What Our Clients Say About Us

    
 
 
       
   Zac Bongiorno 
 
 
  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!

  My experience buying a boat and the service from Mike Samoisette at South Port Marine was bar none one of the best experiences I could have hoped for.  Mike (and all at the marina) went above and beyond to help educate me about boat buying/ownership/maintenance etc.  Mike and his team pulled off a very tight timeline for delivery of the boat and made sure it was done in the most professional manner.  Many thanks to Mike and South Port Marine for a wonderful experience around this big occasion for me.

  Stay with South Port Marine. Great staff, good prices, well stocked dock shop, quick walk to restaurants, cafe's grocery, ATMs, and pharmacy. We docked through Dockwa with a 38' sloop. Coming and going was a breeze, deck hands were always around, channel is clearly marked. Mandy the dock master and her staff were gems. We'll be back.
