Windjammer Wreck
261-foot iron wreck at 22ft depth—preserved by corrosion resistance. Thriving with coral and reef fish after 119 years.
Natural Attraction
A 261-foot iron-hulled ship rises from the seafloor at 22-foot depth, its three masts and two decks arranged in two wreckage fields 1,100 yards southwest of Loggerhead Key. The Avanti, wrecked January 22, 1907, while transporting lumber from Pensacola, resists corrosion far better than wooden vessels—its iron hull remains structurally sound over a century later. The wreck now functions as an artificial reef, hosting coral and reef fish. Divers and snorkelers must control buoyancy and avoid disturbing artifacts or fragile marine life.

Safety
- Safety Considerations
- Depth: 22 feet requires buoyancy control and diving experience. Wreck structures are fragile and sensitive to diver contact—poor buoyancy can damage the ship or injure marine life. Artifacts are protected cultural resources; removal and disturbance are prohibited by federal law. Ocean conditions subject to change; verify weather before diving. Nitrogen narcosis is a factor at this depth; assess your experience level and dive limits.

Planning advice
- Tips Advice
- Observe coral colonization on the hull—it shows how reefs reclaim wrecks over time
- Orient yourself to the distinct bow (east-west) and stern (north-south) sections to understand the wreck's final position
- Watch for sea turtles sheltering in structure; move slowly to avoid startling them
- Maintain neutral buoyancy throughout—less contact means better photos and safer diving
- Photograph the intact masts and deck structure—iron preservation after 119 years is rare and visually striking.

Frequently asked questions
Can I visit if I'm not a certified diver?
Yes, with snorkel access via a guide, but 22-foot depth is deep for snorkeling. Consult your operator about your swimming fitness. Most visitors use certified dive operators.
What makes this wreck special?
The Avanti is exceptionally preserved due to iron's corrosion resistance—wooden wrecks deteriorate much faster. At 261 feet, it's among the largest accessible wrecks in the region. Excellent coral and fish habitat has developed on the structure.
Can I take artifacts or souvenirs?
No. All artifacts are protected cultural resources. Removal and disturbance are prohibited by federal law. Leave them for scientists and future visitors to study and enjoy.
What do I need to bring?
Standard snorkel or diving gear. Reef-safe sunscreen is required—regular sunscreen damages coral ecosystems. Bring an underwater camera; the wreck preservation is spectacular.
How do I book a dive?
Contact authorized snorkel/dive operators. Ferry access to the park is via private ferry from Key West (separate fee from $15 park entrance). Children under 15 receive free park entry.
