Comprehensive site assessment for tension-leg seastead platforms in the Caribbean region. Evaluating territorial, EEZ, and international water options within depth constraints.
Within 2,000 miles of Anguilla, there are no international water locations (beyond 200nm from any nation) that meet your depth requirement of less than 100 feet. The Caribbean Sea is entirely partitioned among nations' EEZs, and the surrounding Atlantic areas beyond EEZs have depths of 3,000-15,000 feet. All shallow, sandy-bottom areas are within national jurisdictions.
5 excellent sites identified behind offshore islands with sandy bottoms at suitable depths.
RecommendedExtended sites within Anguilla's EEZ but beyond 12nm territorial waters offer more seclusion.
FeasibleNo suitable shallow sites exist in international waters within 2,000 miles of Anguilla.
Not AvailableThese locations are within 12 nautical miles of Anguilla's coastline, hidden from main island view by offshore islands. All feature sandy bottoms suitable for mooring screw installation at depths within your 100-foot constraint.

Located on the western (leeward) side of Dog Island, completely hidden from Anguilla's main island by Dog Island itself. Protected from prevailing easterly trade winds. Sandy bottom with patch reef areas to avoid.

Northern exposure of Scrub Island provides excellent hiding from main island views. Some wave exposure from Atlantic swells but manageable. Multiple sandy patches between coral heads.

West of Prickly Pear Cays, excellent protection from easterly trade winds. Popular boating area on weekends, but weekday privacy is excellent. Marine park considerations apply.

South of Anguilla, hidden by the island's southern coast. Protected channel between Seal Island and main island. Shallower depths make installation easier, but closer to boat traffic.

True over-the-horizon location. At 32 nautical miles, this site is beyond the visible horizon from any point on Anguilla's main island. Sombrero Island provides some wave shelter. Deeper waters may approach your 100ft installation limit. Exposed to Atlantic conditions.
Note: More exposed to Atlantic weather systems. Higher wave heights require robust tension-leg engineering. Depth approaches installation limit - detailed survey required.

A thorough search for international water locations (beyond 200nm from any nation's coast) within 2,000 miles of Anguilla that could support shallow-water seasteading.
Your Limit: 100 ft
No areas this shallow beyond EEZs
Continental shelves and shallow banks are always within 200nm of land. The ocean floor drops steeply beyond the shelf break. In the Caribbean region, all shallow areas (<100ft) are coral banks, island shelves, or coastal zones—all claimed by nations.
The Caribbean is entirely covered by EEZs: Anguilla (UK), St. Martin (France), Saba/St. Eustatius (Netherlands), St. Kitts & Nevis, Antigua & Barbuda, and others. No "gaps" exist where international waters reach shallow depths.
| Region/Feature | Jurisdiction | Depth | Distance | Status |

| Anguilla Bank | UK (Anguilla) | 30-100 ft | 0-15 nm | Available |
| Saba Bank | Netherlands | 40-150 ft | 120 nm SE | EEZ |
| Pedro Bank | Jamaica | 50-150 ft | 900 nm W | EEZ |

| Bahamas Banks | Bahamas | 10-50 ft | 600 nm NW | EEZ |
| Mid-Atlantic Ridge | International | 8,000+ ft | 1,800 nm E | Too Deep |
| Open Atlantic (>200nm) | International | 12,000-18,000 ft | 200+ nm | Too Deep |
Begin with Site A (Dog Island West) for initial prototype. Closest to support infrastructure, excellent protection, sandy bottom.
Conduct detailed bathymetric survey of proposed 500ft grid area before final positioning.
Engage with Anguilla Maritime Affairs for permitting. Your research/testing status may facilitate approvals.
Once proven, expand to Site E (Sombrero) for true isolation and over-the-horizon positioning.
Consider Saba Bank (Netherlands EEZ) for larger-scale community—120nm SE, extensive shallow area.
For international waters, consider deep-water spar or semi-submersible designs instead of tension-leg platforms.
You have excellent options within Anguilla's jurisdiction that meet all your technical requirements. The territorial and EEZ sites offer sandy bottoms, suitable depths, and natural visual barriers. International waters with shallow depths simply don't exist in this region—this is a geographical reality that no engineering can overcome. Focus your efforts on working with Anguilla authorities and, if needed, exploring other nations' EEZs through bilateral agreements.
