The Grassy Key Marina is back online with lots of exciting changes and improvements.
We want to welcome Old Town Marine to Grassy Key. Based in Key West Old Town now offers on site services here on Grassy Key. Suzuki, Yamaha, Mercury, diesel, electronics and more. We also have partnered with Glass Monkey Fiberglass and Marine Coatings for any repair work you may need. Paint or gel coat repairs, gel coat restoration and much more.
You can rent a boat if you don’t have a boat thru our rental partners Paradise Watersports and if what you want is something a little slower speed: Kayaking The Keys is for you. Guided eco tours thru the mangroves of Grassy Key.
Here at the marina we offer affordable storage solutions for both boats and trailers. Inside rack storage in our newly configured barn or outside storage, boat ramp and lift services. New staff new attitude and lots of exciting new plans for the upcoming year. Stop in and see us and all that we have to offer.
