Navigating Riviera Beach Channel Markers: A Local's Guide

Understanding Riviera Beach's Channel Marker System

Riviera Beach sits at one of Florida's most navigationally complex intersections where Lake Worth Inlet meets the Intracoastal Waterway. This convergence creates a challenging maze of channel markers that confuses even experienced boaters. Add strong currents, shifting sandbars, and heavy boat traffic, and you have a recipe for navigation disasters.

This local's guide decodes Riviera Beach's channel marker system, providing turn-by-turn navigation through the inlet, around Peanut Island, and along the ICW. We'll reveal the unmarked hazards, explain confusing marker sequences, and share insider knowledge that charts don't show.

Lake Worth Inlet: The Critical Navigation Challenge

Understanding the Inlet Configuration

Lake Worth Inlet serves as the primary ocean access for thousands of boats from Palm Beach to Jupiter. The inlet features:

• Width: 400-500 feet
• Depth: 12-35 feet (variable)
• Current: Up to 5 knots
• Traffic: 500+ boats on weekends
• Hazards: Shifting shoals, breaking waves

The Marker Sequence Explained

Approaching from Ocean (Eastbound):

1. Sea Buoy "LW" (Flashing White)

   • Located 0.5 miles offshore
   • Marks safe approach angle
   • Stay north in good weather
   • South in strong north wind

2. Entrance Markers R2/G1

   • Red right returning
   • Channel narrows here
   • Watch for outbound traffic
   • Currents strongest

3. Inner Markers R4/G3

   • Channel turns slightly north
   • Shoal south side
   • Stay mid-channel
   • Speed restrictions begin

Critical Local Knowledge:

• North side shoals extend further than marked
• South jetty creates eddy on incoming tide
• Breaking waves indicate shallow water
• Commercial traffic has priority

Inlet Timing Strategy

Best Conditions:

• Slack tide (easiest)
• Incoming tide (safer)
• Early morning (calmest)
• Weekday (less traffic)

Avoid:

• Outgoing tide + east wind
• Weekend afternoons
• Storm conditions
• Night passages (if possible)

Peanut Island Navigation

The Confusing Marker Array

Peanut Island's popularity creates unique navigation challenges with multiple approach channels and anchorage areas.

Main Approaches:

1. North Channel (Deepest)

• Markers: R8, R10, G7, G9
• Depth: 10-15 feet
• Width: 150 feet
• Best for: Larger boats

2. South Channel (Popular)

• Markers: R12, R14, G11
• Depth: 6-10 feet
• Hazard: Shoals both sides
• Best for: Small boats

3. West Cut (Locals Only)

• Unmarked channel
• Local knowledge required
• 4-6 feet depth
• Shortcuts to anchorage

Anchorage Navigation

Designated Areas:

• North anchorage: Deep, current
• East anchorage: Popular, crowded
• South anchorage: Shallow, protected
• West prohibited: Coast Guard

Marker Guidance:

• White buoys: Anchorage boundaries
• Yellow buoys: Swim areas
• Orange markers: No anchor zones
• Private markers: Ignore

Hidden Hazards Around Peanut Island

Unmarked Dangers:

1. Northwest Shoal

   • Extends 200 yards
   • 2-3 feet at low tide
   • Many groundings
   • Avoid completely

2. Southeast Bar

   • Shifting constantly
   • Breaks in swells
   • Extends from island
   • Use deep channel

3. Old Pilings

   • West side remnants
   • Just below surface
   • Not marked
   • Historical structure

ICW Intersection Navigation

Where Three Waterways Meet

The confluence of Lake Worth Inlet, ICW, and Lake Worth creates complex currents and traffic patterns.

Key Intersection Markers:

ICW Markers:

• R36 northbound
• G35 northbound
• R38 southbound
• G37 southbound

Turning Points:

• Inlet to ICW north: Hard right at R36
• ICW south to inlet: Left at G35
• ICW north to inlet: Right at R38
• Complicated by current

Right-of-Way Complexities

Priority Order:

1. Commercial vessels
2. Vessels restricted by draft
3. Vessels exiting inlet
4. ICW through traffic
5. Recreational boats

Common Conflicts:

• ICW crossers vs inlet traffic
• Sailboats vs powerboats
• Fishing boats anchored
• Tour boats stopping
