Nautical Distance from Port O'Connor, TX to Cozumel, Mexico

There is no direct nautical route between Port O'Connor, Texas, and Cozumel, Mexico.

Geography

• Port O'Connor sits on Espiritu Santo Bay, part of the Texas Gulf Coast (northwestern Gulf of Mexico).
• Cozumel is an island off the Yucatán Peninsula in the Caribbean Sea.

The Water Path

A vessel would need to transit:

1. Gulf of Mexico (west to east) ~600 nm.
2. Through the Yucatán Channel (between Cuba & Cancún) – ~100 nm wide, strong current (Loop Current / Yucatán Current).
3. Into Caribbean Sea, then south to Cozumel ~50 nm.

Total approximate rhumb line distance: ~750 nautical miles. But this is open-ocean passage, not a standard "nautical mile distance" like a coastal hop. It requires offshore capability, weather routing, and clearance (Mexico/US/Cuba EEZs).

No scheduled ferry or commercial service exists. Private yachts make the crossing (typically 3–5 days).
