There are a number of excellent boat marina shops on the island, this is one of our all time favorites. We boat out in the lower keys backcountry and make that cut through channel between Stock Island and Key West. This allows quick boating access to Garrison Marina from the Gulf or Atlantic. You have to idle slowly so you can get a good look at famous Sailboat Row, on your right as you boat into the harbor.
We have been stopping in for years, as I like taking the boat from here in the middle of the island. The harbor is all protected if you need to stop in for lunch, fuel, bait, or to get out of bad weather conditions and let it clear over. It is much easier renting a boat here than dealing with the hassle of bring it down.
If you need a boat tow call Key West harbor Services, as here you get professional and speedy service for help available on the water. The fleet of vessels is 24 hours a day ready to assist your needs. Most of the boat towing and marine assistance operations in the lower keys are handled by the Key West Harbor Services team. From Big Coppitt to the Dry Tortugas, 365 days a year.
For retail boating supplies you can go with West Marine or the Key West Marine Hardware Store. Both have all the goodies you may need for a boating day out to the reefs for some diving and fishing: Rod & Reel Combos - Boat Lights - Waterway Maps - Belts & Harnesses - Braid Line - Marine Batteries - Trailer Winches - Fishing Equipment - Marine Stereos - and you definitely need to use a Fish Finder down here in the Keys.
