[For my story of Days 1 through 3 along a section of the Intracoastal Waterway (ICW), go here.]
Day 4: Left Alligator Pass about 2 hrs. before high tide in Fernandina Beach, 10 miles further north. Had trouble finding deep enough water on 1st try; 2d try was able to re-enter ICW and continue north. Would have had trouble leaving anchorage on any but the highest half of the tide cycle. Briefly lost ICW channel south of Amelia Island bridges due to numerous crab floats in area. Briefly grounded hard as we approached the final turn into deep water south of Fernandina Beach; re-floated after 2 minutes of hard-over rudder, full reverse, spinning & twisting to break free.
Took a mooring buoy at Fernandina City Marina, dinghied ashore, saw sights. Fort Clinch is fun for fort fans. There's a dive bar along the main drag of Fernandina Beach a couple blocks up from the marina, that anyone who has ever been to Port Townsend, Washington, will recognize as the Southern twin of the Town Tavern. Including the heavy cigarette smoke and the hairiness of the bartending staff.
Later pulled dinghy out of low-tide mud (you know a dock is in shallow water when your dinghy ends up aground). Returned to The Fox - onshore action is big fun but mooring field is between 2 pulp mills, which: stinky, bright and noisy. Use earplugs and - when the wind blows right - extra asthma inhalers.
