Why We Love Miami

Miami is boaters’ heaven.  This is why we want to do everything we can to help you spend as much time as you can on the water—not waiting on boat repairs.  Miami has clear water and a warm boating season year-round.  There is no “off-season,” so we know it’s essential to keep your vessel ready to go all the time.

Miami has plenty of secure marinas with easy access to both the protected inland waters and the ocean.  Its location makes traveling down to the Keys, up the ICW, across to the Bahamas, toward the Caribbean, and even over to Mexico effortless. 

Therefore, it is no wonder that THE largest boat show in the world—the Miami Boat Show— takes place here.  Every year the show is magnificently orchestrated by organizations like the National Marine Manufacturers Association (NMMA) and draws yachts and visitors worldwide.

Miami makes everything from offshore fishing to picnicking on idyllic sandbars a delight for boat owners.  Our extensive waterways are lined with restaurants and bars boasting docks to tie your boat up to.  Even some of Miami’s best shopping locations can be reached by boat for the day.

Onyx would love to help you make the most of your time on the water.  If you need boat repairs in the Miami area—or would like to talk to us about any of our other services—we’d be delighted to hear from you.
