Why Boaters Choose Erwin

I purchased a boat from Erwin Marina 2 weeks ago. This organization is top notch. I have my boat at their gold point marine. Brian and Melanie have gone out of their way to make me and my wife feel at home. They had my boat cleaned, put a new name on it. The dock and the area around the marina is very nicely done (like a resort). They also have a parts department on site. I could go on an on about how nice everything is. Take you for allow us to join the Erwin family.

What a great experience purchasing a beautiful used Cobalt. We live a couple hours from Erwin and so started our experience with Payton on the phone. He was great AND when he needed to research something he gave me a call back within 5 minutes. Drove down and Payton was very knowledgeable showing us around the boat. He was very responsive throughout the contract and inspection process, and he personally accompanied the delivery driver up so that he could help me bring it into our lift for the first time. Overall, just a great experience and we were thoroughly impressed.

I take my tri-toon here for service or to purchase parts. Always great service. The mechanic that worked on my boat was very informative. Kelly saved the day a few weeks ago when my son-in-law took my boat out on a Saturday and it wouldn’t start. He had them bring it by, they trouble shot it, fixed it asap, and they got to enjoy the day on the lake!
