The Complete Guide to Diving the USS Kittiwake Wreck

Few dive sites in the Caribbean capture the imagination of both beginners and seasoned divers quite like the USS Kittiwake. Resting on the seafloor just off Seven Mile Beach, this ex-US Navy rescue ship is one of Grand Cayman’s most iconic wrecks - and an absolute must-dive for visitors to the island.

Whether you’re a wreck enthusiast or a first-timer, this guide will give you everything you need to know about diving the Kittiwake - from history and structure to safety tips and marine life encounters.

A Quick History of the Kittiwake

Commissioned in 1945, the USS Kittiwake (ASR-13) served as a submarine rescue and support vessel for over 50 years.

Highlights of her service:

• Supported the recovery of the black box from TWA Flight 800

• Played roles in Cold War submarine operations

• Decommissioned in 1994

In 2011, the Kittiwake was intentionally sunk as an artificial reef and dive attraction - resting upright in about 65 feet of water off the west coast of Grand Cayman.

Location & Conditions

📍 Location: West side of Grand Cayman 🚤 Access: By boat, ~10 minutes from the dock 🌊 Conditions: Usually calm, excellent visibility (70–100 ft) 🌡️ Water Temp: 78–84°F year-round

This makes it perfect for:
