  Tyler and Tyson were awesome.  They even helped is get our large provisions order back to the marina with their boatyard truck. Diesel fuel was also easy at the separate fuel dock.  This marina gets a thumbs up

  Eric at Southport Marine who is not only super easy to contact. which included extremely quick response times and the ability to call at any time. Which is something that can not be said about every boat dealership. As the captain of my families boats and more of a eye for detail I was tasked with looking for out next boat. Being in my early 20’s many dealers or boat shows would even let me on the boat. Eric not only treated my twin in I with great respect, but also worked with us to comeuppance with a deal I have no regrets about. In all highly recommend South Port Marine and will be back for our next boat in a few years. Thanks Eric!
