Precision for Intricate Coastal Navigation

The Broken Group is a world-class destination for recreational boaters, kayakers, and wildlife explorers, but its waters are filled with hidden hazards. CHS Chart 3670 provides the "ground-truth" data required for safe passage:

• High-Resolution Island Mapping: Offers the granular detail necessary to navigate the narrow passages between Effingham, Turtle, and Gilbert Islands.

• Safe Passage and Channels: Detailed bathymetry for the Coaster Channel, Peacock Channel, and Thiepval Channel, ensuring larger vessels can move through the archipelago without grounding.

• Safety for Small Craft: Explicitly marks the locations of drying rocks, reefs, and shoals that are critical for kayakers and small boaters navigating the inter-island zones.

• Seafloor & Anchorage Data: Identifies the nature of the sea bottom (sand, mud, or rock), providing essential information for securing safe anchorages within the National Park.
