About Key West Cut A Range Rear Lighthouse

The Key West Cut A Range Rear light is a skeletal tower standing 10 meters tall, with its light positioned 21 meters above the water. This structure, supported by piles on a platform, guides vessels on a northwest reach along the main channel. It emits an isophase white light, meaning a steady white light followed by a period of darkness, completing a cycle every 6 seconds. The light has a geographic range of 13.4 nautical miles. The operational site is accessible by boat, but the tower itself is closed to the public. It is located about 2.5 kilometers west of the Key West waterfront.

Why it matters: This rear range light, paired with a front light, provides mariners with an exact line of travel, which is indispensable for safe navigation into and out of Key West along the critical northwest reach of the main channel.
