Segment 1: Jacksonville to Fort George Inlet

Segment 3: Talbot Island State Park to Amelia River

  • Distance: Approximately 10 NM
  • Navigational Aids: The Amelia River is well-marked, but watch for depth variations, especially near the islands. The chart plotter will assist you, but it’s always prudent to keep a lookout for any breaking waves or birds, indicating shoals.

Segment 4: Amelia River to St. Mary’s

  • Shelter: As you approach St. Mary’s, consider the anchorage in the protected waters at St. Mary’s River. It's an excellent spot for shelter, especially if storm conditions arise.
  • Navigational Aids: The St. Mary’s entrance is marked with buoys—be cautious of the shoaling that can occur near the inlets. Check current weather conditions as wind can be a factor in this segment.
  • Points of Interest: Once you arrive in St. Mary’s, take some time to explore Crooked River State Park. The park features hiking trails and picnic areas, plus access to local wildlife.

Safety Precautions

  • Weather Monitoring: Always check local weather forecasts and conditions before departure. Sudden thunderstorms can occur, so be prepared to make adjustments.
  • Life Jackets: Ensure everyone onboard has access to life jackets. It's a legal requirement and a critical safety enhancement.
  • Communication: Ensuring a working VHF radio is imperative. Regularly check into local channels to stay updated on weather and navigational advisories.
