn't either originally. They pointed it out and contacted someone in my hometown to fix it. Couldn't be happier with the boat, price and service. Awesome to find trustworthy people to do business with

I am one who never generally does reviews, but my family & I received outstanding customer service from Grace Marine so I felt compelled to share our great experience! Not once did we feel like all we were was a boat sale to them. Carl Jr. made us feel welcome and was genuinely wanting us to be happy with our purchase, not just making a profit! After many bad mechanical experiences with our last boat, saying that we were frustrated and stressed out would be an understatement! Carl Jr took our boat without even looking at what was wrong with it and gave us top dollar for trade, and then some! We
