Great improvements to the Marina with new owner…the recently remodeled store has great inventory…..a quick alternative if you don’t want to drive into Marathon….staff has always been professional and accommodating….. Stacey is a true gem and keeps things running smoothly!

One-stop-shop for all things getting out on the water. Boat storage, groceries, beers, bait…….all much better priced than anywhere in Marathon or Duck Key. New ownership has brought on strong staff with a numerous enhancements to the marina and boatel storage. Access to the staff for scheduling is always 24/7 and operating hours of 7am- 7pm are super helpful coming & going to our house on Duck Key.

I've had my boat here for about a year now. New ownership has had a few growing pains but the last 4 months have been great. Jared is awesome regarding anything for the boat/barn/yard. Extremely accommodating. My boat always gets pulled and dropped in fast. Heidi is very helpful in the store and Stacy is always helpful coordinating. It's also gated overnight so I feel like my equipment is safe.

These people are crooks and nothing more. I paid them ($600) for a 20-hour service. It was never done. I paid the $75 to mount my EPERB on my boat, It was never done. I paid them $200 to put my cover on my boat. It was done so incorrectly that my boat filled with water and flattened all 4 of my tires. The owner is a lawyer and is the normal asshole lawyer. If you do business with these people, you need to beware. They are going to steal your money!

I stored my boat at the marina for 6 weeks. The storage was fine and the boat was just as I left it. I was supposed to pick up the boat on March 18th after arriving from our flight in Miami. The flight was delayed and traffic was bad so I was not able to pick up the boat before closing. The plan was to get it the next morning. The next morning saw thunderstorms roll thru all morning. I called them and told them I would be in that afternoon after the storms. When I got there some guy with a major attitude brought the boat around and told me that because I did not get there until 3 pm that would owe for 2 days. I was not a math major in college, but at the worst it seems like I owed for one day. So when was the mysterious check out time on Saturday? Even then, really? Hope you put the extra $50 to good use as I will never be back.

Great service from dock master , store staff very helpful , the bait is some of the best ever and good value for money, this place will turn in to something very special,

Good location, ramp is easy to use with a steep grade, fresh water hoses every where, the shop has plenty of provisions, good rates for everything. They don’t call it grassy key for no reason though! With west winds there can be a lot of weeds at the launch. Knowing how to clear your intakes on PWC’s will make your trip much easier.

My boat and trailer were ready when promised and I will be using their storage facility again. Good value for the money.

Bill & staff were awesome. Great ramp, single ramp that is protected and nice & steep for an easy load & unload. Store is clean and stocked and everyone on staff was so friendly. Thanks for keeping our trailer during our trip and being so hospitable.

My boat was safe and easy to leave and pick up

The marina was extremely easy to get in and out of. We rented a slip for one week and really enjoyed it! In addition when we had a problem with our boat Billy came over right away to help and even found a mechanic to help us the very next day. We also had three rowdy kids with us who everyone was very kind to!I would definitely use this marina again. Five stars all the way!

Friendly and professional. Great prices.

by Steven C. - Verified user on Aug 11, 2021

Facilities and staff were great. Marina closes and gates locked at 7pm with no access in or out after that, very inconvenient.

by Mark J. - Verified user on Dec 31, 2020

The marina staff looked over our skiff for a year. Circumstances led me to leave tools, coolers, tires and other valuable items in the boat. Everything was exactly as I left it. They were even kind enough to send pictures of my boat to keep me happy. I would highly recommend this facility.

It was easy and nice to stay at Grassy Key Marina.... The place is clean and now I must say the store has everything we need. Thanks.
