Key West by Sea: The Southernmost Charter

The Overseas Highway is one hundred and thirteen miles of bridges and brake lights, and every one of them was built beside water that is doing something better. Chartering to Key West puts the road where it belongs: in the background, a thin grey line off the starboard side.

This is the log of a three-day run our crews make from March through May, when the trade winds settle and the water on the reef clears to sixty feet of visibility. Distances are honest, times are typical, and the boat is a 70-foot motor yacht with three cabins, which is the right size for six people and a great many towels.

Government Cut, then the long southern reach

Out through the cut, past Fisher Island, and a hard right into the southern half of Biscayne Bay. Stiltsville slides by to port, Elliott Key to starboard, and by ten the water south of the Featherbed Bank turns from green to gin. Card Sound and the top of Key Largo mark the moment the Keys begin in earnest. Coffee on the flybridge; nobody is in a hurry.

Hawk Channel, inside the reef

Once through Angelfish Creek the route settles into Hawk Channel, the protected lane between the islands and the reef line. Five to eight miles wide, twenty feet deep, and calm when the Atlantic beyond the reef is not. The lights tick past: Carysfort, Molasses, then Alligator Reef off Islamorada, where the lighthouse stands on a shelf of coral and the parrotfish outnumber the people. Lunch underway, then an hour in the water there.

Marathon, the honest halfway

Marathon sits about ninety nautical miles from Miami and is the practical overnight: fuel, a proper marina at Boot Key Harbor, and a sunset that clears the Seven Mile Bridge to the west. Dinner is stone crab while the season lasts (October to the start of May) at one of the dockside places, then back aboard. The first night in the Keys is when the group's phones stop mattering.

Sombrero Reef, then under the bridge

The morning belongs to Sombrero Key, four miles off Marathon, a shallow spur-and-groove reef with a lighthouse and brain coral the size of small cars. An hour of snorkeling in seventy-eight degree water, then the captain threads the Seven Mile Bridge, where the old span and the new run side by side and the boat feels briefly like it is passing through a cathedral.

Bahia Honda and Looe Key

West of the bridge the Lower Keys begin, and Bahia Honda's beach is the best in the chain. Anchor off the old railroad trestle, swim ashore for a walk, then run seven miles offshore to Looe Key, a sanctuary reef with the densest fish life between here and the Bahamas. This is the trip's centerpiece; the crew plans lunch around it.

Key West, arriving with the sun

Forty-five nautical miles from Marathon, and the last hour is the approach past Stock Island into Key West Bight, timed for the hour when Mallory Square does its nightly performance. From the water the sunset celebration looks like what it is: a town that decided long ago to applaud the end of the day. Berth at the Bight, walk to Duval Street, or do not.

Key West, and the long view west

Morning coffee facing Sunset Key. Guests with a full week add the Dry Tortugas, seventy miles further west, where Fort Jefferson rises out of water so clear the moat looks painted; it is a long day by yacht and a very good one. On a three-day plan, the morning is for the town's quieter corners: the Hemingway House cats, the Truman Annex, a slow tender ride along the harbor.

The return, or the flight

Here the log forks. Guests with time run back the way they came, two easy days with different reef stops. Guests without it fly from Key West's small airport, under an hour to Miami, and the yacht makes the delivery run home with the crew. Both are legitimate. The second is why a one-way charter to the end of the road has become the most requested spring itinerary we run.

One hundred and thirty nautical miles, three days, one road you never had to drive. Explore the fleet and ask which yachts run the Keys in spring.
