19th Century Wooden Sailing Vessel
Basalt ballast and iron rigging mark a 19th-century wreck in Biscayne's reef waters.
Natural Attraction
Stone ballast and iron fastenings scattered across the seafloor reveal a small to medium-sized sailing vessel from the 19th century. The rigging elements and wooden structural remains suggest a working merchant ship, though her origin and fate remain unknown. Most of her cargo was salvaged after sinking, leaving only ballast and structural debris as archaeological evidence.

Planning advice
- Insider Tips
- The basalt ballast is not a shipping signature—ballast was commonly offloaded and reshuffled between vessels for ongoing voyages.
- Examine rigging elements and iron fasteners closely; they reveal 19th-century maritime construction.
- Most cargo vanished centuries ago; focus on structural details and ballast heap geometry.
- Afternoon seas rougher than morning; early departure maximizes safe bottom time.
- This site rewards maritime history curiosity more than visual drama.
- Tips Advice
- The basalt ballast was moved between ships as ballast cargo—it reveals nothing definitive about her origin or last port.
- Look for the largest stone piles marking the ship's keel area; these anchor the site.
- Rigging elements are fragile; observe but do not touch—protected archaeological site.
- Plan boat departure early morning; afternoon seas rougher and visibility lower.
- Wreck is largely salvaged; expect subtle details and stone piles, not hulking timbers.

The experience appeals primarily to maritime archaeology enthusiasts and diving-savvy travelers.
Location
Frequently asked questions
Do I need SCUBA certification to see the wreck?
Snorkeling can reveal surface ballast piles; full wreck appreciation requires SCUBA certification due to depth (20-50+ feet) and currents.
Can non-swimmers or casual snorkelers visit?
No. You must be a confident swimmer at minimum for snorkeling access to ballast. Deeper sections require SCUBA certification.
Can I collect or remove artifacts?
No. This is a protected archaeological site. Federal law prohibits artifact removal. Observation only.
Is it worth the boat trip for a mostly salvaged wreck?
If you're interested in maritime archaeology and 19th-century trade routes revealed by ballast composition, yes. Otherwise, more visually dramatic wrecks exist in Biscayne.
What if water conditions are rough or I get seasick?
Winter (December-April) offers calmest seas. Summer and fall carry hurricane risk. Always check marine forecasts; rough water days are common offshore.
